Purdue lab tests eggs for salmonella

The Indiana Animal Disease Diagnostic Laboratory at Purdue University is preparing to test eggs for salmonella, as required under a new federal law, according to the university. The rule requires farms with 50,000 or more laying hens that do not sell all eggs directly to consumers to comply with the rule by July 9.
The government set up the rule after detecting salmonella contamination in samples from egg farms across the U.S. If the bacterium is found, a producer will need to take additional steps including testing 4,000 eggs from that flock or treating the eggs with pasteurization, for example, for the flock's lifetime.
