In food processing, pasteurization (also pasteurisation) is a process of food preservation in which packaged foods (e.g., milk and fruit juices) are treated with mild heat, usually to less than 100 °C (212 °F), to eliminate pathogens and extend shelf life.
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. [1] Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life.

The international Radura logo, used to show a food has been treated with ionizing radiation. A portable, trailer-mounted food irradiation machine, c. 1968 Food irradiation (sometimes American English: radurization; British English: radurisation) is the process of exposing food and food packaging to ionizing radiation, such as from gamma rays, x-rays, or electron beams.
In theory, food poisoning [7] is 100% preventable. However this cannot be achieved due to the number of persons involved in the supply chain, [8] as well as the fact that pathogens can be introduced into foods no matter how many precautions are taken. [9] [contradictory]
Microorganisms growing on an agar plate. Sterilization (British English: sterilisation) refers to any process that removes, kills, or deactivates all forms of life (particularly microorganisms such as fungi, bacteria, spores, and unicellular eukaryotic organisms) and other biological agents (such as prions or viruses) present in fluid or on a specific surface or object.

Salmonella is notorious for its ability to survive desiccation and can persist for years in dry environments and foods. [32] The bacteria are not destroyed by freezing, [33] [34] but UV light and heat accelerate their destruction.
Chemical Structure of Triton X-100 (n = 9-10). This process has many of the advantages of the "traditional" removal techniques. This process does not denature proteins, because the detergents only affect lipids and lipid derivatives. There is a 100% viral death achieved by this process and the equipment is relatively simple and easy to use.
