Understanding the Silent Threat in Food - Cereulide
28 Apr 2026
Introduction
The recall of certain batches of infant formula products in early 2026 served as a timely reminder of the importance of vigilance against cereulide, a toxin produced by certain strains of Bacillus cereus (B. cereus). The incident highlighted that even in controlled manufacturing environments, food safety risks can emerge, reinforcing the need for robust preventive measures. This is especially so for products consumed by vulnerable groups such as infants. So, what exactly is cereulide, and why is it important to prevent its formation in food?
What is Cereulide?
Cereulide is a heat-stable toxin produced by certain strains of B. cereus, a bacterium that is commonly found in the environment. When these bacteria proliferate to high levels, they may produce toxins that could cause us to fall sick. What makes cereulide particularly concerning is that it has no smell or taste, so contaminated food may have a completely normal appearance.
