Re-evaluation of aflatoxin M1 transfer into milk of high-yielding cows considering ration composition

Carry-Over of Aflatoxin B1 to Aflatoxin M1 in High Yielding Israeli Cows in Mid- and Late-Lactation

The potent hepatotoxin and carcinogen aflatoxin B1 (AFB1) is a common mycotoxin contaminant of grains used in animal feeds. Aflatoxin M1 (AFM1) is the major metabolite of AFB1 in mammals, being partially excreted into milk, and is a possible human carcinogen. The maximum permitted concentration of AFM1 in cows' milk is 0.05 μg/kg in Israel and the European Union. Since milk yield and the carry-...

Aflatoxin M1 in Milk - FSA4018

Aflatoxins are mycotoxins of major concern to the dairy industry. Most mycotoxins are found in grain, usually grown in a drought, although they may contaminate pasture grass and occasionally hay. Most frequently, aflatoxins are found in corn (see Figures 1-3) and cottonseed, and sometimes in their byproducts, but also on rare occasions in soybeans or distiller’s grain. Peanut products also may ...

Identification of Aflatoxin Contamination in the Milk of Cows Fed on Moldy Dry Bread as a Part of Their Ration

Introduction: Contamination of foodstuffs with fungi and the toxins produced by them is a very important problem in human and animal feeding. In most villages around Shiraz, in small-scale dairy farms, dry leftover bread which is mostly contaminated with fungi is used as a part of food ration for animals. The thin-layer chromatographic method which was used for determination of aflatoxin. Inges...

Effects of Milk Yield, Feed Composition, and Feed Contamination with Aflatoxin B1 on the Aflatoxin M1 Concentration in Dairy Cows’ Milk Investigated Using Monte Carlo Simulation Modelling

This study investigated the presence of aflatoxin M1 (AfM1) in dairy cows' milk, given predefined scenarios for milk production, compound feed (CF) contamination with aflatoxin B1 (AfB1), and inclusion rates of ingredients, using Monte Carlo simulation modelling. The model simulated a typical dairy farm in the Netherlands. Six different scenarios were considered, based on two lactation and thre...
