PFASs are known to accumulate in the body and stay for long periods of time. Extensive testing measures highlight the risks associated with ongoing, significant exposure to PFASs, which can result in liver, kidney, and thyroid effects, as well as changes in cholesterol. All of which can prove harmful to consumers.

Fera food safety experts can highlight the presence and levels of Perfluoroalkyl Substances (PFASs) within your food samples. Our experienced team make use of extensive industry experience to provide the relevant insights required for key business decisions and together with our fast turnaround times you can ensure your samples are safe to offer consumers and comply with relevant regulations.

PFASs are a range of synthetic chemical compounds, which are used across a range of industries because of their waterproofing, greaseproofing and stain repellent properties. Within the food sector they are extensively used on cookware and other equipment that are regularly in contact with food, which can result in increased exposure to these potentially harmful contaminants. Other areas of potential exposure include contamination of soil and water used to grow food, food packaging, and the equipment used to process food. The use of extensive testing is invaluable when highlighting, and addressing, high levels of PFASs within your production processes.

Fera’s extensive analysis methods can prove invaluable to avoid potentially costly product recalls, refusal and loss of customer trust. As a result our accurate methods are best utilised within an ongoing due diligence testing regime, to safeguard your business against these regulatory risks.

Through Feras LC-MS analysis methods, accurate and detailed insights into the levels of these PFASs can be obtained. This can result in a range of improvements within your production processes, to ensure only safe products are offered to your customers.

Turnaround and Reporting

Our swift 15 working day turnaround results in the valuable insights into your food samples being able to be acted upon quickly to achieve maximum benefits to your production and supply chain processes.

Our methods require only 50-100g per sample to provide the accuracy required while maintaining a low impact on your production processes. This can unlock the ability for ongoing due diligence testing, to be sure of your regulatory compliance and product safety within an ever changing regulatory landscape.

NRL Status

We are at the forefront of PDBE and other dioxin compounds analysis. As a result we hold NRL status for dioxins in both food and feed in the UK. We work regularly with legislative bodies to highlight trends within dioxins and ensure current analysis measures are fit for purpose within ever changing testing environments.

Ethyl carbamate (urethane)

Ethyl carbamate (EC), sometimes called urethane, is a naturally occurring compound in fermented foods and alcoholic beverages, and a known carcinogen. In many cases ethyl carbamate is formed by the reaction between cyanate and ethanol, though this is not the only means by which it forms.


Using GC-MS methods, Fera’s food safety experts can analyse your samples to detect traces of furan, a colourless, flammable, and highly volatile substance most frequently formed during thermal processing of foods. Fera testing procedure can accurately identify and quantify furan in your food samples to a target level of detection (LOD) of 2 - 5 µg/kg.
