Question

botulism food poisoning is usually traced to: lead and copper in food tape worms or other parasites in food improperly processed canned food highly acidic foods

Explanation:

Botulism is caused by the bacterium Clostridium botulinum. This bacterium thrives in low - oxygen environments, such as improperly processed canned foods. Lead and copper poisoning are different types of metal toxicities. Tapeworms and other parasites cause parasitic infections, not botulism. Highly acidic foods are less likely to support the growth of Clostridium botulinum as it prefers more neutral - to - low - acid conditions.

Answer:

improperly processed canned food
