What is the moisture level in most TCS foods, represented in Aw (water activity) scale?

0.5-0.7
0.7-0.85
Greater than 0.85
0.95-1.0

The correct answer is: Greater than 0.85

The moisture level in most Time/Temperature Control for Safety (TCS) foods is indeed represented by a water activity (Aw) scale that is greater than 0.85. TCS foods are those that are more susceptible to bacterial growth because they provide an environment that is conducive to the proliferation of pathogens. The water activity scale measures the availability of water in a food product for microbial use, and an Aw value greater than 0.85 indicates that there is enough moisture present for harmful bacteria to thrive. Such foods include dairy products, meats, cooked rice, and cut fruits, which typically have high moisture content. Understanding this concept is essential for food safety as it guides food handlers to recognize which foods require stricter control measures to prevent foodborne illnesses associated with bacterial growth. The other ranges of the Aw scale indicated in the other choices do not provide a sufficient moisture level for bacterial growth, making them less relevant in the context of TCS foods.
