Abstract: | Experimental short time production of aflatoxins in mixed feeds at 22, 28 and 37 °C as related to various moisture contents was studied. Growth of Aspergillus parasiticus was not observed in the meals with a moisture content ranging around 15% (22, 28 and 37 °C); the lowest quantifiable total aflatoxins at the fourth day was detected at 22 °C with 19.4% of moisture content; the higher total quantity of aflatoxins (113 mg/kg) was produced at 28 °C with 29.3% of moisture content. The ratio aflatoxin B1/aflatoxin G1 increased as the temperature raised. |
