Norovirus most common foodborne pathogen in 2017

This is the CIDRAP summary of the latest CDC number crunching on microorganisms that lead to barfing.

The Centers for Disease Control and Prevention (CDC) late last week released a summary of foodborne illnesses in 2017 based on an annual analysis of data from the Foodborne Disease Outbreak Surveillance System, and norovirus was the most common pathogen reported, responsible for 46% of illnesses. Salmonella and Shiga toxin–producing Escherichia coli were also linked to a substantial number of outbreaks.  

In 2017, the CDC tracked 841 foodborne outbreaks, which included 14,481 illnesses, 827 hospitalizations, 20 deaths, and 14 food product recalls. A single etiologic agent was confirmed in 395 outbreaks (47%), which are defined as two or more related cases.

Tainted seafood and poultry were tied with causing the most outbreaks, with mollusks (41 outbreaks), fish (37), and chicken (23) the specific food items most often implicated. The most outbreak-associated illnesses were from turkey (609 illnesses), fruits (521), and chicken (487), the CDC said.

California had the most outbreaks (107), followed by Ohio (69), and Washington state (67). 

As in past years, restaurants with sit-down dining were the most commonly reported locations for food preparation associated with outbreaks (366).
