According to the Centers for Disease Control, about one in six Americans gets food poisoning each year. Additionally, virus infection risks from consumption of raw oysters in the U.S. are estimated to cost around $200 million a year.

To address the issue of health risk from eating raw oysters, Texas A&M University graduate student Chandni Praveen, along with Texas A&M AgriLife Research scientist Dr. Suresh Pillai and a team of researchers from other agencies and institutions, studied how electron-beam pasteurization of raw oysters may reduce the possibility of food poisoning through virus.

Other entities involved in the study included the U.S. Department of Agriculture, the U.S. Food and Drug Administration and University of Texas School of Public Health-El Paso regional campus.

Pillai said that the study showed if a serving size of 12 raw oysters were contaminated with approximately 100 hepatitis A and human noroviruses, an e-beam dose of 5 kGy (kilograys) would achieve a 91 percent reduction of hepatitis A infection risks and a 26 percent reduction of norovirus infection risks. A kilogray is a unit of absorbed energy from ionizing radiation.
