Safe valorization of slaughter by-products

As a result of the production of meat for human consumption, an annual flow of about 17 million tonnes of processed animal proteins (PAPs) is generated in the EU. To minimize the risk of "mad cow disease" (BSE), proteins from ruminants may not enter the animal feed production chain. In addition, there is a ban on intra-species recycling. Here the intention is that PAPs of pigs may not be fed to pigs of those of poultry should not be fed to poultry. The Dutch government, the European Union, and the Dutch business community want to reuse animal by-products in a safe way, but yet as wide as possible. The motivation is to better meet the requirements of social governance and to reduce the pressure on world trade in soya as feedstock.

This project aims to facilitate the application of pork PAPs in poultry feed. It is then required to demonstrate that the pig by-products are free of poultry proteins. There is an urgent need for detection methods to monitor poultry material in pork PAPs and in poultry feeds. This project focuses on the development of an ELISA (immunoassay) screening method and a qPCR confirmation method for detection of poultry proteins. In addition to the development and testing of the methods, the implementation of the methods at the companies will be facilitated.
