Which characteristic describes TCS foods?

• A. Low moisture and low protein
• B. Moist and contains protein
• C. Dried and flaky
• D. High fat content

Answer: (B)

TCS foods are foods that need time-temperature control because they can support rapid growth of pathogens when left at unsafe temperatures. The essential trait is that they are moist and contain protein, since water and protein provide the nutrients and environment bacteria need to multiply quickly. That’s why describing them as moist and containing protein is the best fit. Foods with low moisture or that are dried don’t offer the water activity pathogens rely on, and high fat content alone isn’t the defining factor for TCS status because moisture and protein drive microbial growth more directly.
