A recent episode of aflatoxin M₁ (AFM₁) found in cow milk produced in Acores, convoked to the problem of mycotoxins control in feed for dairy cows. Exposure control of milk-producing animals to mycotoxins, requires a systematic monitoring of feeds and raw materials. The European Union established maximum values for aflatoxin B₁ (AFB₁) in dairy cattle, ewe and goats feeds (5 µg/kg) (European Commission, 2011) and recommend guidance levels of zearalenone (ZEA; 500 µg/kg) in complementary and complete feeding stuffs for dairy cattle, sheep and goats (European Commission, 2006a). Portuguese dairy production is largely (70%) dependent on imported cereals and other grains for feed production, coming from the international market. All feed plants or home-mixers are officially approved, according to Regulation (EC) No 183/2005 (European Commission, 2005), enforcing the HACCP system application in each feed plant. However, the production conditions of feedstuffs, especially those imported from developing countries, are difficult to control, concerning the specific risk of mycotoxins contaminations. These kinds of hazards are mostly introduced in feed materials in the pre-harvest period and must be locally controlled through agricultural ‘good practices’. In this chapter, authors review published data from occurrence of AFB₁ and ZEA applied, particularly, to feed manufactured in Portugal and intended for dairy cattle, goat and ewe feeding. Attention is also given to raw materials used in dairy feed. Finally, the global impacts for the food chain of the presence of these toxins in dairy feeds are discussed, with relevance to the presence of AFM₁ in dairy foods.
