Random samples of beef meat (30 samples) were collected from different butcher shops in poor districts. After the preparation of press juice, samples were assayed (measurement of HADH activity in the press juice) using a spectrophotometric and colour test techniques.

The importance and danger of marketing the imported frozen meat without any control have been discussed.
