Since human bodies may be part of the manufacturing process, a sterilization process must be effective enough to kill the pathogens on or in human bodies. Additionally, sterilization methods should not leave the manufacturing facility without damaging the product being manufactured.
To effectively kill the pathogens on or in the human body, sterilization methods use several approaches, including gas sterilization, high pressure steam, ethylene oxide (EO) gas, and liquid chemical sterilants. All of these sterilization methods, however, have various limitations. For example, steam sterilization involves the application of heat to a surface. The heat, however, may be conducted through the product being sterilized, damaging the product. Ethylene oxide gas, while a relatively benign gas, may react with other materials in the manufacturing process, creating toxic by-products. Liquid chemical sterilants, while effective in killing microbes, may leave the manufacturing facility with potentially hazardous chemicals. Furthermore, liquid chemical sterilants may use a number of potentially harmful chemicals, such as benzene.
Conventional sterilization methods thus create safety and environmental risks to both the manufacturer and the consumer of the products that are sterilized. The risks are particularly pronounced with a method such as steam sterilization, where heat may damage the product being sterilized. The risks also exist with some of the liquid chemical sterilants, since they may leave the manufacturing facility with potentially hazardous chemicals.
The risks presented by conventional sterilization methods to the manufacturer and the consumer are equally as significant in the food manufacturing industry. Food manufacturers may use steam to heat food products. The steam is directed against the surface of the food product, such as hamburger patties, and may damage the patty. Other food manufacturers may elect to use liquid chemical sterilants to kill pathogens on or in food products. These liquid chemical sterilants, however, may damage the food product, leaving chemical residues.
Another limitation of conventional sterilization methods is that they may be relatively ineffective in killing certain types of microorganisms. For example, bacterial spores are notoriously difficult to kill with conventional methods. The spore forms are extremely robust, and are resistant to a wide variety of sterilization techniques, including gas sterilization, steam sterilization, and liquid chemical
