A jury has awarded $830,000 to the family of a man who died after developing salmonella poisoning from contaminated milk in 1985.

The award is one of the largest growing out of the incident that affected thousands of consumers who bought the milk in the Chicago area. The contamination was later traced to a defect in processing equipment at a dairy owned by Jewel Foods Co.The award in Cook County Circuit Court went to the estate of Anthony Affatato, who died 58 days after being infected.

The jury found Jewel, a unit of American Stores Co., was responsible and also held that two doctors and a hospital were negligent in their treatment of Affatato. American Stores is based in Salt Lake City.

Robert Holstein, a lawyer for the family, said the supermarket company, the hospital and the two doctors were assessed roughly equal portions of the $830,000 judgment.
