The A2 Milk Company has announced a voluntary recall of over 63,000 containers of its A2 Platinum infant formula after three batches were found to have been contaminated with cereulide, a bacterial toxin. Though cereulide bacterial contamination is rare in infant formula, ingestion of the bacteria can cause gastrointestinal symptoms in babies, such as nausea and vomiting, which can lead to dehydration. Symptoms typically resolve on their own within 24 hours, the Food and Drug Administration says. At this time, no confirmed illnesses have been reported.

If you have any cans of A2 Platinum infant formula, check them against the batch numbers and expiration dates listed below, and do not use the product. If your infant is showing signs of vomiting, nausea, or dehydration, reach out to your child’s pediatrician for further guidance. It’s important to switch your baby’s formula to another brand right away.

More on Baby Formula Safety

A2 Platinum infant formula is sold only in the U.S., but is produced in New Zealand. According to the FDA recall announcement, “[t]he recall was initiated by a2MC [the A2 Milk Company] 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 recall comes after multiple countries across Europe and Asia have recalled numerous batches of infant formula due to cereulide contamination between December 2025 and February 2026. In March 2026, the World Health Organization reported the source of that contamination was arachidonic acid (ARA) oil, which is used as a source of omega-6 fatty acids in infant formula.

When CR asked the A2 Milk Company if the source of the cereulide toxin contamination in A2 Platinum is related to ARA oil, a company spokesperson said that the matter is still being investigated. 

A spokesperson for the A2 Milk Company told CR that when the cereulide contamination issue was identified, they did a risk assessment of the company’s existing products, including extensive product testing. “Following the release of updated guidance from the New Zealand food regulator (country of manufacture) on 15 April 2026, we completed retrospective testing of further batches under different testing measures. The test results for the recalled batches exceeded the new guidance,” the spokesperson said. 

What to Know About Cereulide

The cereulide toxin can be produced by vegetative cells of the bacterium Bacillus cereus, whose spores are found worldwide and can easily spread through dust or soil. Cereulide is highly heat-resistant and not inactivated by boiling water, so preparing infant formula with hot water won’t eliminate the toxin. Bacillus cereus spores can also be present in dry powdered infant formula and germinate when the powder is dissolved in water and left to sit for several hours at room temperature. 

If a baby ingests the cereulide toxin, it can cause nausea and vomiting within 30 minutes to 6 hours, which usually resolves on its own within 24 hours. But the infection can be severe in infants and lead to dehydration, especially with repeated feedings, which is why it’s important to seek medical attention if you notice your infant is vomiting, which differs from typical spit-up. 

Cereulide and B. cereus are not routinely tested for in infant formula, the WHO says.

The bacteria can multiply and form the cereulide toxin if infant formula powder is dissolved in water and stored at room temperature for several hours. That’s why it’s important to prepare infant formula right before offering it to your baby, BfR, the German Federal Institute for Risk Assessment says, and don’t let a bottle sit out for more than 2 hours. The Centers for Disease Control and Prevention also recommends using prepared infant formula within 2 hours of preparation and within 1 hour of feeding to prevent spoilage.
