Background and Summary

Minimising the amount of dirt on beef cattle offered for slaughter is considered to be of paramount importance in reducing the risk of bacterial contamination of beef carcasses. 

The limited available information would suggest that the amount of dirt on cattle is influenced by a wide range of feeding, environmental and management factors. The objectives of this project are to examine the relative importance of various dietary and other factors such as housing type, stocking density, ventilation and management on Northern Ireland farms on the dirtiness of beef cattle. The project would also examine the relationship between the dirtiness of cattle (or type of dirt) and bacterial contamination of carcasses.



This project would provide information, which should enable the incidence of dirty cattle to be reduced and thereby reduce the number of cattle rejected for slaughter because they are dirty. It would also provide the industry with information on the relationship between the dirtiness of cattle and bacterial contamination of beef carcasses.
