Document Summary

Microbes in foods: types, sources and factors affecting their growth. External sources that encountered during the process of production. Gi tract, urinogenital tract, respiratory tract of animals. Proper growth methods, damage reduction, quick washing, proper storage before and after processing. Many microbes in digestive, respiratory & urinogenital tract & on skin, hair, hooves and feathers. Fish carry microbes in their gills, scales and gi tract. Microbes carried on dust particles and moisture droplets. Many different types of microbes, numbers can be high (billions/g) Can contaminate water fish and crops, especially when used as fertilizer. Used in food production: irrigation of crops, drinking by animals, raising fish, washing foods. Effective husbandry, thorough cleansing removal of hair/feathers careful removal of digestive, urinogenital & respiratory organs, proper sanitation, proper food storage. Avoid the use of sewage as a fertilizer, use only properly treated sewage, wash foods well after harvesting. Use chlorine-treated (potable) water for processing, washing and sanitation.
