The Microbiology
of Meat and Poultry

edited by Andrew Davies

Microbiology of Meat and Poultry provides a critical review of the bacteria, yeasts and moulds that grow on, and can potentially spoil, meat and poultry products. Additionally, the effects of the interaction between microorganisms and the physical chemical changes found in meats are assessed.

The consequences of industrial slaughtering, processing and packaging of meat are analyzed and the consequent quality control and food safety issues are addressed. These practices, stemming from the commercial demands of developed countries, are contrasted to the methods of preserving meat in less developed countries.

Microbiology of Meat and Poultry provides essential information for industrial food scientists and technologists involved in the production and processing of meats as well as quality control in the meat industry and government agencies.
