Final answer:
TCS foods are primarily at risk of biological hazards, including foodborne pathogens such as Salmonella, but they can also contain chemical contaminants like agrochemicals and environmental contaminants.
Step-by-step explanation:
The type of hazards associated with TCS foods (Time/Temperature Control for Safety foods) are primarily biological hazards, which include foodborne pathogens like bacteria, viruses, and parasites that can contaminate food and cause illness. Two major categories of chemical contaminants that can also be associated with TCS foods are agrochemicals and environmental contaminants. For example, foods can be contaminated with harmful bacteria such as Salmonella or E. coli, which have been involved in various outbreaks. The ingestion of raw or undercooked meat, dairy products, or other TCS foods contaminated with disease-causing bacteria or toxins can lead to foodborne illness. Furthermore, processed foods may contain additives and preservatives that can potentially be allergenic or linked to an increased cancer risk.
