Fera food scientists are able to highlight, quantify and provide regulatory evidence to validate the levels of benzimidazoles, within a variety of foodstuffs.

Benzimidazoles are a large chemical family used to treat parasitic worm (nematode and trematode) infections in food producing animals. They are also used in treating other internal parasites, including liver fluke. Veterinary medicines such as benzimidazoles, offer key advantages when maintaining livestock quantity and quality, most notably through disease prevention. These advantages can often lead to overuse across the agri-food sector, which may put consumers at risk.

Veterinary drug residues, when consumed in significant quantities, can result in physiological effects being shared in humans. As a result, the concern about the possible occurrence of residues of this drug in human food has produced a need for analytical methods to monitor for this agent at trace residue levels.

As a result, legislative bodies charged with maintaining the safety of foodstuffs offered to consumers have defined Maximum Residue Limits (MRLs) for a range of residues. MRLs for benzimidazoles are defined in Commission Regulation (EU) 37/2010 (or as amended), which apply to a range of tissues from food-producing species. Fera can accurately analyse samples, including poultry, game, red meat, offal and milk, for residues of drugs in the benzimidazole group to ensure that any of your food products do not breach the required regulatory limits.

Testing is carried out using liquid chromatography–tandem mass spectrometry (LC–MS/MS), and has been validated in accordance with the principles set out in Commission Decision 2002/657/EC, for the majority of analyte / matrix combinations. This analysis method is accredited to ISO17025 by the United Kingdom Accreditation Service (UKAS)

Veterinary Medicines Multi-Residue Screen (Option 2)

Within this multi-residue screen, Option 2, Fera food safety experts highlight the presence of over 70 veterinary medicines within one single screen. These analytes fall into the following main classes : Anthelmitics, Coccidiostats, and Sedatives.


β-Agonists (beta-agonists or Beta adrenergic agonists) are used in veterinary medicine to treat pulmonary disorders, but have also been used illegally as growth promoters for more efficient meat production. Fera’s food safety scientists can screen your food samples to check residue levels and confirm they are not present where not permitted, for example from use as illicit growth promoters in the EU.


The avermectins are a series of drugs used to treat parasitic worms. Fera food safety experts make use of innovative testing methods to highlight the levels of a comprehensive range of avermectins, within your food samples. We can also provide the evidence required by regulators to verify that the levels of avermectins within your food products are compliant.
