Chlorate is the salt of chloric acid. It is released as a by-product when disinfectants are used and when drinking water is treated, causing residues of chlorate to appear in food. Repeated ingestion of chlorate can lead to inhibited iodine absorption in humans, which can have health effects, especially for risk groups such as thyroid patients, newborns and children.
Residues of chlorate are frequently found in frozen vegetables, fruit juices and salads. It occurs as a result of glazing frozen vegetables, diluting concentrates for juice, and washing processes with chlorinated water.
The Annex to Regulation (EU) 2020/749 sets out the binding maximum residue levels for individual product groups. For example, the following MRLs apply:
- Citrus fruit, pome fruit, stone fruit: 0.05 mg/kg chlorate
- Nuts: 0,1 mg/kg chlorate
- Garlic, cultivated and wild mushrooms: 0,7 mg/kg chlorate
- Legumes: 0,35 mg/kg chlorate
- Spices: 0,07 mg/kg chlorate
Perchlorate is the salt of perchloric acid. It can also be introduced into foodstuffs as a by-product of disinfectants and leads to an inhibited absorption of iodine.
The new maximum residue levels (MRLs) for perchlorate are as follows::
- Fruits and vegetables: 0.05 mg/kg perchlorate
- This excludes Cucurbitaceae and kale with 0,10 mg/kg perchlorate, and leafy vegetables and fresh herbs with 0,50 mg/kg perchlorate
- Herbal and fruit tea: 0,75 mg/kg perchlorate
- Infant formulae, follow-on formulae, foods for special medical purposes for infants and young children and food for infants: 0,01 mg/kg perchlorate
- Baby food: 0,02 mg/kg perchlorate
- Processed cereal-based foods: 0,01 mg/kg perchlorate
