This involves evaluating food and making physical analysis of the structure, appearance, chromatography of the food, including food dyes, size, and shape of the food. For example, physical tests may confirm variation in food grains or infestation by insects in foods packed in bags.
Chemical testing analyzes the chemical constituents of foods as well as any nutrient content, acidity, moisture content, and if there is any poisonous component such as heavy metals, toxins, or chemicals produced in food processing.
This testing determines the existence of pathogens that are potentially dangerous to human beings, including bacteria (Salmonella, E. coli), viruses, or fungi, which cause foodborne diseases. Proper microbiological safety provides precautionary services for the well-being of the whole populace
