Standard 1.4.1

 

Contaminants and Natural Toxicants

 

 

Purpose

 

This Standard sets out the maximum levels (MLs) of specified metal and non-metal contaminants and natural toxicants in nominated foods.  As a general principle, regardless of whether or not an ML exists, the levels of contaminants and natural toxicants in all foods should be kept As Low As Reasonably Achievable (the ALARA principle).

 

An ML has been established only where it serves an effective risk management function and only for those foods which provide a significant contribution to the total dietary exposure.  Food not listed in this Standard may contain low levels of contaminants or natural toxicants.   However, MLs have not been assigned to these foods because they present a low public health risk.  The general provisions of the Food Acts relating to the availability of safe foods apply to all foods. 

 

MLs have been set at levels that are consistent with public health and safety and which are reasonably achievable from sound production and natural resource management practices.  Consideration has also been given to Australia’s and New Zealand’s international trade obligations under the World Trade Organization’s Agreement on the Application of Sanitary and Phytosanitary Measures and the Agreement on Technical Barriers to Trade.

Clauses

 

1             Interpretation

 

(1)           In this Standard –

 

arsenic is considered to be a metal.

 

maximum level (ML) means the maximum level of a specified contaminant, or specified natural toxicant, which is permitted to be present in a nominated food expressed, unless otherwise specified, in milligrams of the contaminant or the natural toxicant per kilogram of the food (mg/kg).

 

(2)           Where food contains a metal and any other chemical species of that metal, all chemical species of that metal must be expressed as the metal.

 

(3)           The maximum level must be calculated for the edible content of the food that is ordinarily consumed.

 

(4)           The level for a food which is dried, dehydrated or concentrated is to be calculated on the basis of the mass of the food, or the mass of the ingredients of the food, prior to drying, dehydration or concentration determined from one or more of the following –

 

(a)          the manufacturer’s analysis of the food; and

(b)          calculation from actual or average quantity in water in the ingredients used; and

(c)          generally accepted data.

(5)           The level for seaweed whether dried, dehydrated, concentrated or not is to be calculated with respect to the mass of the seaweed at 85% hydration.

 

(6)           For a mixed food, the prescribed formula for the purposes of this Standard is –

 

ML1 =

 

Where –

 

ML1 = ML which applies to the contaminant or natural toxicant in the mixed food (mg/kg)

MLA = ML for contaminant or natural toxicant in food A (mg/kg)

MLB = ML for contaminant or natural toxicant in food B (mg/kg)

Total = total weight of mixed food (g)

Total A = total weight of food A in the mixed food (g)

Total B = total weight of food B in the mixed food (g)

CF = Background Calculation Factor where, in the case of –

 

(a)          lead, CF = 0.01 mg/kg;  and

(b)          cadmium, CF = 0.005 mg/kg; and

(c)          other contaminants, CF = 0

 

Editorial note:

 

It is recognised both lead and cadmium are ubiquitous in the environment and occur at low levels in foods other than those listed in this Standard.  Therefore, in order to assist with the enforcement of MLs in mixed foods which may contain these contaminants, the calculation requires the inclusion of a representative contaminant level for those foods that do not have an allocated ML.  In the past, an ML was set for ‘all other foods’.  As the category for ‘all other foods’ was discontinued, a representative level is selected for the contaminants cadmium and lead.  These levels are set at the limit of quantification (LOQ), and are 0.01 mg/kg for lead and 0.005 mg/kg for cadmium. 

 

The calculation for mixed food for all other contaminants with an ML will assume that the contributing commodity, e.g. peanuts in peanut sauce, contains all of the contaminant.

 

2             Maximum levels of metal contaminants in food

 

(1)           In this clause –

 

food means the food or class of foods listed in Column 2 of the Table to this clause.

 

metal contaminant means a substance listed in Column 1 of the Table to this clause and includes compounds of a metal.

 

(2)           The maximum levels for metal contaminants in food are listed in Column 3 of the Table to this clause.

 

(3)           Where a mixed food contains food or a class of foods listed in Column 2 of the Table to this clause, the proportion of the metal contaminant permitted to be present in the mixed food (ML1) is calculated in accordance with the formula prescribed in subclause 1(6).

6             Sampling plan for mercury in fish, fish products, crustacea and molluscs

 

(1)           The methods specified in this clause are the prescribed methods for the sampling for analysis of mercury in fish, fish products, crustacea and molluscs.

(2)           For the purposes of this sampling plan –

 

(a)          A sample must consist of a prescribed number of sample units, and a sample unit must consist of a quantity, taken from the edible portions of the fish, fish products, crustacea or molluscs, sufficient for the purposes of analysis.

(b)          In the lot under investigation, the number of random sample units must be as detailed in paragraphs 6(3)(a) or 6(3)(b) of this Standard.

(c)          In the case of samplings where the prescribed number of sample units are not available, 5 sample units must be taken.

 

(3)           The number of random sample units to be taken for the purposes of analysis is as follows –


 

(a)          fish, fish products, including packaged fish –

 

(i)            lots up to and including 5 tonnes ... sample units from 10 fish, or 10 packages; or

(ii)           lots over 5 tonnes, up to 10 tonnes ... sample units from 15 fish, or 15 packages; or

(iii)          lots over 10 tonnes, up to 30 tonnes ... sample units from 20 fish, or 20 packages; or

(iv)          lots over 30 tonnes, up to 100 tonnes ... sample units from 25 fish, or 25 packages; or

(v)           lots over 100 tonnes, up to 200 tonnes ... sample units from 30 fish, or 30 packages; or

(vi)          lots over 200 tonnes ... sample units from 40 fish, or 40 packages.

 

(b)          crustacea, and molluscs, including packaged crustacea and molluscs –

 

(i)            lots up to and including 1 tonne ... 10 sample units, or 10 packages; or

(ii)           lots over 1 tonnes, up to 5 tonnes ... 15 sample units, or 15 packages; or

(iii)          lots over 5 tonnes, up to 30 tonnes ... 20 sample units, or 20 packages; or

(iv)          lots over 30 tonnes, up to 100 tonnes ... 25 sample units, or 25 packages; or

(v)           lots over 100 tonnes ... 30 sample units, or 30 packages.

 

(4)           Interpretation of the Analysis –

 

(a)          Samples with 10 or more sample units –

 

(i)            if the concentration of mercury in any of the sample units is greater than 1.0 mg/kg in the case of gemfish, billfish (including marlin), southern bluefin tuna, barramundi, ling, orange roughy, rays and all species of shark, or is greater than 0.5 mg/kg in the case of crustacea, molluscs and other fish which can be sampled in accordance with this clause the overall mean of the sample units should be examined; or

(ii)           if the overall mean of the lot is less than or equal to 1.0 mg/kg in the case of gemfish, billfish (including marlin), southern bluefin tuna, barramundi, ling, orange roughy, rays and all species of shark, or is less than or equal to 0.5 mg/kg in the case of crustacea, molluscs, and other fish which can be sampled in accordance with this clause and there are no individual sample units within the lot having a mercury concentration exceeding 1.5 mg/kg, the lot must be reported as complying with the standard.

(b)          Samples with 5 sample units –

 

(i)            if the overall concentration of mercury in the sample is less than or equal to 1.0 mg/kg in the case of gemfish, billfish (including marlin), southern bluefin tuna, barramundi, ling, orange roughy, rays and all species of shark, or is less than or equal to 0.5 mg/kg in the case of crustacea, molluscs and other fish which can be sampled in accordance with this clause and minced fish products, the lot must be reported as complying with the standard.

(c)          Notwithstanding subclause 1(4), the mercury content of dried or partially dried fish must be calculated on an 80% moisture basis.
