Description In groundnut Aspergillus flavus causes aflatoxin contamination which is a qualitative problem
occurring at both pre-and post-harvest stages. These aflatoxins have carcinogenic, hepatotoxic,
teratogenic and immuno-suppressive effects. The A. flavus strains which produces aflatoxins are
called as toxigenic and which do not produce toxins are called as atoxigenic starins. To detect
the toxigenic and atoxigenic starins of A. flavus from Telangana and Andhra Pradesh (AP), pod
samples were collected from eight selected oil mills/traders’ in Mahaboobnagar, Rangareddy,
Nizamabad, Karimnagar (Telangana); and Anantapur (AP) districts. A total of 24 A. flavus
cultures were isolated from the collected pod samples. These isolates were identified as
toxigenic/atoxigenic using cultural detection methods on Yeast extract sucrose (YES) media and
coconut agar medium (CAM). Based on cultural methods, it was confirmed that there were18
toxigenic, five atoxigenic and one false positive/negative strain out of the 24 A. flavus isolates
obtained from surveyed oil mills. Atoxigenic strains were obtained from Karimnagar and
Nizamabad districts of Telangana.
