HUMAN NUTRITION

Detailed explanation-1: -Food poisoning occurs when sufficient numbers of particular types of bacteria, or their toxins, are present in the food you eat. These bacteria are called pathogens.

Detailed explanation-2: -Food manufacturers must do everything possible to avoid contamination and produce safe products, knowing the dramatic consequences if they don’t. There are four types of food contamination: physical, biological, chemical and allergenic.

Detailed explanation-3: -Microbes can be transferred from one food to another by using the same knife, cutting board or other utensil without washing the surface or utensil in between uses. A food that is fully cooked can become re-contaminated if it touches other raw foods or drippings from raw foods that contain pathogens.
