Final answer:
Emotional is not a safety idea about food as food safety typically involves chemical, biological, and physical hazards.
Step-by-step explanation:
Among the following options, emotional is not a safety idea about food. When discussing food safety, the concerns typically revolve around chemical, biological, and physical hazards. Chemical hazards include contaminants like agrochemicals and environmental contaminants that can enter the food supply. Biological hazards are disease-causing agents like Norovirus and Salmonella. Physical hazards are foreign objects that can cause harm, such as metal shards or bone fragments. Emotional safety is not directly related to the safety of the food itself but rather to the psychological well-being of an individual, which is a separate concern.
