After feeding rests of slaughtered poultry together with whey, tapioca and residues of stark production to pigs 70% of the slaughtered pigs were refused by the meat inspection because of yellow fat and yellow hair. The occurrence of bile pigment, carotenoids and synthetic colours could be excluded while acid fast pigments were demonstrated in the fat tissue, liver and skeleton muscle. This could be confirmed by the peroxide number, acid number and the content of malondialdehyde and vitamin E. The results were discussed in the view of meat inspection laws.
