Luxembourg Strengthens Controls Following Global Recall of Infant Milk Products for Bacillus cereus Toxin

Since January 6, 2026, Luxembourg participated in a large-scale recall of 50 infant milk products from various brands after an ingredient used in their manufacture—an oil rich in arachidonic acid (ARA), an omega-6 fatty acid labeled as Mortierella alpina oil—was found to be contaminated with cereulide, a toxin produced by the bacterium Bacillus cereus that can cause nausea, vomiting, and abdominal pain between 30 minutes and 6 hours after consumption. To ensure a high level of consumer protection and a harmonized approach among European authorities, laboratory analysis methods were refined and EFSA published guidance with stricter toxicological dose limits for risk assessment, which triggered a second wave of recalls in early February to comply with this new European risk evaluation. Of 30 samples of infant milk available in Luxembourg that were analyzed, only one tested positive for the toxin. To date, no confirmed cases of infant illness linked to consumption of affected products have been reported in Luxembourg.

That the contamination originated in a specific ingredient—a functional oil from a microscopic fungus, used to enrich infant milk with arachidonic acid—and not in the base milk powder itself confirms that the growing complexity of infant food formulation, incorporating functional ingredients from multiple specialized suppliers, multiplies possible entry points for contamination that no control focused exclusively on dairy raw materials could detect. That EFSA adjusted its toxicological criteria midway through the recall process, generating a second wave of corrective actions, further reflects how risk assessment of the same toxin can evolve within weeks when available scientific evidence is still being consolidated.

For TAAG, an event that required strengthened controls in Luxembourg despite only one of 30 samples analyzed in the country testing positive confirms the importance of applying the precautionary principle in the infant nutrition industry, the food segment with the lowest tolerance for microbiological risk: when the exposed population is infants, neither a low positivity rate nor the absence of confirmed clinical cases justify relaxing surveillance over imported functional ingredients from specialized suppliers.
