Widespread microplastic contamination and heavy metal concerns in baby foods raise new safety questions

Consumer Reports uncovers pervasive microplastic presence and trace heavy metals in packaged baby foods, prompting calls for stricter standards amid growing concerns over child safety and packaging contamination.

Consumer Reports has found that most packaged baby foods it tested contained heavy metals below its own safety thresholds, but the group said the results still point to a wider contamination problem for families with very young children. In tests of 48 products from 11 brands, including cereals, purées, snacks, entrées and juice, the organisation said 96% were below its levels of concern for heavy metals, even though trace amounts of arsenic, cadmium and lead turned up in many samples. Mercury was rare by comparison, appearing in only a small share of products.

The findings were more troubling on other contaminants. Consumer Reports said phthalates, chemicals linked to plastics and packaging, were detected in most of the foods it examined, while microplastics were found in every purée it analysed for plastic particles. The particles ranged from 15 to 500 micrometres, and the testing covered products packaged in both plastic and glass, suggesting that the issue is not limited to one type of container. The group said these results reinforce concerns that contamination can enter food at several stages of production and packaging.

Consumer Reports said it used secret shoppers to buy two to four lots of each product before sending samples to an accredited third-party laboratory. It tested all 48 products for total arsenic, cadmium, lead, mercury, three bisphenols and 13 common phthalates, and then carried out additional work on samples with detectable arsenic to separate inorganic from organic forms. A smaller group of products was also screened for PFAS, often called “forever chemicals”, while the microplastics work focused on 15 purées and one juice. The organisation said its “levels of concern” were designed to estimate a child’s exposure from one serving, not to judge whether a product met regulatory limits.

Among the products that stood out, Consumer Reports said Gerber Rice Cereal averaged 63 parts per billion of inorganic arsenic, above its own benchmark but still below the Food and Drug Administration’s action level of 100 parts per billion for infant rice cereal. A Good & Gather fruit purée also exceeded the group’s arsenic threshold. Consumer Reports said PFAS did not top its limits in the subset it examined. The FDA, meanwhile, has been working through its Closer to Zero initiative, launched in 2021, to lower exposure to lead, arsenic, cadmium and mercury in foods for babies and young children.

The latest results arrive as states move ahead with their own rules on baby food transparency and testing. According to Consumer Reports, California, Maryland, Virginia and Illinois have all enacted requirements related to heavy metal testing or disclosure. The FDA has established action levels for some heavy metals, but it has not set a limit for microplastics in food, leaving parents with few clear standards for one of the newer concerns flagged by the testing. For caregivers, the message is less about one product category than about the broader challenge of limiting exposure during a stage of life when children are especially vulnerable.
