Description Aflatoxin contamination is a qualitative problem in groundnut (Arachis hypogaea L.) occurring
at both pre-and post-harvest stages. These aflatoxins are secondary metabolites produced by
Aspergillus flavus and A. parasiticus and have carcinogenic, hepatotoxic, teratogenic and
immuno-suppressive effects. To evaluate the prevalence of A. flavus infection and aflatoxin
contamination in groundnut oil mills/traders’ of 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 pod samples
were collected (Three samples from the each selected oil mill). Aflatoxin contamination in
kernels was estimated by indirect competitive ELISA. In Telangana, kernel infection ranged from
42 (Mahaboobnagar) to 90.7% (Nizamabad). In AP, Tadimarri mandal recorded kernel infection
up to 29.3% whereas Tadipatri recorded up to 59.3%. Aflatoxins in kernels from these mills in
Telangana were highest in Rangareddy (1205.2 µg kg-1
) followed by Karimnagar (365.5 µg kg-1
).
Oil mills of Nizamabad and Mahaboobnagar have recorded aflatoxins to a tune of 4.9 and 11.5
µg kg-1 in Telangana. In AP, aflatoxins in pod samples were 2.8 µg kg-1
(Tadipatri) and 6148.4 µg
kg-1 (Tadimarri).
