Occurrence of ochratoxin A in black pepper, coriander, ginger and turmeric in India.

OA contamianation of black pepper, coriander seeds, powdered ginger and turmeric powder was estimated using indirect competitive ELISA. Samples were extracted with 0.5% KCI in 70% methanol and diluted in phosphate – buffered saline containing 0.05% Tween 20 and 0.2% bovine serum albumin. ELISA results were compared with those made by HPLC. All estimates were within 1 – 2 standard deviations of the ELISA values. More than 90% of OA added to spice samples was recovered from samples containing between 5 and 100 mg/kg. In 126 samples obtained from retail shops, OA was found to exceed 10 mg/kg in 14/26 black pepper samples, 20/50 coriander samples, 2/25 ginger samples and 9/25 turmeric samples. This is the first record in India of the occurrence of OA in what are some of the most widely used spices in Indian cooking.
