Despite these advantages, the reintroduction of PAP was complex and also sensitive. “You can sense that since the BSE crisis, not everyone has been positive about using PAP. It was assumed that BSE, or ‘mad cow disease’, could be passed on through animal meal from infected animals. Now with the reintroduction there now are very strict rules and regulations to follow: the animal must be classed as healthy at the abattoir. For example: from the same pig we eat a ham from, PAP is made for poultry feed. Adding PAP from poultry into poultry feed, or PAP from pigs into pig feed remains prohibited. That separation is very strict, down to the DNA level.”
PAPs from different animals are also strictly separated logistically and physically. This legislation does come with challenges. “Complete separation of production lines is not easily done at every production facility and sometimes requires an investment that exceeds the benefits. In the Netherlands, we choose to process pig PAP into poultry feed in Zelhem and Delden, and in Germany we also process PAP in Rapshagen and Langförden.”
