Where can Campylobacter bacteria be found?

Campylobacter bacteria are often associated with foodborne illnesses, and they are primarily found in certain animal products and environments. The correct answer highlights that Campylobacter can commonly be located in pets, raw milk, and raw poultry.

Raw poultry is particularly prone to contamination because these bacteria are part of the normal flora in the intestines of healthy birds. Additionally, outbreaks of Campylobacter infections have been linked to consumption of unpasteurized milk, as it can carry bacteria that are harmful if ingested. Pets, especially cats and dogs, can also harbor Campylobacter, contributing to transmission to humans through direct contact or fecal contamination.

The other answer choices do not typically contain Campylobacter. For example, frozen vegetables are generally safe, as the freezing process does not allow for the bacteria to proliferate. Canned foods are subjected to high-temperature processes during canning, which effectively eliminate harmful microorganisms. Cooked meats should also be safe from Campylobacter, as proper cooking kills the bacteria. Therefore, the correct answer emphasizes the environments and food sources where Campylobacter is most likely to be found, reinforcing the importance of safe food handling practices.
