What factor significantly contributes to foodborne illness outbreaks?

Improper food storage methods are a significant contributor to foodborne illness outbreaks because they create an environment where harmful bacteria can thrive. When food is not stored at the correct temperatures or is left out for extended periods, it can lead to bacterial growth and contamination. For instance, perishable foods need to be kept refrigerated to prevent the proliferation of pathogens. Additionally, improper storage can result in cross-contamination, where bacteria from one food item spreads to others, increasing the risk of foodborne illnesses. Ensuring proper food storage practices are followed is essential for food safety and minimizing the risk of outbreaks.

Using plastic utensils, overcooking food, and using seasoned ingredients do not directly lead to foodborne illness outbreaks. While they may affect taste or presentation, they are not as pivotal as storage practices when it comes to hygiene and food safety.
