Testing Food for Fipronil Contamination

Background

Chick and eggsIn early June, eggs contaminated with the pesticide Fipronil were discovered in Belgium and the Netherlands. A treatment against ticks containing fipronil had been incorrectly used to treat poultry and, if consumed, fipronil can be harmful to humans.

The EU’s executive alarm system, the Rapid Alert System for Food and Feeds (RASFF), alerted several European countries that eggs contaminated with Fipronil may have crossed their borders, both eggs and poultry meat meant for human consumption have been affected by this scandal.

What is fipronil?

Fipronil is an insecticide used against pests including ants, fleas, lice, ticks, cockroaches and also red mites which are commonly found in poultry. It has been shown to be acutely toxic in animal experiments when ingested orally, absorbed through the skin, or when inhaled, and should therefore not be used on food producing animals.

The maximum allowed fipronil residue levels (the sum of both fipronil and its sulfone metabolite) for chicken eggs or chicken meat is 0.005 mg/kg of body weight.

How to accurately test for fipronil and fipronil metabolites.

Samples are best prepared using the QuEChERS method followed by testing using GC/MS, GC/MS/MS or LC/MS/MS techniques. We offer a complete range of analytical standards, certified reference materials, solvents, and columns for analysis of your food samples. Additionaly we also develop application methods for determining fipronil and its sulfone metabolite in raw eggs, chicken meat and mayonnaise.

Reference Materials and Standards

Our high quality Pestanal® analytical standards and TraceCERT® certified reference materials can help ensure that measurements lower than the maximum allowed residue level can be detected, and our double accredited manufacturing process to ISO/IEC 17025 and ISO 17034 gives you the assurance of accuracy.
