“…In the present study, the level of the carry-over of AFLB1 in compound feed into cows' milk in the form of AFLM1 was determined as 1.219±0.4139%. This result is in parallel with the values previously reported by other researchers (Patterson et al, 1980;Sarımehmetoğlu and Küplülü, 2004). …”

Aflatoxin in roughage, concentrates and compound feed from dairy farms located in Erzurum province, and the presence of Aflatoxin M1 (AFLM1) in the milk of animals fed with these feeds were determined in four different seasons. The mean level of Aflatoxin M1 detected in milk samples was 0.03 ppb. Aflatoxin M1 levels in the milk samples taken from the holdings were lower in autumn and summer (0.02 ppb) compared to winter and spring (0.04 ppb). The total aflatoxin levels in feed samples were higher in spring and summer, compared to autumn and winter. Furthermore, Aflatoxin B1 (AFLB1) levels in roughage, concentrate and compound feed were significantly higher in spring and summer, compared to autumn and winter (P<0.01). The results obtained in this study demonstrated that Aflatoxin B1 received with compound feed by cattle led to a carry-over of Aflatoxin M1 into milk at a level of 1.219±0.4139%. The mycotoxin levels detected were below the maximum residue limits laid down in the Turkish Food Codex.

“…When consumed by lactating cows, AFB 1 has adverse e¡ects on feed intake and milk production (Applebaum et al, 1982). When lactating animals are fed AFB 1 , they secrete the carcinogenic and mutagenic (Wong and Hsieh, 1976) metabolite AFM 1 into milk (Patterson et al, 1980). Thus dairy products, including cheese and ice-cream, may be contaminated (Goto et al, 1986;Munksgaard et al, 1987;Phillips et al, 1994).…”

Aflatoxin B1 Binding to Sorbents in Bovine Ruminal Fluid

et al. 2005

A recent approach to the problem of contamination of agricultural products by aflatoxin B(1) (AFB(1)) is to add non-nutritional adsorbents to animal diets in order to sequester ingested aflatoxins. We conducted in vitro experiments to develop a rapid and cheap model using ruminal fluid to assess the ability of sorbent materials to bind AFB(1). Seven sorbents (hydrated sodium calcium aluminosilicate; clinoptilolite; zeolite; two types of bentonite; sepiolite; and PHIL 75), commonly added to bovine diets were incubated in water and ruminal fluid in the presence of AFB(1). Hydrated sodium calcium aluminosilicate, sepiolite and one of the bentonites bound 100% of the AFB(1) in the presence of both ruminal fluid and water; clinoptilolite bound about 80% of AFB(1) in both liquids; whereas the affinities for the mycotoxin of zeolite (50%) and the other sample of bentonite (60%) in water seem to be increased by about 40% in ruminal fluid incubations. PHIL 75 had the poorest binding ability: about 30% in water and 45% in ruminal fluid. In view of the differences in toxin binding in water and ruminal fluid, it is preferable to use the ruminal fluid model for the in vitro pre-screening of sorbent materials potentially useful as adjuvants to ruminant feeds.

“…Dolayısıyla, sütte AFM 1 değerleri üzerine hayvanların bireysel metabolizmalarının farklı oluşu da etkili olabilir. Çünkü, alınan gıdalardaki AFB 1 'in sütte AFM 1 'e dönüşümünün % 0,8-2,2 oranında olduğu, ancak bu oranın hayvandan hayvana, laktasyon periyoduna ve süt miktarına bağlı olarak değiştiği bildirilmiştir (22).…”
