Clostridium botulinum is dangerous because it produces a deadly toxin under which conditions?
a.In anaerobic (oxygen-free) environments such as improperly canned or ROP foods
b.Only in high-acid foods like lemon juice

d.Only in dry, low-moisture foods
解析
Clostridium botulinum grows and forms toxin in anaerobic, low-acid, moist environments such as improperly home-canned foods, ROP (reduced-oxygen packaged) foods, and garlic-in-oil mixtures. Oxygen and high acidity inhibit it, and it does not thrive in dry foods. The toxin attacks the nervous system.
