1994 Schwan's Ice Cream Contaminated by Raw Eggs

The Minnesota Department of Health noted a sharp increase in reports of Salmonella Enteritidis. A few weeks later, the FDA and state health officials determined that contaminated ice cream was the likely cause. The ice cream products were distributed nationwide. Investigators suspected that raw, unpasteurized eggs were hauled in one or more tanker trucks that later carried pasteurized ice cream premix to the Schwan's ice cream processing plant. Salmonella was isolated from ice cream, but not from the ice cream processing plant. A study of Schwan's customers showed an increased risk of gastrointestinal illness after consumption of Schwan's ice cream.
