ELISA 1-2 days Inoculated beans and mushrooms
8 h Toxin potency testing in the medical industry

What detection techniques they used to detect C botulinum and its toxin in either human specimens or contaminated food products?

In vivo mouse lethality bioassay (MLB) is routinely used standard method to detect and confirm the presence of BoNTs in clinical specimen and food or environmental samples linked to botulism outbreaks.
