Formula Recall Expands after Testing Reveals Heat-Resistant Toxin

A batch of infant formula sold across the United States has been recalled after tests identified a toxin linked to foodborne illness. The product, intended for babies up to 12 months old, was distributed online and in retail stores. Health authorities stress that no illnesses have been confirmed so far, though the recall reflects wider international concerns about contamination in infant nutrition products.

The recall involves a2 Platinum Premium USA infant formula, produced by the a2 Milk Company. According to the U.S. Food and Drug Administration (FDA), three batches were withdrawn after the detection of cereulide, a toxin produced by certain strains of Bacillus cereus.

The affected formula was sold via the company’s website, Amazon, and Meijer stores. According to the FDA, around16,428 units reached consumers out of more than 63,000 units produced in the recalled batches.

Contamination Linked to Heat-Resistant Toxin

Cereulide is a toxin associated with food poisoning and is notable for its resistance to heat. According to the FDA, preparing infant formula with hot water does not neutralise the toxin, which remains active even after standard preparation methods.

Symptoms linked to cereulide exposure typically appear within 30 minutes to six hours after ingestion. These include nausea and vomiting, and in most cases resolve within 24 hours. Infants, due to their developing immune systems, face a higher risk of complications such as dehydration.

The recall was initiated after additional product testing identified the presence of the toxin. According to the company’s statement, this testing followed updated guidance issued by New Zealand’s food regulatory authority. The likely source of contamination has been traced to an ingredient used in the formula, though investigations remain ongoing.

Consumers have been advised to stop using the affected products immediately. According to the FDA, the formula should either be discarded or returned to the place of purchase for a refund.

Part of a Broader Global Food Safety Concern

The recall comes amid a wider pattern of international alerts involving cereulide contamination in infant formula. According to the World Health Organization (WHO), products linked to similar contamination have been distributed across 99 countries and territories since late 2025.

The WHO reports that 144 suspected and confirmed cases have been identified across ten countries, although only one country has confirmed cases through laboratory testing. The organisation notes that the overall public health risk is considered moderate, largely due to the vulnerability of infants and uncertainties around the full distribution of affected products.

Investigations have suggested that arachidonic acid oil, an ingredient used in some infant nutrition products, may be a common source of contamination. However, according to the WHO, full traceability and root cause analysis are still incomplete.

The U.S. recall is limited to products labelled for the American market and does not affect versions sold in other countries. According to the a2 Milk Company, the product had already been discontinued and removed from sale before the recall was formally announced. Authorities continue to monitor the situation while urging consumers to follow recall guidance. The absence of confirmed illnesses in this case does not alter the precautionary approach taken by regulators, particularly given the risks associated with infant exposure.
