BS EN 15742 discusses animal feeding stuff. It details best practices for determining OCPs in animal feeding stuff to ensure the safety of animals.
BS EN 15742 specifies a gas chromatographic method with electron capture detection (ECD) for the determination of organochlorine pesticides (OCPs) in compound feeds and oil and fats.
BS EN 15742 method is applicable to animal compound feed, oils and fats and fish meals with a water content up to about 20 % by weight and oil/fatty samples containing residues of one or more of the following OCPs, toxaphene and some of their isomers and degradation products. These OCPs include aldrin, dieldrin, endrin, endosufan and hexachlorobenzene (HCB).
BS EN 15742 method is considered a screening method for the following OCPs. Additional in-house validation is required for validated data. These OCPs include chlordane, endosulfan-sulphate, delta-keto-endrin, heptachlor, photo-heptachlor, cis- and trans-nonachlor.
BS EN 15742 provides a limit of quantification (LOQ) for the mentioned OCPs of 5 μg/kg. However, 10 μg/kg applies for heptachlor, aldrin, endrin, dieldrin, and endosulfan.
BS EN 15742 on OCPs in animal feeding stuffs is applicable to:
Some pesticides such as OCPs can be traced back to humans by the food chain. Animal by-products such as milk and meat are often contaminated with residues of OCPs. These enter animal’s body through water, contaminated feed and food. It is critical to monitor the content of OCPs in animal feeds which can cause liver, kidney, nervous system and cancer in animals.
BS EN 15742 provides you guidance on gas chromatographic method for determining OCPs in animal feeding stuff. BS EN 15742 also ensures that you perform the method accurately by providing you with the step-by-step procedure for the method.
The guidance in BS EN 15742 enables you to identify OCP levels in your animal feed and regulate its presence in the feed.
