A foodbome disease characterized by nausea, abdominal pain and vomiting in University Hostel students was investigated. Epidemiological and laboratory investigations indicated that the disease was associated with the consumption of rice and soup contaminated with lead and copper. Lead was detected in rice (119.65 ppm), soup (42.6 ppm), vegetable curry (42.9) and vomitus (120.6 ppm) while copper was detected in soup (47.0 ppm) and vomitus (40.2 ppm). Metal entry into the food was due to improper tin coating of the copper vessels used for cooking.
