Thesafety characteristics of feed used in fish and crustacean aquaculture systems are an essential tool to assure the productivity of those animal exploitations. Safety of feed may be affected by different hazards, including biological and chemical groups. The aim of this preliminary study was to evaluate fungi contamination and the presence of aflatoxins in 87 samples of feed for sea bass, collected in Portugal. Molds were found in 35 samples (40.2%) in levels ranging from 1 to 3.3 log10 CFU∙g−1. Six genera of molds were found. Aspergillus flavus was the most frequent, found in all positive samples, with a range from 2 to 3.2 log10 CFU∙g−1. Aspergillus niger was found in 34 samples (39.1%), ranging from 1 to 2.7 log10 CFU∙g−1. Aspergillus glaucus was found in 26 samples (29.9%) with levels between 1 and 2.4 log10 CFU∙g−1. Penicillium spp. and Cladosporium spp. were both found in 25 samples (28.7%). Fusarium spp. was found in 22 samples (25.3%), ranging from 1 to 2.3 log10 CFU∙g−1. All feed samples were screened for aflatoxins using a HPLC technique, with a detection limit of 1.0 μg∙kg−1. All samples were aflatoxin negative.

“…In Serbia, zearalenone, ochratoxin A and aflatoxin B 1 were detected in corn, wheat and barley destined for fish feed production. The authors recorded particularly high levels of zearalenone in corn (mean of 5.3 mg/kg) [41]. In Brazil, aflatoxin B 1 was detected, although in low doses (1.1 µg/kg to 7.4 µg/kg), in samples of soybean bran, corn bran and other cereals from fish farms [42].…”

Plant-based ingredients have been successfully replacing fishmeal in finished fish feeds. However, using crops in feeds results in an increased risk of contamination by fungi and mycotoxins and a higher incidence of mycotoxicosis in fish. This might decrease aquaculture’s productivity as mycotoxicosis generally result in decreased body weight, growth impairment and higher rates of disease and mortality in fish. Additionally, some mycotoxins might accumulate in the fish musculature. As such, fish consumption might become another way for mycotoxins to enter the human food chain, threatening food security and public health as mycotoxins are important genotoxins, carcinogens and immunosuppressors to humans. In this work we aim to provide a review on the most important mycotoxins found in crops and in finished fish feed, i.e., aflatoxins, fumonisins, ochratoxins, trichothecenes and zearalenone. We present their effects on the health of fish and humans and their regulations in the European Union. Although work has been performed in mycotoxin research ever since the 1960s, a lot of information is still lacking regarding its effects. However, it is noticed that in order to use crops in aquafeed production, efforts should be made in order to monitor its contamination by mycotoxinogenic fungi and mycotoxins.

“…As rações para animais são produzidas com vários ingredientes, como grãos, leguminosas, proteína animal, vitaminas e minerais, com quantidades adequadas para o crescimento rápido, saudável e ganho de peso (GRECO et al, 2017). Segundo Jakić-Dimić et al (2005), os cereais são fonte de energia e as leguminosas ricas em proteínas, e esses fazem parte da alimentação dos animas (90%), incluindo os peixes. PLATTNER; SOUZA, 2010), em psiciculturas é padrão oferecer rações extrusadas pela flutuabilidade e rendimento.…”

“…As condições para a produção de micotoxinas são geralmente mais restritas que aquelas necessárias para o crescimento fúngico e podem diferir entre diferentes micotoxinas produzidas pela mesma espécie de fungo (FRISVAD;SAMSON, 1991). No entanto, segundo Jakić-Dimić et al (2005), a produção de AFB 1 pode ocorrer em condições de, baixa atividade de água e temperatura, pois avaliando amostras de milho constatou crescimento fúngico em 100% das amostras, além de contaminação com zearalenona, ocratoxina A e aflatoxina B 1 .…”

Ocorrência de aflatoxinas em rações e tilápias (<i>Oreochromis niloticus</i>) no Brasil

Os peixes são uma importante fonte de proteínas, micronutrientes e ácidos graxos poliinsaturados. As tilápias (Oreochromis niloticus) têm um grande potencial de cultivo e ampla aceitação comercial. A deposição de aflatoxinas nos peixes é residual e cumulativa, no entanto há diferenças de sensibilidade entre as espécies e a legislação brasileira contempla limites apenas para rações de modo geral. O objetivo do trabalho foi avaliar a ocorrência de aflatoxinas em rações e tilápias de pisciculturas do Brasil. Foram coletadas 43 amostras de rações (500 g cada amostra) e 42 amostras de tilápias (500 g de peixe para compor uma amostra) de diferentes propriedades no Brasil. Amostras de ração, fígado e músculo foram avaliadas para aflatoxinas B 1 , B 2 , G 1 e G 2. As amostras foram analisadas por cromatografia líquida de alta eficiência (CLAE) utilizando colunas de imunoafinidade para a etapa de purificação. Foram encontrados 16,28% e 86,05% de amostras de ração positivas para AFG 1 e AFB 1 , respectivamente. No entanto, todas as amostras de ração mostraram-se dentro dos limites estabelecidos pela legislação brasileira. AFG 1 e AFB 1 foram detectadas em 7,14% e 85,72% das amostras de fígado, respectivamente, com níveis de 0,152 µg AFG 1 /kg e variando de 0,150 a 0,866 µg AFB 1 /kg. A AFB 1 foi encontrada em 19,05% das amostras de músculo, com níveis variando de 0,150 a 0,372 µg/kg. Embora os valores encontrados nas rações estejam abaixo dos limites estabelecidos e os níveis em fígado e músculo tenham sido baixos, o monitoramento e os esforços para a diminuição da exposição às aflatoxinas devem ser considerados.
