Microbiology of the food chain. Polymerase chain reaction (PCR) for the detection of food-borne pathogens. Detection of botulinum type A, B, E and F neurotoxin-producing clostridia1 Scope This Technical Specification specifies a horizontal method for the molecular detection of clostridia carrying botulinum neurotoxin A, B, E, and F genes by a PCR method. This method detects the genes and not the toxins, therefore a positive result does not necessarily mean the presence of these toxins in the sample investigated. This Technical Specification is applicable to products for human consumption, animal feed, and environmental samples.
