Concerns over food safety are growing this summer after a massive cyclospora outbreak linked to contaminated iceberg lettuce.

There have been recent reports of other food safety scares, including salmonella in eggs and jalapeños, E. coli in frozen blueberries and more.

Tuesday on Midday Edition, we discuss the outbreaks and what it reveals about our current food system.

Then, new research from UC San Diego and the University of Freiberg in Germany shows that one month on a vegan diet can alter how your body interprets DNA markers associated with aging and inflammation. We dive into the study.
