Dayton Webb · Answer 1

it is an exotoxic pathogen

Explanation:

The toxin which is released by the bacteria outside the cell is called exotoxin. Endotoxin is related with the lipopolysaccharide cell wall of gram-negative bacterial mostly.

Clostridium botulinum is the bacteria that produces clostridial toxin outside the cell and it causes foodborne intoxication in humans. This toxication is called botulism. Exotoxins are more lethal than endotoxin because it is very harmful even in a small dose.

Mostly the exotoxin is already present in the contaminated food and clostridium botulinum is mainly found in canned food.
