A recent investigation by Consumer Reports reveals that while some infant formulas are free from harmful heavy metals, others contain concerning levels of lead and arsenic, which can be harmful to babies.
Around 1 in 5 newborns in the U.S. rely entirely on formula, and by 6 months, 75% of babies incorporate it into their diet. Consumer Reports tested 41 types of powdered formulas, finding that 21 had little to no detectable heavy metals, including Enfamil Gentleease, Similac Advance, and Kirkland Signature ProCare from Costco.
However, the report also uncovered troubling results. Seven formulas contained inorganic arsenic, a carcinogen, while 18 tested positive for lead, which can harm brain development in babies. These contaminants are commonly found in food, water, and breast milk.
James Rogers, Ph.D., from Consumer Reports, emphasized that the presence of these metals in some formulas shows that it’s possible to create safer products. He called for manufacturers to improve testing of ingredients, packaging, and final products to reduce risks.
Consumer Reports reached out to infant formula manufacturers, with many affirming that they test their products for contaminants and consider them safe. Major brands, including Abbott Nutrition (Similac) and Mead Johnson (Enfamil), disputed the findings, emphasizing that trace amounts of heavy metals are not unique to formula.
Parents are advised to consult their pediatricians with concerns and to avoid making homemade formula. This investigation is part of Consumer Reports’ ongoing Toxic-Free Kids Food campaign, advocating for stricter safety measures to protect children from harmful substances in food.
