Toxic poultry feed contaminated by chromium-based leather tanning (as opposed to traditional slower vegetable tanning) is entering the food supply in Bangladesh through chicken meat, which is the most common source of protein in the country. Tanneries in Hazaribagh Thana, an industrial neighborhood of Dhaka, emit around 21,600 cubic meters of toxic waste each day. The tanneries also generate as much as 100 tonnes per day of scraps, trimmed raw hide, flesh and fat, which are processed into feed by neighborhood recycling plants and used in chicken and fish farms across the country.
