Abstract

Mikotoksini su toksični sekundarni metaboliti plijesni koji kontaminiraju usjeve diljem svijeta te čine velike štete u gospodarstvu. U svijetu je poznato oko 400 vrsta plijesni koje uzrokuju mikotoksikoze - različite bolesti u ljudi i životinja. Sinteza mikotoksina povezana je s određenim ekološkim uvjetima od kojih su temperatura, oborine i vlaga ključni čimbenici za produkciju toksina. Zbog klimatskih promjena, ovi čimbenici se drastično mijenjaju pa se posljedično narušavaju poznati obrasci sinteze mikotoksina čime se dovodi u pitanje sigurnost proizvodnje hrane u budućnosti. Mikotokiskogene plijesni imaju sposobnost prilagodbe na nove klimatske uvjete stoga bi u sljedećih 20 godina kontaminacija mikotoksikogenim plijesnima mogla zadati velike probleme u poljoprivredi i osiguranju zdravstvene ispravnosti hrane. Aflatoksini, postat će potencijalna opasnost u umjerenom klimatskom pojasu, dok bi u tropskim krajevima mogli potpuno nestati zbog previsokih temperatura. S druge strane, fuzarijski mikotoksini koji su karakteristični za umjereni pojas mogli bi se pojaviti u sjevernim predjelima svijeta gdje će činiti velike štete na žitaricama i kukuruzu.

Abstract (english)

Mycotoxins are toxic secondary metabolites of molds which are contaminating crops around the world thus causing immense damage to the global economy. There are approximately 400 kinds of molds known in the world causing mycotoxicosis – different diseases to humans and animals. Synthesis of mycotoxins is connected with certain ecological conditions out of which temperature, precipitation and moisture are key factors for toxins production. Due to climate changes, these factors change drastically; therefore known patterns of mycotoxins synthesis are disturbed, bringing safety of the food production into question. Mycotoxigenic molds have the ability to adapt to new climatic conditions, so in the next 20 years, contamination of mycotoxigenic molds could become a major problem in agriculture and food safety. Aflatoxins would become a potential danger in moderate temperature zone while in the tropics they could disappear completely due to too high temperatures. On the other hand, fusarium mycotoxins which are characteristic for the moderate temperature zone could occur in northern regions of the world where they will cause great damage to cereals and corn.
