1. Fusarium and Aspergillus mycotoxins contaminating wheat silage for dairy cattle feeding in Uruguay
Abstract Wheat is one of the most important cultivated cereals in Uruguay for human consumption; however, when harvest yields are low, wheat is usually used in ensiling for animal feeding. Ensiling is a forage preservation method that allows for storage during extended periods of time while maintaining nutritional values comparable to fresh pastures. Silage

2. RESÍDUOS DE BIFENILOS POLICLORADOS EM ARROZ E FEIJÃO DO ESTADO DO RIO GRANDE DO SUL / RESIDUES OF POLYCHLORINATED BIPHENYL IN RICE AND BEANS IN THE STATE OF RIO GRANDE DO SUL
Polychlorinated biphenyls (PCBs) were commercially produced between 1929 and the mid 1980s with industrial purposes. The same properties that interested industrially, as chemical inertness, high dielectric constant, resistance to burning; were also responsible for the spreading of the PCBs in all of the environmental compartments, mainly due to the inadequat

3. Efeitos da radiação gama no fungo Alternaria alternata e nas micotoxinas alternariol e alternariol monometil éter em amostras de cereais artificialmente contaminadas. / Effects of gamma irradiation on the fungus Alternaria alternata and on mycotoxins Alternariol (AOH) and Alternariol Monomethyl Ether (AME) in artificially contaminated cereal samples.
The present study aimed to evaluate the effects of different gamma irradiation doses on the growth of Alternaria alternata and on production of mycotoxins Alternariol (AOH) and Alternariol Monomethyl Ether (AME) in cereal samples. The results showed a significant reduction in the number of CFU/g in rice grains and sunflower seeds, which were proportional to

4. Monitoramento de aflatoxinas, fungos toxigênicos e níveis de contaminação em matérias primas e alimentos balanceados. Aflatoxicose natural em cães no estado do Rio de Janeiro / Aflatoxins survey, toxicogenic fungi and contamination level in raw material of balanced feedstuff. Natural aflatoxicoses in dogs of Rio de Janeiro State
The commercial feed constitutes an important element in the pet industry in Brazil. Its composition includes cereal mixtures produced in farms such as sorghum, maize and some oily seeds. All feed destined to pets are supplemented with fats, vitamins, minerals, antirust and flours of diverse origins incorporated in some cases as pellets. When conditions of nu

5. Fumonisinas em produtos e em variedades de milho argentinos
Com, or maize (Zea mays L.), is the world third leading cereal crop, after wheat and rice. The United States produces nearly 40% of the total world production. The next largest comproducing countries are the People s Republic of China and Brazil. Argentinean com accounts for 2 percent of the total world production. In Argentina com occupies a third of the cu

6. Immunochemical assessment of mycotoxins in 1989 grain foods: evidence for deoxynivalenol (vomitoxin) contamination.
To assess the potential for mycotoxin contamination of the human food supply following the 1988 U.S. drought, 92 grain food samples were purchased from retail outlets in the summer of 1989 and surveyed for aflatoxin B1, zearalenone, and deoxynivalenol (DON [vomitoxin]) by monoclonal antibody-based competitive enzyme-linked immunosorbent assay (ELISA). Only o

7. A Sensitive and Inexpensive Yeast Bioassay for the Mycotoxin Zearalenone and Other Compounds with Estrogenic Activity
Zearalenone (ZON) is a nonsteroidal estrogenic mycotoxin produced by plant-pathogenic species of Fusarium. As a consequence of infection with Fusarium culmorum and Fusarium graminearum, ZON can be found in cereals and derived food products. Since ZON is suspected to be a cause of human disease, including premature puberty syndrome, as well as hyperestrogenis
