Question

how can a person contract salmonellosis?
drinking a glass of contaminated water
eating perishable unrefrigerated food
eating a contaminated low - acid canned good
eating food prepared by an unwashed handler

Explanation:

Salmonellosis is a food - borne illness. It is commonly contracted by consuming food contaminated with Salmonella bacteria. Eating food prepared by an unwashed handler can introduce Salmonella into the food. Drinking contaminated water is more associated with water - borne diseases like cholera or typhoid, not typically salmonellosis. Eating perishable unrefrigerated food can lead to spoilage by various bacteria but not specifically Salmonella as the main culprit in all cases. Eating a contaminated low - acid canned good may have other issues like botulism in some cases, and Salmonella is not the most common pathogen in this context.
