A Salmonella heidelberg epidemic in a hospital nursery was traced to
infected calves on a dairy farm where the mother of the index patient
lived. The Salmonella isolates from all cases were resistant to
chloramphenicol, sulfamethoxazole, and tetracycline. Verification of the
spread of infection from the farm animals to a hospital population is
unusual and raises questions about the hazards of antibiotic animal-feed
preparations that may induce infection with resistant organisms in humans.
