Guaranteeing a good egg?

The Agricultural Research Service has developed an oil emulsion vaccine to reduce the possibility of salmonella in chicken eggs.

Hens infected with Salmonella can transmit the organism into their eggs. People who eat infected eggs get salmonellosis, a disease characterized by nausea, vomiting and severe diarrhea.

In research tests, the vaccine was given to hens twice. The birds were then exposed to Salmonella enteritidis. The new vaccine reduced by 10-to-40%, the amount of S. enteritidis found in the feces of hens.
