A new 2024 PT for the control of Chlorates and Perchlorates in infant milk

In 2020, new limits were set for the presence of chlorates and perchlorates in different types of food (COMMISSION REGULATION (EU) 2020/749 and COMMISSION REGULATION (EU) 2020/685)
As previously highlighted by EFSA (European Food Safety Authority), chlorates and perchlorates can both have an adverse effect on human health, in particular, they can reduce iodine uptake by the thyroid gland, causing reduced production of thyroid hormones and hypothyroidism.

The presence of chlorate (ClO3-) in food may result from the use of water treated with chlorine or from the use of disinfectants containing chlorine. The risk of contamination affects all foods that are frequently washed (such as fruit and vegetables) but also foods such as milk and its derivatives, fish and meat. In fact, chlorate enters raw milk as a disinfectant by-product, through contact of milk with chlorinated water or as a residue of cleaning chemicals on equipment surfaces.

Although an MRL for chlorate in foodstuffs has been set in the European Union (0,10 mg/kg in the specific case of milk) and the use of chlorate as a pesticide is banned, the treatment of water with chlorine and chlorine-based disinfectants is still permitted for use on farms and in fed plants.

As for perchlorate (ClO4-), this is a contaminant released into the environment by both natural processes and human action. Possible sources of contamination in food can be irrigation water, soil and fertiliser use. The MRL for perchlorate in baby food has been set at 0,02mg/kg.
