Food Safety Standards




4556 NEW ZEALAND GAZETTE No. 170

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 the 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. 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. These LOQs constitute CF in the prescribed formula. These selected LOQs are consistent with those published in the Australian Market Basket Survey (1996).

It is acknowledged that the LOQ may change with time as analytical techniques become more sensitive. The Standard will be reviewed periodically in respect to this issue.

The calculation for mixed food for all other contaminants with an ML will assume that the contributing commodity, eg. 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 unbolded type in column 1 of the Table to this clause.

  metal contaminant means a substance listed in bold type 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 2 of the Table to this clause, expressed in mg/kg, unless otherwise specified.

(3) Where a mixed food contains food or class of foods listed in unbolded type in column 1 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).
