Occurrences and frequency of fungi and detection of mycotoxins on poultry rations in Yemen

Abstract

The results indicated that the samples collected from Taiz companies showed that high concentrations of aflatoxins ranged 26–45 ppb, than other samples which were collected from Sana’a while the fumonisins were 1–5.9 ppm. Moreover, lower concentrations of fumonisins were collected from Taiz companies (0.65–0.93 ppm). Aflatoxins in samples collected from farmer’s poultry in Taiz and Dhamar were 42.5 ppb. Also in samples from Sana’a and Ibb, the high concentration found is 39 ppb. The maximum significant mean of aflatoxins production was 25.2 ppb at 25 °C. Aflatoxins production was decreased at lower or higher tested temperature (3.6, 9.93 ppb) at 15 °C and 35 °C respectively. Similarly, fumonisin produced at 25 °C was 1.65 ppm, but decreased at lower or higher temperatures tested 1.3 and 0.54 ppm at (15 °C and 35 °C respectively.
