✨ Agricultural and Veterinary Chemical Residue Limits



4566 NEW ZEALAND GAZETTE No. 170

3 Extraneous residue limits

(1) The permitted ERL for a chemical in food is listed in Schedule 2.

(2) If an ERL for a chemical is not listed in this Standard there must be no detectable
residue of that agricultural chemical in that food.

4 Determination of maximum and extraneous residue limits

(1) Schedule 4 of this Standard specifies the portion of food to which the MRL or ERL
applies.

(2) Unless Schedules 1 or 2 specify a separate MRL or ERL for a processed food, the
MRL or ERL applies to that food whether raw or processed.

(3) Where a food contains more than one of the chemicals listed in any group in
Schedule 3 of this Standard, the combined proportions of those chemicals must not exceed
unity.

Sample calculation

Amount of chemical A present / MRL or ERL for chemical A + Amount of chemical B present / MRL or ERL for chemical B ≤ 1

(4) Where there is no MRL or ERL specified for a chemical in a food which has
ingredients, the MRL or ERL of the chemical in that food is the combined
proportionate quantities of the MRL or ERL specified for the ingredients of that
food.

Sample calculation

MRL1 = Total A x MRL A + Total B x MRL B
Total Total

In this calculation -

MRL1 = the MRL which applies to the chemical in the mixed food
MRL A = the MRL for the chemical which applies to food A
MRL B = the MRL for the chemical which applies to food B
Total A = total weight of food A
Total B = total weight of food B
