Which of the following are common causes of foodborne illness in a restaurant and how can they be prevented?

• A. Improper temperature control, cross-contamination, poor hygiene, undercooking; prevent with HACCP, temperature monitoring, proper storage, sanitation, training
• B. Inconsistent lighting in the dining room
• C. Decorative napkins misprinted
• D. Slow service during peak hours

Answer: (A)

Preventing foodborne illness in a restaurant revolves around controlling hazards that can contaminate food and ensuring safe handling from receipt to service. The best answer highlights four common causes: improper temperature control, cross-contamination, poor hygiene, and undercooking. Each of these creates conditions for harmful microbes to survive or spread, so addressing them with practical safeguards is essential.

Improper temperature control allows bacteria to multiply or survive at unsafe levels. Keeping foods at correct temperatures through continuous temperature monitoring and timely cooking and cooling helps prevent growth. Cross-contamination occurs when pathogens move from one surface, utensil, or raw product to ready-to-eat food; implementing dedicated equipment, separate prep areas, and color-coded tools helps prevent this. Poor hygiene, including inadequate handwashing and dirty surfaces, directly introduces microbes into food, so strong sanitation practices, routine cleaning, and reliable staff hygiene training reduce risk. Underclooking foods can fail to destroy pathogens, so ensuring cooking temperatures are reached and validated is key.

HACCP, or Hazard Analysis and Critical Control Points, is a preventive system that guides restaurants to identify where hazards could occur in the flow of food and establish controls at those points—together with ongoing temperature monitoring, proper storage, sanitation, and training.

The other options don’t address these food safety risks. Inconsistent dining room lighting, decorative napkins misprinted, or slow service during peak hours do not directly cause foodborne illness or rely on the safety controls that prevent microbial hazards.
