Restaurant and Staff Characteristics Related to Practices that Could Contribute to Cross-Contamination

Area of Science:

• Food Safety
• Public Health
• Environmental Health

Background:

• Foodborne illness is a significant public health issue in the U.S., with numerous outbreaks annually.
• Restaurants are implicated in the majority of foodborne illness outbreaks, often due to food contamination during preparation and storage.

Purpose of the Study:

• To identify restaurant characteristics, policies, and practices linked to food contamination prevention.
• To analyze factors contributing to foodborne pathogen contamination in restaurant settings.

Main Methods:

• Data collected through manager interviews and kitchen observations in 312 restaurants across six Centers for Disease Control and Prevention (CDC) Environmental Health Specialists Network (EHS-Net) sites.
• Observed food worker actions that could lead to contamination were recorded and analyzed.

Main Results:

• A significant percentage of restaurants (63.1%) had observed food worker actions potentially leading to contamination.
• Bare-hand or dirty glove contact with ready-to-eat food was the most frequent contamination risk observed (35.9%).
• Independent restaurants, those without certified managers or trained staff, and those lacking specific hygiene policies showed higher rates of potential contamination actions.

Conclusions:

• Strong food safety training and policies, particularly for hand hygiene and minimizing bare-hand contact, are crucial for preventing contamination.
• Interventions should be targeted towards independent restaurants, which appear to have higher risks.
• Supporting manager certification and comprehensive worker training can improve food safety practices in the foodservice industry.
