In Spain, eight infants have suffered vomiting and gastrointestinal problems after consuming certain baby formulas that are now being investigated for possible contamination with the toxin cereulide. Out of these cases, five babies required hospitalization, as reported by the European Centre for Disease Prevention and Control (ECDC) in its alert bulletin and by El País. Although laboratory studies have not confirmed the cause of the vomiting, it has been found that the affected infants consumed products that might have been contaminated.

Since December 2025, various lots of baby formulas from different brands have been proactively withdrawn from the market following the detection of cereulide in some samples. The toxin cereulide is known to cause nausea, stomach pain, and vomiting, posing a risk of dehydration in children. Typically, the negative effects of cereulide are low to moderate, but the severity can vary significantly depending on the age and health of the child, making younger infants particularly vulnerable.

This situation highlights concerns surrounding food safety standards in baby formula production and the need for rigorous monitoring to prevent such contamination incidents. As investigations continue, further measures may be required to ensure public health and restore confidence among parents regarding the safety of baby food products.
