The Pest Management Regulatory Agency (PMRA) of Health Canada has established maximum residue limits (MRLs) for the chemical hexythiazox in most food products imported or sold in Canada.
Hexythiazox is an acaricide and miticide used to control mites on a variety of food plants, including citrus, corn, beans and berries. However, according to Health Canada, a number of recent studies have determined that dietary exposure to hexythiazox residue may pose a hazard to human health.
The new hexythiazox MRLs are applicable to 15 different types of food products. Food products for which no MRL is specified must not contain any hexythiazox residue.
Canada’s hexythiazox MRLs fall under the authority of that country’s Pest Control Products Act, and became effective as of the end of October 2016.
More information on Canada’s hexythiazox MRLs, including details on specific limits, is available at the Health Canada website.
