Abstract
Aflatoxin B1 (AFB1) is most frequently found in plant substrates, which has shown the highest toxigenic potential. Based on previous studies, the IARC has classified AFB1 as a class 1A human carcinogen. Several impacts on consumers, such as loss of human and animal lives; health care and veterinary care costs; contaminated foods and feeds disposal costs; and investment in research and management of the myco-toxin problem. Fourteen maize seed samples comprising of recommended and local varieties were collected from three maize growing zones (Zone I- Almora, Kullu, Bilaspur, Dhaulakuan, Kangara, Saharanpur, Zone II- Karnal, Ludhiana, Pantnagar, New Delhi and Zone III- Begusarai, Varanasi, Sabour-1 and Sabour 2). In our studies AFB1 toxin range were noticed Zone-I (0.0294- 153.5081 ppb), Zone-II (0.1761- 161.0537 ppb ppb) and Zone-III (3.8366- 53.1256 ppb) collected seed samples.This indicate that ELISA technique could be applied to the monitoring of Aflatoxin contamination in a lot of samples in a cost, accuracy, simplicity and time effective manner.
