Using
monoclonal antibodies in a lateral-flow device
to detect botulinum toxins isn’t new but it is believed to be the first that can concurrently detect and differentiate the A and B serotypes. The gold standard of detection of BoNTs is the mouse bioassay, which can detect 10 pg/mL of toxin.

How common is botulism in canned food?
Home-canned vegetables are the most common cause of botulism outbreaks in the United States. From 1996 to 2014, there were
210 outbreaks
of foodborne botulism reported to CDC. Of the 145 outbreaks that were caused by home-prepared foods, 43 outbreaks, or 30%, were from home-canned vegetables.
What foods can contain botulism?
