For more details on the MRLs that were set in the recent amendment, refer to the notice on the NZFSA website (http://www.nzfsa.govt.nz/policy-law/legislation/food-standards/bn-07-038-nz-mrl-food-standards-amendment-2.pdf).

Public consultation

Soon the third amendment to the MRL standard for 2007 will be submitted for public consultation. This round will also seek to consolidate the MRL standard and all of its 2007 amendments into the 2008 MRL standard. The proposed MRLs will be available on the NZFSA website for comment in the near future.

In addition, because certain agricultural chemical uses are becoming redundant, it is proposed to delete the following MRLs from the standard:

Compound	Food	Maximum Residue Limit (mg/kg)
Azinphos-methyl	Vegetables*	2
Benalaxyl	Grapes Tomatoes	0.5 0.5
Bromopropylate	Citrus fruits	3
sec-Butylamine	Citrus fruits	30
Methidathion	Citrus fruits	2
Methylene chloride	Spices	30
Naled	Berries and other small fruits Vegetables	2 2
Nitrothal-isopropyl	Pome fruits	0.2
Phosmet	Kiwifruit Other fruit	15 10

The deleted MRL for azinphos-methyl on vegetables will be replaced with an MRL of 0.05mg/kg* for potatoes to represent the remaining use patterns.
