Impact of a modification of food regulation on cadmium exposure

- 0.6% of the French population is overexposed to cadmium.
- Main contributors to cadmium exposure are bread, bivalve mollusks and potatoes.
- Applying new maximum limits would not dramatically reduce cadmium exposure among the population.
- Acting on the level of contamination from environmental sources should be investigated to decrease cadmium exposure.

The 2nd French Total Diet Study demonstrated that 0.6% of adults and 14.9% of children exceeded the tolerable weekly intake set by EFSA. The overexposure of several consumers (adults and children) can be partially due to the high consumption of bread and dried bread products, of bivalve mollusks and of potatoes. Except for mollusks, these foods are the main contributors identified for the general population. On this basis, the French agency for food, environmental and occupational health and safety (ANSES) assessed whether a decrease of the European maximum limits in foodstuffs could significantly reduce the level of exposure of French consumers. Applying ML set at P90 of the main contributors would neither significantly reduce exposure levels to cadmium for the general population, nor the percentage of subjects exceeding the TWI. To reduce background consumer exposure to cadmium, actions to be taken include efforts on sources that are at the origin of the soil contamination and the efficacy of consumption recommendations.
