Much of the blame for the spread of the virus across the world has been placed on wild birds. Because poultry on free range and backyard farms could potentially come into contact with wild birds or their droppings, these farming types are an obvious target for blame. Many countries have periodically ordered their free range flocks indoors - among them France, Germany, the Netherlands, Sweden, Slovenia, and parts of Canada and Norway. A further intensification of the poultry industry has been put forward as the solution to the problem, on the rationale that keeping birds indoors in confined. | Rev. sci. tech. Off. int. Epiz. 2000 19 2 376-395 Campylobacter infection of commercial poultry . Shane Department of Epidemiology and Community Health School of Veterinary Medicine Louisiana State University Baton Rouge Louisiana 70803 United States of America Summary Campylobacter jejuni a widespread food-borne pathogen is responsible for enteritis in the populations of both industrialised and developing nations and is acquired by consumption of contaminated water milk and food products. Contaminated poultry meat is regarded as an important source of campylobacteriosis with both commercial broiler and turkey growing flocks infected at two to three weeks of age by direct and indirect horizontal exposure. Non-chlorinated water is regarded as a vehicle of infection followed by rapid intraflock dissemination. Intensification in the poultry industry has contributed to the increased prevalence rates on carcasses associated with increased stocking density and mechanised processing which are inherent to the high efficiency dictated by a competitive market. Currently pre- and post-harvest control measures may ameliorate the problem of Campylobacter infection in consumers. Refrigerated storage and transport of red meat and poultry appropriate handling and food preparation and thorough cooking reduce the possibility of food-borne infection. In view of the world-wide distribution of c. jejuni infection and the multiplicity of sources including non-pasteurised milk and contaminated water it is inappropriate to impose trade restrictions on poultry meat based on the detection of Campylobacters.
