The arrangements I introduced last year mean that each element of the meat and bone meal process — the rendering of offal into meal, the supply, distribution and feeding of it — is regulated separately. When we carry out a test and find tiny traces of meat and bone meal, as happened in the 76 samples, we look at the licensing stocks arrangement. While it is true that there is a technical control analysis difficulty in differentiating between two elements, we can determine whether the stocks are due to cross contamination or whether avian meat and bone meal is being fed.
