Aflatoxins in feed

Abstract

Background. Mycotoxins are toxic secondary metabolites, which are synthesized from a large number of intermediates from the primary metabolism of saprophytic molds. Aflatoxins, due to their genotoxic and carcinogenic effects, are the most important group of mycotoxins from the aspect of their impact on human and animal health. Of all known aflatoxins, AFB1 is the most frequent, with the most harmful impact on human and animal health. Scope and Approach. Due to their prevalence and toxicity, monitoring the presence of aflatoxins in the food chain is required. The scope of this paper is to provide information on the presence of aflatoxins in animal feed and in milk. This paper describes temperature increases in Europe that are contributing to the increased presence of aflatoxins in food, as well as aflatoxin prevention and protection measures. Key Findings and Conclusions. During the last decade, serious contamination of corn with aflatoxins was recorded in southern Europe. In the summer of 2012, Serbia recorded high concentrations of aflatoxins in corn and milk. Based on climate change data, it is expected that aflatoxin contamination in corn will become more frequent.

Uvod. Mikotoksini su toksični produkti sekundarnog metabolizma saprofitskih plesni, koji se sintetišu od velikog broja međuprodukata primarnog metabolizma. Aflatoksini zbog genotoksičnog i kancerogenog dejstva predstavljaju najznačajniju grupu mikotoksina sa aspekta uticaja na zdravlje ljudi i životinja. Od svih poznatih aflatoksina, AFB1 je najfrekventniji sa najštetnijim uticajem na zdravlje ljudi i životinja. Cilj i pristup. Zbog svoje zastupljenosti i toksičnosti aflatoksini zahtevaju praćenje njihovog prisustva u lancu hrane. Cilj ovog rada je da pruži informaciju o prisustvu aflatoksina u hrani za životinje i u mleku. U radu su opisane globalne temperaturne promene koje povećavaju prisustvo aflatoksina u hrani, kao i mere prevencije i zaštite Ključni nalazi i zaključak. Tokom poslednje decenije, zabeleženo je ozbiljno zagađenje kukuruza sa aflatoksinima u južnoj Evropi. Republika Srbija je u leto 2012. godine zabeležila visoke koncentracije aflatoksina u kukuruzu i u mleku. Na osnovu podataka o klimatskim promenama, očekuje se da kontaminacije aflatoksinima u kukuruzu postanu učestalije.
