Animal Feed Question in the Shadow of Contemporary Food Crises [PDF ebook] 

This book shows that within the framework of EU, there has always been an ongoing struggle between two powers, food safety through feed hygiene and functioning of the market in financial terms. The direction of the outcome of this struggle depends on the balance of powers at a given time. For the question of "dilution principle" in the area of undesirable substances of feeds, this did work in favor of safety and the protection of the consumer. On the other hand, for the outstanding issues of "positive list" and "open declaration" in feed marketing, it is apparent that the outcome of the discussions so far supports the functioning of a "healthy" market rather, and the whole question is still pending.
