A Maryland resident who traveled to El Salvador has been diagnosed with New World screwworm. It's the first reported U.S. case tied to travel to a country with a current outbreak. The Centers for Disease Control and Prevention confirmed the diagnosis three weeks ago. Federal health officials acknowledged the infection in an emailed statement Monday. Health officials say the parasite does not spread from person to person and that the risk to the public is very low.

Anyone firing up the grill this summer already knows hamburgers and steaks are expensive, but the latest numbers show prices have climbed to record highs. And experts say consumers shouldn't expect much relief soon either. According to U.S. government data, the average price of a pound of ground beef rose to $6.12 in June, up nearly 12% from a year ago. The average price of all uncooked beef steaks rose 8% to $11.49 per pound. But this is not a recent phenomenon. Beef prices have been steadily rising over the past 20 years because the supply of cattle remains tight while beef remains popular. That's not likely to change.
