a2 Milk Company recalls three infant formula batches in USA

USA – The a2 Milk Company (“a2MC”) has voluntarily recalled three specific batches of its imported a2 Platinum Premium USA label infant formula 0-12 months (“Product”) due to the presence of cereulide. The Product is sold only in the United States.

The company stated that the issue is limited to the U.S.-label product and does not impact its infant formula sold in other markets, including Australia and Asia.

The recall, however, has impacted investor sentiment, with shares falling sharply amid concerns over brand trust, regulatory scrutiny, and potential spillover effects in key markets such as China, which accounts for a significant portion of the company’s revenue.

Cereulide is a heat-stable toxin produced by some strains of the bacterium Bacillus cereus. Illness occurs through the consumption of food contaminated with the toxin and preparing formula with hot water does not eliminate it.

Symptoms typically develop within 30 minutes to six hours of ingestion and most often involve gastrointestinal symptoms such as nausea and vomiting that typically self-resolve within 24 hours.

Infants are at greater risk due to their developing immune systems and can experience complications such as dehydration which require medical care.

The batch number and “Use By” (expiration) date are found on the bottom of each tin (refer to example below, together with image of product).

The Product was distributed nationally through a2MC’s website, Amazon and Meijer stores as part of Operation Fly Formula.

Importation rights expired on December 31st, 2025, and the Product has been discontinued and removed from sale prior to the initiation of the recall.

The total number of units in the three batches is 63,078 of which an estimated 16,428 units were sold to consumers.

The recall was initiated by a2MC after cereulide was detected through additional testing of the Product conducted in response to new guidance issued by New Zealand’s food regulatory authority. The probable source of cereulide is an ingredient in the Product.

The development highlights growing scrutiny in the global infant formula sector, where multiple recalls linked to contamination concerns have emerged in 2026, underscoring the critical importance of stringent quality control, supply chain integrity, and consumer safety in high-risk dairy categories.
