The U.S. Food and Drug Administration (FDA) is taking steps to reduce inorganic arsenic in infant rice cereal, a leading source of arsenic exposure in infants. Through a draft guidance to industry, the FDA is proposing a limit or “action level” of 100 parts per billion (ppb) for inorganic arsenic in infant rice cereal. This is parallel to the level set by the European Commission (EC) for rice intended for the production of food for infants and young children.
“Our actions are driven by our duty to protect the public health and our careful analysis of the data and the emerging science,” said Susan Mayne, director of the FDA’s Center for Food Safety and Applied Nutrition. “The proposed limit is a prudent and achievable step to reduce exposure to arsenic among infants.”
The proposed limit stems from extensive testing of rice and non-rice products, a 2016 FDA risk assessment that analyzed scientific studies showing an association between adverse pregnancy outcomes and neurological effects in early life with inorganic arsenic exposure, and an evaluation of the feasibility of reducing inorganic arsenic in infant rice cereal. The agency is releasing data showing the levels of inorganic arsenic in 76 samples of rice cereals for infants. Nearly half (47%) of infant rice cereals sampled from retail stores in 2014 met the agency’s proposed action level of 100 ppb inorganic arsenic and a large majority (78%) were at or below 110 ppb inorganic arsenic.
To assess if there were other sources of inorganic arsenic in infant foods, the FDA also tested more than 400 samples of other foods commonly eaten by infants and toddlers. The agency found all the non-rice foods to be well below 100 ppb inorganic arsenic.
The agency expects manufacturers can produce infant rice cereal that meet or are below the proposed limit with the use of good manufacturing practices, such as sourcing rice with lower inorganic arsenic levels.
The FDA is accepting public comments on the proposed action level and the risk assessment for 90 days.
