Food Safety Certification Practice Test

Which of the following is NOT a characteristic of TCS foods?

1. High protein content

2. Water content

3. Low acidity

4. High sugar content

The correct answer is: High sugar content

TCS foods, or Time/Temperature Control for Safety foods, are defined by their potential to support the growth of pathogenic microorganisms if not stored properly. A key characteristic of TCS foods is their composition that provides an environment conducive to microbial growth. High protein content contributes to TCS classification because many bacteria thrive on protein, making foods like meat and dairy products more prone to spoilage and contamination. Likewise, high water content in foods offers moisture that microbes require for growth, which is another trait that TCS foods have. Low acidity is significant as well; most pathogens prefer a neutral or low-acid environment, which allows them to flourish, hence foods that fall under this category are generally low in acid. While high sugar content can affect the growth of certain microbes, it does not necessarily make a food TCS. Foods high in sugar, like jams or candies, often have lower moisture availability, which can inhibit microbial growth. Therefore, high sugar content is not a defining characteristic of TCS foods, making it the correct choice for this question.
