Salmonella spp. in non-edible animal products: a burden on the broiler industry

Abstract

The slaughter process produces carcasses, which are of greater commercial value, and by-products, which can be separated into edible or non-edible products. The latter is intended for the preparation of products not fit for human consumption, such as animal meal. The use of animal meal as feed ingredients reduces the environmental damage caused by the waste from the slaughterhouses and supplies nutritional and economic characteristics in the poultry sector. However, contamination by microorganisms such as Salmonella spp. plays an important role in the spread of the pathogen in poultry farms. This in turn negatively impacts poultry performance and can be a consumer health risk. In this report, we review the process for extracting proteinaceous waste from these by-products and the risk of contamination by Salmonella spp. in the food chain of animal products.
