EFSA has set a new safety threshold for the main perfluoroalkyl substances, or PFAS, that accumulate in the body. The threshold – a group tolerable weekly intake (TWI) of 4.4 nanograms per kilogram of body weight per week – is part of a scientific opinion on the risks to human health arising from the presence of these substances in food.
The four PFAS that EFSA’s assessment focused on are perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS).
