Which illness can be contracted from improper home canning methods?
botulism
e. coli infection
salmonellosis
gastroenteritis

The answer is A.

Explanation:

Botulism is a rare, possibly fatal illness linked to improperly canned or preserved foods. Symptoms include cramps, vomiting, breathing problems, difficulty swallowing, double vision, and weakness or paralysis

While E-coli is from unproperly done hamburger meat

Salmonellosis is normally from raw or underdone food such as chicken and eggs.

Gastroenteritis is from people who have not cleaned utensils or their hands and prepare your food.

I just studied all this so I can guarantee you the answer is A. However if you don't believe me look it up yourself. Thanks, Hope this helps! :)
