Prevalence, attachment ability and strength of the biological control agent Bacillus thuringiensis on tomato

Bacillus thuringiensis (Bt) is commonly used as a biological control agent (BCA) to control insect pests in edible plant production and can as such be introduced into the food chain of fresh produce. Using standard food di-agnostics Bt will be detected and reported as presumptive B. cereus.
