Parents across the UK have been warned not to use a specific batch of Aptamil First Infant Formula after it was discovered to contain a toxin, cereulide, that can lead to serious health issues in infants. The recall, issued by the Food Standards Agency (FSA), affects one batch of the popular product, which is sold in 800g packs and has the expiry date of October 31, 2026. The affected batch is believed to pose a risk to babies due to potential vomiting and other digestive issues caused by cereulide, a toxin produced by bacteria that is resistant to heat and cooking.
This recall follows similar incidents where other large manufacturers, including Nestlé, issued global recalls of their infant formula products after similar contamination was detected. The ongoing investigation into the source of this toxin suggests that it may have come from a shared third-party supplier used by both companies. As a result, the FSA has urged parents to check the batch number on their products and return any affected items for a full refund.
Details of the Recall: Identifying the Affected Batch
The recall pertains specifically to one batch of Aptamil First Infant Formula, identified by the product code EXP 31-10-2026. This batch was sold between May and July 2025, and the toxin contamination was only recently discovered after a series of investigations by the FSA. Cereulide, the toxin found in the batch, is particularly concerning because it can survive the typical cooking process used to prepare infant formula. This means that even if the formula is properly prepared, the toxin could still remain harmful to babies.
The Food Standards Agency has emphasized that no other batches of Aptamil First Infant Formula are affected by this issue. Parents who have purchased the affected batch are advised to stop using it immediately and return it to the place of purchase, even if they do not have a receipt, for a full refund.
The Risk of Cereulide: Symptoms and Health Concerns
Cereulide is a toxin produced by the bacterium Bacillus cereus, which can be found in contaminated food, particularly in products that are improperly stored or handled. This toxin is known to cause food poisoning in humans, and for infants, the symptoms can develop rapidly after consumption. The FSA has outlined that the most common symptoms associated with cereulide poisoning include nausea, vomiting, and abdominal cramps. These symptoms can appear within hours of consuming the contaminated formula, and the impact on babies can be particularly severe due to their developing immune systems.
In severe cases, the toxin can cause more serious gastrointestinal distress, leading to dehydration and other complications. Since infants are particularly vulnerable to dehydration, it is critical that parents take immediate action if they suspect their baby has consumed the contaminated formula.
Danone’s Response: Investigations and Actions Taken
The issue was identified after Danone, the manufacturer of Aptamil, conducted an internal investigation into the source of the toxin. According to the FSA, the contamination originated from a third-party supplier, which provided ingredients used in the production of the affected batch of infant formula. Jodie Wild, the head of incidents at the FSA, explained, “Ongoing investigations have identified that the contamination originated from a shared third-party ingredient supplier. As a result of these investigations, Danone is recalling one batch of Aptamil product due to the presence of cereulide.”
Danone has taken immediate steps to recall the affected batch and work with the FSA to prevent further contamination. However, this incident raises broader concerns about the quality control measures in place for infant formula manufacturing, particularly when third-party suppliers are involved in the production process.
Similar Incidents: Nestlé and Other Manufacturers Affected
This is not the first time that a major infant formula manufacturer has been forced to recall products due to contamination concerns. Earlier in January 2026, Nestlé issued a global recall of specific batches of its own infant formula after similar contamination with cereulide was found. Like Danone, Nestlé traced the problem to a supplier providing an ingredient used in the production of its formula. The ingredient in question, arachidonic acid (ARA) oil, is commonly added to infant formula to mimic the beneficial properties of breast milk. However, the presence of cereulide in this ingredient led to the recall.
The FSA has indicated that the supplier responsible for the contaminated ARA oil has now been identified. This has prompted both Danone and Nestlé to review their supply chains and quality control processes to ensure that such incidents do not occur again. The FSA has also stated that they are working closely with manufacturers to trace all products that may have used ingredients from the implicated supplier and remove any affected products from sale.
Public Health Efforts: Monitoring and Preventive Measures
In response to these recalls, public health authorities, including the FSA, have been actively monitoring the situation and coordinating efforts to protect consumers. Parents who may have used the affected products are urged to contact their healthcare providers for advice, particularly if their child has shown any symptoms associated with cereulide poisoning. The FSA has advised that if any parents are concerned about the health of their infant after using the recalled formula, they should seek immediate medical attention.
The FSA’s proactive steps in investigating and addressing the issue are intended to prevent further harm and ensure the safety of infants consuming formula products. The agency has also called for greater transparency from manufacturers regarding their supply chains and ingredient sourcing to prevent similar contamination incidents in the future.
What Parents Should Do: Checking Labels and Returning Products
Parents who may have purchased the affected batch of Aptamil First Infant Formula are strongly advised to check the product packaging for the batch code EXP 31-10-2026. The product’s packaging will also list the expiry date, and consumers are urged to look for this information, which can be found on the lower back of the pack. If the affected batch is found, parents should return the product to the store where it was purchased for a full refund, even without a receipt.
The FSA has reiterated that only this specific batch is impacted, and no other batches of Aptamil or other Danone infant formulas are affected. Parents should also be cautious when purchasing infant formula from other brands and always ensure that the product is sourced from a trusted retailer with robust safety measures in place.
The Larger Picture: Infant Formula Safety and Consumer Trust
This recall, while concerning, underscores the ongoing challenges in ensuring the safety of products consumed by vulnerable populations such as infants. With the absence of effective treatments for cereulide poisoning, maintaining stringent quality control and transparent supply chains is essential to prevent future outbreaks. For parents, trust in the safety of infant formula products is paramount, and this incident highlights the importance of continued vigilance from both manufacturers and regulatory bodies in maintaining high standards of food safety.
As investigations into the source of contamination continue, it is clear that the recall process and the subsequent response by manufacturers will play a crucial role in restoring consumer confidence in infant formula products. Going forward, parents and health authorities alike will be watching closely to see how both Danone and Nestlé handle these challenges and whether further steps will be taken to ensure the safety of these essential products.
