Food irradiation: Is it safe?

Some of the food we eat -- especially spices and imported produce -- is irradiated for our safety. Food scientist Anuradha Prakash, Ph.D., professor and program director of the food science department at Chapman University, explains the process, effects and her research on food irradiation.

Prakash is joined by Larry Santora, M.D., medical director of the Orange County Heart Institute and host of "Health Matters with Dr. Larry Santora" television series, which airs weekly on PBS OC. Visit www.drsantora.com.

Produced by Chapman University's Panther Productions, "Health Matters with Dr. Larry Santora" is sponsored by St. Joseph Health, St. Joseph Hospital, Biotronik, Churm Media, The Widdicombe Family, Medtronic, Weaver Health Solutions and Abbott Vascular.
