Which of the following is a TCS food?

• A. Fresh apples
• B. Dried beans
• C. Milk and dairy products
• D. Grains

Answer: (C)

TCS foods are those that can support rapid growth of harmful bacteria if not kept at proper temperatures, so they require careful time-temperature control. Milk and dairy products are classic TCS foods because they are highly perishable and provide moisture and nutrients that allow bacteria to multiply quickly when they’re not refrigerated or kept hot. Fresh apples are generally not treated as TCS in normal handling because they’re relatively shelf-stable at room temperature. Dried beans and grains are also not considered TCS in their dry state since their low moisture content inhibits rapid microbial growth; they become a TCS item mainly after cooking and holding at unsafe temperatures. So milk and dairy products clearly fit the TCS category.
