Our LC-MS methods are highly efficient, with over 350 pesticides included in analytical screening for a wide range of sample types.  Fera food safety experts can both identify (screen) and quantify residues within a food sample using state of the art LC-MS/MS equipment.  These data can be vital to managing your production processes, demonstrating that they are fit for purpose, and providing strong evidence to regulators and consumers about the safety of your food products and compliance with various regulations, including Maximum Residue Levels (MRLs).  The pesticides analysed in the LC-MS multi-residue screen include insecticides, fungicides, herbicides and plant growth regulators.

Many producers use pesticides as recommended but if pesticides are used incorrectly, for example by overuse or applying incorrect harvest intervals excessive residue levels can be found within foodstuffs This can have significant and potential harmful effects for consumers so strict regulations are enforced around the world to verify the safety of foodstuffs for consumers, as well as ensuring production processes are satisfactory with the correct use of pesticides.  Rigorous, ongoing safety assessments are undertaken by regulatory bodies to be sure that any pesticide residues remaining in food are not harmful to consumers and these lead to the setting of statutory Maximum Residue Levels (MRLs). The MRL is the maximum safe amount of a given residue likely to remain in food products when a pesticide has been used correctly, adhering to good agricultural practice (GAP). Compliance assures regulators and consumers that pesticides have been used correctly and in turn ensures that consumer exposure is minimised. 

As many commercial pesticides are a complex range of different chemicals, it is important to ensure that a wide range of pesticide residues are monitored for in your food samples.  Our fast turnaround times (1-10 working days) ensure that results are readily available and you can quickly address any potential issues should they be identified. 

Our analysis requires only a 100g sample of your foodstuffs to ensure accurate results, but a bigger sample (typically 1kg) may be required to comply with EU and Codex regulations.

Fera is the UK National Reference Laboratory for the analyses of pesticide residues with leading experts in the field carrying out tests to verify that food meets regulatory requirements and ensuring consumers are not exposed to unacceptable levels of pesticide residues.


Fera food safety experts can both identify (screen) and quantify Fipronil and metabolite residues within a food sample using state of the art LC-MS/MS equipment. We can offer this test in a range of food samples including eggs.


This procedure is for simultaneous analyses of propylenethiourea (PTU) and ethylenethiourea (ETU) in a wide range of sample matrices. The methodology both identifies (screen) and quantifies residues within your food sample using state of the art liquid chromatography tandem mass spectrometry (LC-MS/MS) equipment.
