What is one of the main causes of foodborne illnesses?

Insufficient cooking temperatures is a primary cause of foodborne illnesses because cooking food to the appropriate internal temperature is essential for killing harmful pathogens, such as bacteria and viruses, that can contaminate food. Different types of food have specific temperature guidelines that must be met to ensure that they are safe for consumption. For example, poultry needs to reach an internal temperature of 165°F (74°C) to effectively eliminate harmful bacteria like Salmonella and Campylobacter. Undercooking food allows these pathogens to survive and potentially cause illness when the food is consumed.

The other choices do not directly lead to foodborne illnesses in the same manner. Serving food too quickly generally does not affect food safety, using trendy ingredients does not inherently increase foodborne illness risk, and cooking in bulk can be safe if proper temperature controls are maintained throughout the process. The key to preventing foodborne illness remains ensuring all food is cooked thoroughly.
