“…Studies on chickens (Davidson et al, 1987), pigs (Harvey et al, 1989a,b), goats (Nageswara Rao and Chopra, 2001) and cows (Harvey, 1991b) indicate that the inclusion of sorbents in the diet reduces food-borne exposure to a£atoxins, and that the percentage reduction of carry-over depends on the amount of a£atoxin used and the concentration and type of adsorbent fed. In fact, the sorbents used vary considerably in chemical structure and ability to sequester mycotoxin.…”

Aflatoxin B1 Binding to Sorbents in Bovine Ruminal Fluid

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.

“…The higher rate of passage in milk of AFM2 might be related to the lower amount of AFB2 present in contaminated feed. An inverse correlation was observed between AFB1 administered by feeding and AFM1 excreted in sheep and goats milk Ronchi et al 2005;Nageswara Rao and Chopra 2001).…”

For its nutritional composition, donkey milk is an excellent alternative to breast milk for infants suffering from cow's milk allergies. Even in donkeys, a passage of aflatoxin from contaminated feed to milk could occur, as reported by many authors in other dairy species, but there are no studies on this topic. This work was aimed at studying the excretion of aflatoxin M1 (AFM1) and M2 (AFM2) in milk after feeding trials with contaminated feed. Six donkeys, at the end of lactation, received a diet with naturally contaminated corn containing 202 and 11 μg.kg −1 of aflatoxin B1 (AFB1) and aflatoxin B2 (AFB2), respectively. Individual milk samples were analyzed for AFM1 and AFM2 for 15 days after the contaminated feed administration. Amounts of AFM1 and AFM2 were detected in the milk. The steady state condition was reached after 6 days. No AFM1 or AFM2 were detected in milk after 28 h from the last contaminated feed administration. The carryover from AFB1 to AFM1 and from AFB2 to AFM2 was found to be 0.02 and 0.31%, respectively. The results obtained in this study are thus a further step toward understanding the possible carryover of aflatoxin in donkey milk.

“…For this reason, the transfer of AFM1 into milk of cows (Veldman et al, 1992;Diaz et al, 2004;Masoero et al, 2007), goats (Smith et al, 1994;Rao and Chopra, 2001), and sheep (Battacone et al, 2003(Battacone et al, , 2005(Battacone et al, and 2009) fed contaminated diets during a medium-long period has been extensively investigated. Overall, several studies (Frobish et al, 1986;Battacone et al, 2009) showed that AFM1 excretion in milk was doserelated and reached a steady-state concentration after 2, 4 or more days of continuous ingestion of AFB1.…”

“…The main types of SAs currently employed on farm conditions belong to three main groups, namely clay minerals (e.g., bentonite, hydrated sodium calcium aluminosilicate (HSCAS), zeolites, smectite, and montmorillonite; Phillips et al, 1991;Ramos and Hernandez, 1996;Rao and Chopra, 2001;Diaz et al, 2003;Jouany, 2007), yeast cell wall based products (Karaman et al, 2005;Yiannikouris et al, 2005) and activated carbons (Galvano et al, 1996;Rao and Chopra, 2001;Diaz et al, 2003;Diaz and Smith, 2005).…”

Chemical hazards may occur in any phases of the different livestock production systems. Aim of this review is to address an update about the key issues related to the risk of contamination in foods of animal origin by environmental contaminants linked to industrialisation or urbanisation (e.g., heavy metals and persistent organic pollutants), and natural contaminants (e.g., mycotoxins). This review deals with current issues and future perspectives on the complex issue of the safety of feeds and foods of animal origin, by taking into account the estimation of the occurrence of chemical residues in food, the hazard identification and characterisation of mycotoxins in animal feeds, and the analysis of feedstuffs as a tool to control and evaluate food safety.
