Which pathogens are commonly associated with foodborne illness?

• A. Salmonella, E. coli, botulism, and listeriosis
• B. Influenza, rhinovirus, Salmonella, and E. coli
• C. Bacillus, streptococcus, norovirus, and rotavirus
• D. Campylobacter, Shigella, Giardia, and Norovirus

Answer: (A)

Foodborne illness is most strongly associated with a core group of pathogens that are routinely linked to outbreaks from contaminated foods. Salmonella and pathogenic E. coli are two of the leading bacterial culprits you’ll see in many foods, from poultry and eggs to fresh produce, causing gastroenteritis and more severe illness in some people. Listeria monocytogenes is especially notable because it can grow at refrigerator temperatures and contaminate ready-to-eat foods like deli meats and soft cheeses, leading to serious illness in pregnant people, newborns, and older adults. Botulism represents toxin-mediated illness from Clostridium botulinum, tied to improperly canned or preserved foods, and it is known for its potential severity; prevention hinges on proper canning, storage, and heating. The other options mix in organisms or disease names that aren’t as representative of the foodsafety threat. Some involve respiratory viruses that aren’t typically spread by food, and others include organisms that are less central to routine foodborne outbreaks, making them a poorer match for the common foodborne pathogen picture.
