Food residues – new NZFSA booklet explains all

A new booklet, which aims to explain the complexities around chemical residues in food, has been produced by the New Zealand Food Safety Authority (NZFSA).

Agricultural Compound Residues in Food takes the reader on a question-and-answer journey which starts by explaining what an agricultural compound is, why they’re used, why they’re allowed and how safety limits are set.

It explains, in easy to understand language, what terms such as maximum residue limit (MRL) and Acceptable Daily Intake (ADI) mean, how you can tell the difference between them, and what happens if a residue exceeds the MRL.

The ‘cocktail effect’ of combined residues is also dealt with, as are concerns that chemicals that may be ‘banned’ overseas are regularly used on New Zealand foods.

The booklet also explains the laws that apply to the use of agricultural compounds and NZFSA’s role in monitoring their use in our food supply and New Zealanders’ exposure to them.

Debbie Morris, NZFSA’s Director of Agricultural Compounds and Veterinary Medicines says: “We acknowledge and understand that some people are very concerned about the use of chemicals in their food. We hope this booklet will help to alleviate those concerns and provide them with a better understanding of the role agricultural chemicals play in ensuring the quality and safety of the food we eat.”

Residue levels in New Zealand’s food supply are mostly at the levels expected and results from NZFSA’s most recent monitoring and surveillance programmes show that farmers, growers and importers are committed to ensuring that this continues.

NZFSA advises all consumers to follow these simple steps:

• wash fresh produce thoroughly to remove dirt and soil

• around the home and garden, always follow label instructions for mixing and applying chemicals and wait for the entire withholding periods

• use compost from reputable firms, and make sure it is well mixed into your soil

• eat undamaged produce that looks fresh, to minimise exposure to natural toxins

• prepare and eat your food in the commonly accepted manner and, if it is to be cooked, make sure it is properly cooked.
