Australia New Zealand Food Standards Code – Standard 1.4.1 – Contaminants and natural toxicants

The Standard’s operative concepts are: (1) the application point , the portion of food ordinarily consumed; (2) the catalogue of limits , Schedule 19; (3) the composite‑food calculation , the ML formula and defined variables; (4) special rules for mercury in fish , S19,7 reference; (5) the background calculation factor CF for ingredients without a specific maximum; and (6) an explicit exception for honey/comb honey.

Application point: Subsection 1.4.1,2(1) directs that the limits in the Standard apply to the portion of foods ordinarily consumed. That phrase identifies the sampling or unit of measurement to which a maximum level is tied, rather than, for example, the whole packaged unit. The text does not define “ordinarily consumed” within the Standard itself; practitioners must therefore rely on the Code’s other definitions or established sampling interpretations elsewhere in the Code (the Standard cross‑references various parts of the Code, see notes and cross‑references).

Schedule‑based maximums: Section 1.4.1,3(1) makes compliance turn on whether the level of a listed contaminant or natural toxicant in a listed food is “not greater than the corresponding amount listed in that Schedule.” The Standard delegates the detailed substance and food specifications to Schedule 19. The accompanying note explicitly lists the categories contained in Schedule 19: metal contaminants, non‑metal contaminants, natural toxicants and average and maximum levels for mercury in fish.

Composite foods and the ML equation: For foods for sale with two or more ingredients, where at least one ingredient is listed in Schedule 19, subsection 1.4.1,3(3) requires that the level of the contaminant or toxicant in the final product must not exceed the amount ML calculated by the equation shown in the Standard. The Standard defines the equation’s variables: N (number of ingredients with a specified maximum), MLj (either the mean permitted level for mercury under S19,7 or, otherwise, the maximum level permitted under subsection (1) for the jth ingredient), Totalj (weight in grams of the jth ingredient), CF (a background calculation factor with explicit numeric values for lead and cadmium and 0 mg/kg for other substances), and Total (total weight in grams of the food for sale). The Standard thus operationalises how ingredient‑level maxima translate into final product limits.

Treatment of mercury in fish: Mercury is handled separately by reference to section S19,7. Subsection 1.4.1,3(2) requires that mercury in fish, calculated under S19,7, must comply with the appropriate subsection of S19,7, which contains average and/or maximum limits. In the ML calculation for composite foods MLj is specifically defined in the case of mercury as the mean level permitted under S19,7.

Background calculation factor (CF): The Standard introduces a CF to account for representative contaminant levels in foods for which no specific maximum is set in Schedule 19. CF has discrete non‑zero values for lead (0.01 mg/kg) and cadmium (0.005 mg/kg) and is 0 mg/kg for other substances. The CF is intended to allow for representative contaminant levels in unspecified ingredients when calculating ML for composite foods (1.4.1,3(3) variable definitions).

Honey and tutin: Section 1.4.1,4 creates a narrow exception to another Code provision (1.1.1,9) for honey and comb honey in the context of applying 1.4.1,3. It also preserves a transitional deeming rule for retail‑packaged honey that was packaged before the P1029 tutin variation’s commencement, deeming it to comply with the tutin level in S19,6 provided it otherwise complied with the Code pre‑variation (1.4.1,4(1)-(2)).

Framing language: The Standard contains a policy instruction that contaminants should be kept “as low as reasonably achievable,” and it situates the limits as being set where FSANZ determined there was “a potential risk to public health and safety if the prescribed limits are exceeded” (note 4). The instrument is an element of the regulatory framework; it does not, in this text, spell out sampling methods, laboratory standards, or penalties in the Standard itself but sits within the Code and the application Acts.

Primary obligations attach to those responsible for placing food for sale that contains substances covered by Schedule 19. The Standard operates in the Code and applies to “food for sale” (see the cross‑reference to section 1.1.1,10(6) in note 3), which in turn means businesses in the supply chain that make food available to consumers: manufacturers, formulators of multi‑ingredient products, packers, importers and retailers. The text explicitly contemplates foods for sale with two or more ingredients (1.4.1,3(3)), so companies that make composite products must apply the ML calculation and therefore will need ingredient‑level information (MLj and Totalj) to demonstrate compliance.

Suppliers of single‑ingredient foods that are listed in Schedule 19 are affected directly because subsection 1.4.1,3(1) requires the contaminant level in such a food not be greater than the amount listed in Schedule 19. Where Schedule 19 lists particular foods in relation to a contaminant or toxicant, the obligation attaches to food of that kind (1.4.1,2(2) cross‑references Schedule 22 for descriptions). The Standard’s definition references to “vegetables” and “any other particular food” are to foods as described in Schedule 22 (1.4.1,2(2)(a)-(b)), so producers and processors of foods captured by Schedule 22 must consult that schedule for the precise scope.

Seafood and fish producers, processors and traders have a specific interest because mercury in fish and fish products is treated specially by S19,7 (1.4.1,3(2)). For mercury, MLj in composite products is the mean level permitted under S19,7, which affects formulators using fish ingredients.

Beekeepers, packers and sellers of honey and comb honey are specifically affected by the honey provisions in 1.4.1,4. The Standard temporarily exempts application of section 1.1.1,9 to honey/comb honey when applying 1.4.1,3 and provides a transitional deeming rule for pre‑variation retail‑packaged honey in relation to the tutin level in S19,6 (1.4.1,4(1)-(2)). The inclusion of this tailored transitional rule means certain honey already packaged before the P1029 variation’s commencement is treated as compliant regarding tutin, if it otherwise complied with the Code.

Regulators and enforcement agencies across jurisdictions are affected via the Code’s incorporation into domestic law: the Standard is issued under the Food Standards Australia New Zealand Act 1991 (Cth) (note 1) and the Code’s provisions apply in New Zealand through the Food Act 2014 (NZ) (note 2). The Standard therefore allocates regulatory duties to domestic enforcement regimes that give effect to the Code in each jurisdiction. The Standard itself does not set out enforcement mechanisms or penalties, but cross‑references to the application Acts indicate that enforcement and penalties operate through those frameworks (see note 3 and the references to the application Acts).

Finally, consumers are indirectly affected because the Standard sets allowable maximums for contaminants and toxicants in foods they purchase, and it contains the express policy expectation that concentrations “should be kept as low as reasonably achievable” (note 4), which may shape industry practices and labelling, market availability and sourcing decisions.

Duties

• Comply with Schedule 19 limits: The core duty is that the level of any contaminant or natural toxicant listed in sections S19,4, S19,5 or S19,6 in a food listed in relation to that contaminant or toxicant must not exceed the corresponding amount in Schedule 19 (1.4.1,3(1)). This requirement applies to the portion ordinarily consumed (1.4.1,2(1)). Practically, the duty attaches to the food for sale. The cross‑reference to section 1.1.1,10(6) in note 3 confirms that food for sale must comply with Code provisions relating to composition or presence of specified substances.

• Comply with mercury rules for fish: Mercury in fish and fish products must be calculated under S19,7 and comply with either subsection S19,7(1) or S19,7(2) as appropriate (1.4.1,3(2)). In composite foods, MLj for mercury is the mean level permitted under S19,7 (1.4.1,3(3) variable definitions).

• Apply the ML calculation for composite foods: For foods for sale with two or more ingredients, at least one of which is listed in Schedule 19, the level of a listed contaminant or toxicant in the final product must not exceed ML, where ML is calculated by the equation reproduced in the Standard (1.4.1,3(3)). The Standard defines N, MLj, Totalj, CF and Total for that calculation; CF has specified numerical values for lead and cadmium and is zero for other substances.

• Observe the honey exception and transition: Those dealing in honey and comb honey must note that section 1.1.1,9 does not apply to honey/comb honey for purposes of section 1.4.1,3 (1.4.1,4(1)). Honey packaged for retail sale before commencement of the P1029 tutin variation is deemed to comply with the tutin level in S19,6 if the product otherwise complied with the Code before the variation (1.4.1,4(2)).

• Keep contaminant levels ALARA: The Standard issues a policy direction that concentrations should be kept “as low as reasonably achievable” and that limits were set where FSANZ determined a potential risk to public health and safety existed if the prescribed limits were exceeded (note 4). This is an interpretive duty pointing to a risk‑management approach.

Rights and practical entitlements

• Reliance on Schedule text: Regulated parties can determine their compliance obligations by consulting Schedule 19 and Schedule 22, as the Standard expressly delegates the detailed specification of materials and food descriptions to those schedules (1.4.1,3(1); 1.4.1,2(2)). The Standard therefore provides a clear route to discover the substantive limits and food identifications.

• Transitional protection for pre‑variation honey: Honey packaged for retail sale before the P1029 tutin variation takes effect is treated as compliant with the tutin limit in S19,6 where it otherwise complied with the Code before the variation (1.4.1,4(2)). That is a specific benefit to those with stock packaged before the amendment’s commencement.

• Predictable composite calculation: The ML equation and the defined CF values create a predictable arithmetic method for combining ingredient maxima into a final product limit. The Standard sets out the variables explicitly (N, MLj, Totalj, CF, Total), so businesses have a formulaic path to calculate the applicable ML for a composite food (1.4.1,3(3) and variable definitions).

What the Standard does not do in this text

• The Standard does not itself spell out sampling protocols, laboratory methods, or enforcement sanctions. It situates its limits within the application Acts and the broader Code and relies on Schedules for the specific numerical limits. Enforcement mechanisms and the operational detail of testing are therefore to be found elsewhere in the Code and the relevant application Acts. The Standard likewise does not purport to provide an exhaustive glossary for every term , it refers to Schedules for many food descriptions (1.4.1,2(2)).

The Standard does not itself set criminal or civil penalties in the text provided. Instead, it is a Code standard published under the Food Standards Australia New Zealand Act 1991 (Cth) and incorporated into domestic regimes. The source material explicitly directs that the Standard is “to be read in the context of the requirements imposed in the application Acts that food must be safe and suitable for human consumption” and cites the legal effect that a “food for sale must comply with any provisions of this Code relating to the composition of, or the presence of specified substances in, food of that kind” (note 3, referencing section 1.1.1,10(6)). From the text this means that enforcement and any applicable penalties operate through the application Acts and the domestic statutes and regulations that give legal force to the Code in each jurisdiction (for example, the Federal/State/Territory and New Zealand implementation mechanisms referenced in notes 1 and 2).

Operationally, the Standard creates obligations that enforcement agencies assess against the Schedule 19 limits and the composite‑food calculation. The Standard makes compliance judged on the contaminant or toxicant level in the food for sale relative to the applicable Schedule 19 amount (1.4.1,3(1)-(3)). Because the Standard treats the portion ordinarily consumed as the measurement unit (1.4.1,2(1)), enforcement and sampling strategies will typically need to define clearly which unit is tested to demonstrate compliance with the relevant Schedule limit. The Standard itself contains no sampling or laboratory methodology; enforcement agencies will therefore rely on protocols elsewhere in the Code, in the application Acts or in jurisdictional enforcement guidance to determine how to test and adjudicate compliance.

There are two practical enforcement consequences embedded in the Standard’s text that have procedural implications:

• Composite foods require ingredient‑level information: To demonstrate compliance under 1.4.1,3(3) a regulator evaluating a composite product will expect data on the weights (Totalj), the applicable ingredient level MLj for those ingredients listed in Schedule 19 or the CF for unspecified ingredients, and the calculation that produces ML. Regulated businesses therefore bear the evidentiary burden of producing formulation and testing data to show the final product’s contaminant level does not exceed the ML calculated by the Standard.

• Special mercury and honey rules change enforcement focus: For fish and fish products, enforcement must apply the S19,7 calculation for mercury (1.4.1,3(2)), which may require different analytic thresholds (mean vs maximum) depending on S19,7’s structure. For honey, the exemption and transitional deeming rule in 1.4.1,4 shifts the applicable legal test in a narrow set of cases (retail‑packaged honey prior to the P1029 tutin variation).

Because the Standard is part of the Code, the typical enforcement mechanisms and penalties that apply to Code breaches are found in the relevant application Acts and domestic implementing legislation. The Standard’s text therefore creates substantive obligations, but the means of enforcing those obligations and the sanctions for non‑compliance are not specified in the Standard itself and must be sought in the application Acts and enforcement instruments of each jurisdiction.

The Standard is expressly an instrument under the Food Standards Australia New Zealand Act 1991 (Cth) and a component of the Australia New Zealand Food Standards Code (note 1). The Code’s provisions apply in New Zealand by incorporation or adoption under the Food Act 2014 (NZ) (note 2). The Standard therefore operates not in isolation but as a Code standard whose legal effect and enforcement are mediated through domestic implementation laws.

Relevant cross‑references within the Code include:

• Section 1.1.1,10(6) (referenced in note 3), which provides that a food for sale must comply with Code provisions relating to composition or presence of specified substances in that food. The effect of this cross‑reference is that the substantive limits in this Standard become mandatory obligations for food for sale by operation of the wider Code framework.

• Section 1.1.1,9 is expressly disapplied for honey and comb honey for the purposes of applying 1.4.1,3 (1.4.1,4(1)). The Standard therefore amends the internal interaction between Code provisions for a defined category of food.

• Schedules 19 and 22 are integral to the Standard’s operation. Schedule 19 contains the substance‑by‑substance and food‑by‑food numerical maxima (1.4.1,3(1) and the note). Schedule 22 provides the descriptions that define “vegetables” and “any other particular food” for the Standard’s purposes (1.4.1,2(2)). The Standard’s compliance rules therefore depend on other Code instruments and schedules that supply detailed identifiers and numerical limits.

• S19,7 is a separate sub‑provision in Schedule 19 that prescribes how mercury in fish and fish products is to be calculated and what must be complied with (1.4.1,3(2)); the Standard requires compliance with the relevant subsections of S19,7.

• The Standard’s commencement and amendment notices are made under section 92 of the Food Standards Australia New Zealand Act 1991 (Cth) and references section 93 for the commencement process in the Gazette notes. The Amendment History confirms that amendments are made under s92 unless otherwise indicated and that commencement information is recorded.

Interactional consequences and practical cross‑links

• The Standard delegates the operational detail (numerical limits, food descriptions and mercury formulas) to schedules and other Code provisions. Practitioners must therefore consult Schedules 19 and 22 and the Code’s implementation provisions (for example, the sampling and analysis guidance, and the application Acts) to obtain the full legal picture. The Standard’s text repeatedly points users to other Code provisions and the application Acts.

• The transitional and savings provision for honey (1.4.1,4(2)) demonstrates how variations to the Code (such as Proposal P1029) affect existing stock and require specific deeming or exemption language to manage the transition between old and new limits. Users must therefore track Code variations and their commencement dates to know which stock is covered by transitional relief.

• Because the Standard is part of a bi‑jurisdictional Code, compliance in New Zealand depends on adoption mechanisms under the Food Act 2014 (NZ), meaning that enforcement and any variations to the Standard may have slightly different operational pathways in the two countries despite substantive alignment in the Code text.

The compilation states this is compilation No. 2 of Standard 1.4.1 as in force on 1 September 2022 (up to Amendment No. 211). The Standard was published in the Food Standards Gazette No. FSC96 on 10 April 2015 as part of Amendment 154 and has since been amended. The Amendment History summarises the following specific amendments recorded in the compilation table:

• Amendment No. 161: Registered as F2016L00120 (Gazette entries 2018 Feb 2016 and FSC10322 Feb 2016) with commencement 1 March 2016. This amendment amended section 1.3.1,3(3) to correct a typographical error in the formula. The table entry records the amendment as “am” and describes it as a correction of a typographical error in the formula.

• Amendment No. 157: Registered as F2015L01374 (Gazette entries Sept 2015 and FSC993 Sept 2015) with commencement 1 March 2016. This amendment added section 1.4.1,4: a new section relating to tutin in honey that had previously been included in the Code as part of Proposal P1029. The table entry records the amendment as “ad”.

• Amendment No. 211: Registered as F2022L01118 (Gazette entries 26 Aug 2022 and FSC1511 Sept 2022) with commencement 1 September 2022. This amendment repealed and substituted subsection 1.4.1,2(2), adding a new subsection relating to a reference to vegetables. The table entry records the amendment as “rs”.

The compilation notes that these amendments are made under section 92 of the Food Standards Australia New Zealand Act 1991 unless otherwise indicated and that amendment entries do not have a specific date for cessation unless indicated.

The document also explains how uncommenced amendments or provisions ceasing to have effect will be reflected (shaded boxed text with relevant commencement or cessation date), and provides standard abbreviations used in the table (ad, am, exp, rep, rs). The compilation information states it was prepared by Food Standards Australia New Zealand on 1 September (year truncated in the source, shown as “1 September 20” in the provided text), and reflects the state of the Standard up to Amendment No. 211.

Practical effects of the amendment history

• The typographical correction to the composite‑food formula indicates the numerical calculation has been active and required correction post‑publication. Users should therefore rely on the current, amended text (and any FRLI registered version) to ensure accurate ML calculations (Amendment No. 161).

• The insertion of the honey/tutin provision via Amendment No. 157 shows the Standard is responsive to specific food safety issues requiring bespoke transitional rules. Businesses trading in honey need to monitor Proposal and Variation notices to determine whether transitional deeming applies to their stock (Amendment No. 157).

• The replacement of subsection 1.4.1,2(2) by Amendment No. 211 alters the Standard’s definitions or references to “vegetables,” which directly affects which foods are captured by Schedule 19 entries that use the term vegetable. Businesses and regulators must ensure they consult the post‑1 September 2022 wording of 1.4.1,2(2) and the updated Schedule 22 descriptions when determining applicability.

The compilation provided includes no litigation history, no case references and no recorded judicial decisions in respect of this Standard. The source does not identify any court or tribunal proceedings, nor does it list appeals or other adjudications arising from the application of Standard 1.4.1.

Because the Standard is part of the Code and is enforced through the application Acts (the Food Standards Australia New Zealand Act 1991 (Cth) and domestic implementing legislation in Australia and New Zealand), potential litigation arising from alleged non‑compliance would typically be brought under those Acts or relevant domestic food safety legislation. The Standard’s text itself does not report any such proceedings, nor does the Amendment History cite any litigation‑driven changes.

For practitioners seeking precedents or judicial interpretations of how Schedule 19 limits, the composite ML calculation, the CF background factors, or the honey transitional provision have been applied in contested cases, the absence of litigation entries in this compilation means that they must search external case law databases, tribunal decisions and administrative rulings not included in this Standard’s compilation to determine whether any judicial or administrative authority has interpreted these provisions.

In short, the source provides no litigation history; it neither reports cases nor supplies judicial interpretive material. Where enforcement disputes have occurred or precedent exists, that material is outside the compilation provided and must be located in case law or enforcement decision repositories.

• Schedules contain the substance of the limits but are not included in this compilation: The Standard delegates the essential, numeric limits and food descriptions to Schedule 19 and Schedule 22 (1.4.1,3(1); 1.4.1,2(2)). Practitioners cannot determine actual maximum values from the text excerpt provided here; they must consult Schedule 19 for the specific contaminant and food pairings and Schedule 22 for the precise food descriptions that determine whether a given food is captured by a Schedule entry.

• Portion ordinarily consumed matters for sampling: The limits apply to the “portion of foods that is ordinarily consumed” (1.4.1,2(1)). Enforcement and compliance testing will therefore hinge on which portion is regarded as “ordinarily consumed.” The Standard does not define that phrase in this text, so ambiguity over the sampling unit (serving size, retail unit, prepared portion) can arise. Parties should identify the intended measurement unit consistent with other Code provisions and any relevant jurisdictional sampling guidance.

• Composite‑food calculation requires accurate ingredient data: To calculate ML under 1.4.1,3(3) the regulated party needs the number of ingredients subject to Schedule 19 (N), for each such ingredient the applicable MLj (either mean for mercury under S19,7 or the Schedule 19 maximum), the total weight of each such ingredient (Totalj), the CF where an ingredient has no specific Schedule maximum, and the Total weight of the final product. Errors or incomplete documentation of ingredient composition or weights will compromise the calculation and the ability to demonstrate compliance. Note that Amendment No. 161 corrected a typographical error in a related formula (1.3.1,3(3)), demonstrating the potential for formulaic complexity and the need to use current consolidated text.

• CF values are asymmetric and mostly zero: The background calculation factor is numerically specified and non‑zero only for lead (0.01 mg/kg) and cadmium (0.005 mg/kg); for other substances CF = 0 mg/kg (1.4.1,3(3) variable definitions). This means that when an ingredient has no specific maximum in Schedule 19, the calculation treats lead and cadmium as having small representative values but treats other contaminants as having no background allowance. Businesses formulating composite products with ingredients not explicitly covered by Schedule 19 must therefore pay particular attention to how lead and cadmium are treated versus other substances.

• Special mercury rules can change whether mean or maximum applies: The Standard requires mercury in fish and fish products to be calculated under S19,7 and to comply with the relevant subsection (1.4.1,3(2)). The MLj definition for mercury is the mean level permitted under S19,7. Differences between mean and maximum approaches can materially affect both product compliance and testing protocols.

• Honey transitional rule is narrow and conditional: Section 1.4.1,4(2) deems honey and comb honey packaged for retail sale before the P1029 tutin variation commenced to comply with the tutin level in S19,6 only if the product “otherwise complied with the Code before that variation commenced.” The deeming does not give carte blanche to non‑complying products; the condition may require evidentiary proof that the pre‑variation product complied with the relevant Code provisions.

• The Standard omits enforcement detail: The text does not specify how breaches are detected, what sampling or lab standards apply, or the specific penalties available for breach. Those elements are in the application Acts and implementing instruments. Parties should not rely on the Standard alone to plan compliance and enforcement strategies.

• Time of commencement matters for stock: The commencement and amendment history shows the Standard and variations have specific commencement dates (commencement note; Amendment History). Where product stock was produced or packaged before a variation’s commencement (as in the P1029 tutin example), transitional rules may apply. Supply‑chain actors must monitor amendment commencement dates closely to determine whether they have transitional cover for standing inventories.

• The Standard’s text refers to other Code provisions that may alter meaning: The disapplication of 1.1.1,9 for honey/comb honey and the cross‑references to 1.1.1,10(6), S19,7 and Schedule 22 mean plain reading of 1.4.1 without reading those provisions risks error. Practitioners must read the cross‑referenced provisions in tandem.

The Standard sets out substantive calculation and limit obligations; compliance therefore requires operational steps that align with the Standard’s formulaic and schedule‑based approach. The steps below are drawn from the Standard’s provisions and the logical requirements they impose.

1. Identify whether the food is captured and what unit to measure

• Determine whether the food is “food for sale” and the portion “ordinarily consumed” (1.4.1,2(1); note 3 referencing s 1.1.1,10(6)). Decide and document the measurement unit that corresponds to the “portion ordinarily consumed” for your product, and ensure that this unit is used consistently for testing and reporting.

2. Consult Schedule 19 and Schedule 22

• Obtain the current Schedule 19 to identify the specific contaminants or natural toxicants listed for the food in question and the numerical maximums applicable to that food (1.4.1,3(1) and note). Obtain Schedule 22 for the descriptive identification of foods (1.4.1,2(2)) so you can confirm whether your product falls within any food descriptions used in Schedule 19 entries.

3. For single‑ingredient foods listed in Schedule 19

• Test and verify that the contaminant or natural toxicant level in the portion ordinarily consumed does not exceed the Schedule 19 amount (1.4.1,3(1)). Keep records of testing, test dates and laboratory results to show compliance.

4. For composite foods with two or more ingredients (at least one listed in Schedule 19)

• Apply the ML calculation required by subsection 1.4.1,3(3). Collect and retain the data needed:
  • N: the number of ingredients in the product for which Schedule 19 sets a maximum.
  • For each such ingredient j, identify MLj: for mercury, MLj is the mean level permitted under S19,7; for other substances MLj is the maximum level permitted under subsection (1) as listed in Schedule 19 (1.4.1,3(3) variable definitions).
  • For each such ingredient j, record Totalj: the total weight in grams of that ingredient in the finished product.
  • CF: where an ingredient has no specified maximum in Schedule 19, apply the CF value: lead 0.01 mg/kg, cadmium 0.005 mg/kg, and 0 mg/kg for other substances (1.4.1,3(3) variable definitions).
  • Total: the total weight in grams of the food for sale.
• Run the calculation using the Standard’s equation as published in the Code text. Because the Standard has been subject to a correction (Amendment No. 161 corrected a typographical error in the formula), ensure you use the consolidated, current text when performing the calculation.

5. Mercury in fish and fish products

• Where the contaminant is mercury in fish, calculate compliance under S19,7 and then apply the S19,7 mean or maximum requirements as appropriate (1.4.1,3(2)). For composite foods containing fish ingredients, use MLj as the mean level permitted under S19,7 for the fish ingredient component in the ML calculation (1.4.1,3(3) variable definitions).

6. Honey and comb honey specific steps

• If trading in honey or comb honey, note that the Standard disapplies section 1.1.1,9 for purposes of applying 1.4.1,3 (1.4.1,4(1)). If you have honey that was packaged for retail sale prior to the commencement of the P1029 tutin variation, document the packaging dates and evidence that the product otherwise complied with the Code before that variation commenced, because such stock is deemed to comply with the new S19,6 tutin level only if it otherwise complied with the pre‑variation Code (1.4.1,4(2)).

7. Recordkeeping and evidentiary posture

• Maintain complete and contemporaneous records that support the ML calculation and any testing undertaken: ingredient sourcing and supplier specifications, batch formulations listing Totalj and Total, test results showing contaminant concentrations in ingredients and the finished product, calculation worksheets applying the CF where appropriate, and dates of packaging where transitional relief may apply to honey. The Standard’s composite calculation makes ingredient weights and MLj values central to demonstrating compliance.

8. Keep contaminant levels as low as reasonably achievable (ALARA)

• The Standard contains the policy direction that concentrations “should be kept as low as reasonably achievable” (note 4). Adopt hazard‑control and supplier management practices that aim to minimise contaminant levels in raw materials and final products, recognising that the Standard bases its numeric limits on risk‑assessment determinations that exceedances pose potential public health risks.

9. Monitor amendments and commencement dates

• Because the Standard has been varied (see Amendment History), track amendment notices and commencement dates published under the Food Standards Australia New Zealand Act 1991 s92 and s93 (commencement note and Amendment History). Changes to schedules or to the definitions in Schedule 22 can alter which foods are covered or what numerical limits apply; transitional rules (as with P1029 tutin) may affect treatment of existing stock.

10. Coordinate with enforcement and sampling guidance

• The Standard does not itself provide sampling or laboratory methods or enforcement penalties. To operationalise compliance testing and to understand the evidentiary format that enforcement agencies will accept, consult the Code’s additional provisions, jurisdictional sampling and analysis guidance, and the application Acts that give the Code legal effect. Ensure any laboratory testing is performed to the standard and methods accepted by the relevant enforcement authority.

Who pays and practical cost drivers

• Testing and analytical costs are the immediate, predictable outlays for parties who must demonstrate compliance, particularly for composite foods that require ingredient testing or validated supplier data to run the ML calculation. The need to document ingredient weights and MLj values imposes recordkeeping and possibly formulation‑control costs.

• Reformulation or ingredient substitution may be necessary where composite calculations produce an ML below achievable contaminant levels, or where raw material supply contains contaminants at levels that make compliance with Schedule 19 infeasible. Those costs are borne by producers and can affect sourcing and pricing decisions.

• Inventory management costs arise where transitional rules limit the ability to sell post‑variation stock or where stock packaged before a variation must be segregated and documented (1.4.1,4(2) example). Compliance requires administrative effort to trace packaging dates and pre‑variation Code compliance.

In short, compliance requires accurate schedule consultation, collection and retention of ingredient and testing data, application of the Standard’s ML calculation (including CF where applicable), careful treatment of mercury in fish and of honey transitional rules, and ongoing monitoring of Code variations and commencement dates.
