What are the high risk populations for foodborne illness?
These high-risk populations include preschool-age children, elderly people, and people with compromised immune systems. Very young children are at a higher risk of getting a foodborne illness because they have not yet built up strong immune systems. As people age, changes occur in their organs.

Bacillus cereus.
How does cultural differences affect food safety?
This can create communication barriers. Cultural differences can influence how food handlers view food safety as well. Staff often have varying education levels. This can make teaching food safety to some of them more difficult. Illness-causing pathogens are being found on food that once was considered safe.
