[Effect of premortal stress on the endogenous microbial contamination of broiler carcasses].
A study was undertaken to determine the interrelation between premortal stress and endogenic contamination. In 370 broilers the influence of transport, of a 48-h rest period and of an additional heat stress on the bacterial translocation was investigated. Even the normal transportation caused a contamination rate of nearly 50 per cent. 10 per cent of the transported animals suffered from a bacteriaemia induced by stress. The control group showed a significantly lower contamination rate. The rest time reduced the frequency of contamination. Heat stress did not have an influence on the contamination rate. The conclusion is that stress is aggravating the microbial risk for the consumer of poultry meat. Further research is necessary for characterizing the process of endogenic contamination.
