The 25 foods most likely to cause foodborne illness

Chipotle is finally seeing more customers come through its doors following a major E.coli outbreak last year. Among dozens of apologies by Chipotle execs, wide coverage of the chain's new-and-improved safety checks and promises of free food, it seems things are on their way to returning back to normal.

This and the many major foodborne illness outbreaks reported of late highlight the importance of food safety. Knowing where your meals come from and the risks associated with different types of food is key to keeping potential bacteria at bay.

Of course, there are times when you cannot anticipate when a meal is safe. HealthGrove crunched the numbers to identify the top 25 foods that are most commonly involved in foodborne illness outbreaks. The health data visualization site, part of the Graphiq network, looked at data from the Centers for Disease Control and Protection, which documented all known foodborne illness outbreaks from 1998-2014.

It is important to note that the CDC aggregates foodborne illness reports from state and local reporting agencies, and it is up to these agencies to classify the food that caused a given outbreak. They then found the food types that caused the most outbreaks in that time span and ranked them by the most average annual outbreaks. Ties are broken by the average number of people affected per outbreak.

From the CDC: CDC is only directly involved in outbreak investigations that involve more than one state, or are particularly large, or when the state or local health department requests assistance. More information on how foodborne investigations are conducted can be found on CDC's Investigating Foodborne Outbreaks web page.
