CDC: STEC infections have declined since 2006, Salmonella infections have risen

Rates of infection from Shiga toxin-producing E. coli (STEC) have fallen slightly in the past five years, according to data released by the Centers for Disease Control and Prevention Friday.

In 2006, there were 590 laboratory-confirmed cases of infection caused by STEC. In 2011, the most recent available data, there were 463 infections, according to the report.

Oppositely, Salmonella infections have risen throughout the past half a decade, but are down from last year. In 2006, there were 6,689 infections with 7,763 in 2011. Still, last year’s number is below the 2010 figure of 8,273.

Rates of infection from Campylobacter and Listeria also have risen slightly.

The numbers come from FoodNet, a surveillance network established in 1996 to track nine foodborne pathogens: Campylobacter, Crytosporidium, Cyclospora, Listeria, Salmonella, Shiga toxin-producing E. coli (O157 and non-O157), Shigella, Vibrio and Yersinia.

In 2011, FoodNet found almost 19,000 foodborne illness infections, with Salmonella being the most common, followed by Campylobacter, Shigella, Cryptosporidium and STECs.

Of those almost 19,000 infections, there were 67 deaths attributed to eight of the nine monitored illnesses, according to the report.
