Aflatoxins, a group of mycotoxins mainly produced by Aspergillus flavus and A. parasiticus, have adverse health effects on humans and livestock that ingest aflatoxin- contaminated food products and feeds. To secure the safety of food and feed, regular monitoring of aflatoxin levels is necessary. In order to understand the magnitude of aflatoxin contamination, a survey was conducted in different agro-ecological zones of Tamil Nadu, India and 242 samples consisting of pre- and post-harvest maize kernels, food products, poultry and livestock feeds were collected from farmers' fields, poultry farms, retail shops and supermarkets and analyzed for aflatoxin B1 (AFB1) contamination by enzyme- linked immunosorbent assay (ELISA) using antiserum raised against aflatoxin B1-Bovine serum albumin (AFB1-BSA). The results indicated that 61.3% of the maize kernel samples were contaminated with AFB1 and the levels of AFB1 in 26% of the pre- and post-harvest maize kernels exceeded 20 μg/kg. The highest level of AFB1 (245 μg/kg) was recorded in post-harvest maize kernel samples. In food products AFB1 was detected only in two samples out of 30 samples tested. Furthermore, the levels ranged from 0.6 to 3.7 μg/kg. In poultry feeds, AFB1 was detected in 30 out of 53 samples and the levels ranged from 0.7 to 31.6 μg/kg. Among the 40 livestock feed samples evaluated 29 samples were contaminated with AFB1 at level ranging from 1.8 to 244.9 μg/kg.

Aflatoksyny, grupa mykotoksyn wytwarzanych głównie przez Aspergillus flavus, ma szkodliwy wpływ na zdrowie ludzi i zwierząt domowych spożywających produkty spożywcze i paszę skażone aflatoksyną. Aby zapewnić bezpieczeństwo żywności i paszy, potrzebny jest regularny monitoring zawartości w nich aflatoksyny. W celu rozpoznania zakresu skażenia aflatoksyną przeprowadzono badania w różnych agroekologicznych strefach Tamil Nadu w Indiach. Pobrano 242 próby ziarniaków kukurydzy przed i po zbiorze, produkty spożywcze, drób i paszę zwierzęcą uzyskano z pól farmerskich, farm drobiu, sklepów detalicznych i supermarketów, a następnie analizowano je na obecność zakażenia aflatoksyną B1 (AFB1) przy wykorzystaniu serum albuminy (AFB1--BSA). Wyniki badań wskazywały, że 61,3% prób ziarniaków kukurydzy było skażone AFB1, a poziom AFB1 w 26% ziarniakach pobranych przed i po zbiorze kukurydzy przekraczał 20 μm/kg. Najwyższy poziom AFB1 (945 μm/kg) wykryto w próbach ziarniaków pobranych po zbiorze. W produktach spożywczych AFB1 wykryto tylko w dwóch próbach z 30 prób badanych. Ponad to, poziom ten zamykał się w granicach od 0,6 do 3,7 μm/kg. W paszy dla drobiu, AFB1 wykryto w 30 próbach z 53 badanych, a poziom AFB1 wynosił od 0,7 do 31,6 μm/kg. Spośród 40 prób badanej paszy zwierzęcej 29 prób było skażonych AFB1 na poziomie od 1,8 do 244,9 μm/kg.
