Overview of current meat hygiene and safety risks and summary of recent studies on biofilms,and control of Escherichia coli O157:H7 in nonintact,and Listeria monocytogenes in ready-to-eat,meat products

As meat consumption is increasing around the world, so do concerns and challenges to meat hygiene and safety. These concerns are mostly of a biological nature and include bacterial pathogens, such as Escherichia coli O157:H7, Salmonella and Campylobacter in raw meat and poultry, and Listeria monocytogenes in ready-to-eat processed products, while viral pathogens are of major concern at foodservice. A major goal of scientists, industry, public health and regulatory authorities is to control pathogenic microorganisms and improve meat product hygiene and safety within a country and internationally. This paper is not a comprehensive or critical review of the scientific literature on the broad area of meat hygiene and safety, but it provides an overview of major current meat hygiene and safety issues, and then a summary of studies on biofilm formation by pathogens, control of E. coli O157:H7 in nonintact meat products, and control of L. monocytogenes in ready-to-eat meat products, conducted at the Center for Meat Safety & Quality and Food Safety Cluster of Colorado State University in recent years.
