Invisible, heat‑stable, and hazardous: What cereulides mean for food safety
Food safety in Europe is currently under intense scrutiny. The reason lies in large-scale preventive recalls of infant formula and follow on milk products, which have sharpened awareness of risks that were previously underestimated. The trigger for these recalls is a heat stable toxin produced by the bacterium Bacillus cereus: cereulide. A compound capable of […]
