Our dioxins testing services

Fera food safety experts are able to establish the levels of a range of Dioxins and PCBs within your food sample as part of a complete overview of the safety of your foodstuffs. Our accredited methods of analysis are important to confirm that levels of these potentially harmful chemicals within your foodstuffs are below legislative limits thus avoiding potentially damaging product recalls, refusals, and loss of customer trust. With this analysis, our food safety experts can measure the levels of both dioxin like and non-dioxin like PCBs in your food samples.
