As is well known, animals may be contaminated or are asymptomatic carriers of pathogenic bacteria and, thus, serve as sources of subsequent meat contamination or contamination of other food commodities through contaminated manure, soil and water. Microbial contaminants, especially pathogenic bacteria of enteric origin such as Escherichia coli O157: H7, Salmonella and Campylobacter, are of major concern because they can compromise food safety. Thus, there is a need to control pathogenic micro-organisms in animals, their products and other foods in order to enhance the safety of our food supply. Progress has been made in developing interventions for pathogen control following harvest of animals and plant products, but pre-harvest pathogen control in animals has major constraints. Approaches to pathogen control should be based on results of risk analysis activities. For example, pathogen control at the pre-harvest level should consider the results of research addressing pathogen ecology and risk analysis of animal management, handling, feeding, and shipping for slaughter practices. It is also important to realize that control or management of food safety risks should be based on an integrated effort and approach that addresses all sectors, from the producer through the processor, distributor, packer, retailer, food service worker and consumer. Nevertheless, reduction of pre-harvest pathogen prevalence may lead to a reduced probability that errors occurring in subsequent parts of the food chain will lead to foodborne illness. Overall, however, areas of emphasis for pathogen control and extent of efforts and resources committed to such control should be based on risk assessments and establishment of food safety objectives (FSO). This report examines these issues and presents an overview of related knowledge.
