As well as accredited analyses for a range of matrices from food producing animals. Fera also provide bespoke method development solutions and un-accredited analyses for other analyte/matrix combinations. Processed meat and samples high in fat may present an analytical challenge and require additional method development prior to analysis and as such cannot always be analysed using accredited methodology. Please get in touch using the contact details on this page to confirm testing requirements and accreditation status if unsure.
Fera’s ISO 17025 accreditation status can be found at https://www.ukas.com/download-schedule/1642/Testing/.
Fera’s food safety experts use accredited analytical methods to detect and quantify quinolone and fluoroquinolone residues across a wide range of food matrices. Our analysis provides clear, defensible evidence to support regulatory compliance.
Quinolones are broad-spectrum antibiotics used to treat bacterial infections in many food-producing animals. While they offer important benefits for disease control, widespread use across the agri-food sector can increase the risk of consumer exposure to residues.
Residues of veterinary medicines may cause physiological effects in humans when consumed at elevated levels. This has created a need for sensitive analytical testing capable of detecting quinolones at trace concentrations in food.
Maximum Residue Limits (MRLs) for quinolones are defined in Commission Regulation (EU) 37/2010 for muscle, skin/fat, liver, kidney and milk in a range of food-producing species.
This screen includes the following compounds: Ciprofloxacin, Danofloxacin, Difloxacin, Enrofloxacin, Flumequine, Marbofloxacin, Nalidixic acid, Norfloxacin, Oxolinic acid and Sarafloxacin.
Fera can analyse poultry, game, red meat, offal, shellfish, fish, eggs, honey and milk to ensure your products do not breach regulatory limits for quinolone residues.
The analytical method is based on sample extraction using QuEChERS methodology, followed by liquid chromatography–tandem mass spectrometry (LC–MS/MS). Methods are validated in accordance with Commission Decision 2002/657/EC and accredited to ISO/IEC 17025 by the United Kingdom Accreditation Service (UKAS).
Multi-Residue Option
This test is available as a standalone analysis or as part of our broader veterinary medicines multi-residue screen.

Penicillins/CephalosporinsFera food scientists are able to highlight and quantify the levels of a range of penicillins and cephalosporins, within a variety of foodstuffs. We can also provide the evidence required by regulators to validate the levels of penicillins and cephalosporins within your food products.
Nonsteroidal anti-inflammatory drugs (NSAIDs)Nonsteroidal anti-inflammatory drugs (NSAIDs) are a drug class used in the treatment of colic and musculoskeletal disorders in horses, infectious diseases in cattle, and as an aid in the treatment of mastitis in sows and dairy cows.
MacrolidesFera scientists can analyse food samples to detect residues from macrolides (including lincosamides). We can also provide the evidence required by regulators to validate the levels of macrolides within your food products
Dyes ScreenThis package screen by Fera contains a comprehensive range of dyes which have been known to be illegally employed as topical fungicides or acaracides in aquaculture.
Coccidiostats (Multi-residue)Fera food scientists are able to highlight and quantify the levels of a range of coccidostats, within a variety of foodstuffs. We can also provide the evidence required by regulators to validate the levels of coccidostats within your food products.
β-agonistsβ-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.
