STEC/VTEC in Food – Invisible Risk with High Relevance for Food Safety
Shiga toxin-producing Escherichia coli (STEC), also known as verotoxin-producing E. coli (VTEC), are among the most significant bacterial pathogens in the food sector. Even small amounts of these organisms can cause severe diseases in humans, ranging from diarrhea to life-threatening complications such as hemolytic uremic syndrome (HUS).
The pathogens naturally occur in the intestines of ruminants and can enter the food chain through various routes. STEC/VTEC are most commonly detected in raw or insufficiently heated beef, raw milk, raw milk products, and contaminated vegetables. Since the bacteria are neither visible nor detectable by taste, contamination remains unnoticed by consumers.
For manufacturers and distributors, consistent hygiene management along the entire production chain is crucial. In addition to avoiding cross-contamination, process controls, suitable heating methods, and regular microbiological testing play a central role in early detection and minimization of risks.
The BAV Institute supports companies with targeted microbiological analyses for STEC/VTEC and other pathogenic germs, thereby contributing to ensuring food safety and reliably meeting legal requirements.
