On Farm Food Safety Interventions

The farm or feedlot is the origin of micro-organisms introduced onto carcasses during slaughter and dressing. During rearing, numerous factors interact to affect the visual cleanliness and pathogen shedding characteristics of livestock. Age, coat length, clipping, journey time, feeding and abattoir have been found to influence coat cleanliness, while in Britain sex, breed, transport vehicle floor type, transport vehicle dirtiness and housing prior to transport were not significantly related to visual cleanliness of cattle. A lot of interest has been taken in the effects of modifying the diet or feeding probiotics to animals to reduce shedding of pathogens such as E. coli O157, but results are conflicting, probably because of the complexity of the interactions between all the factors involved.
