Of the 39 outbreaks caused by foreign food (which caused 2,348 illnesses) from 2005 to 2010, 17 of them happened in 2009 and 2010, according to the report. Bad fish caused 17 outbreaks; spices were responsible for six.
Though nearly 45% of the cases came from food that had originated in Asia, the report found that nearly half of the outbreaks came from areas that hadn’t previously been associated with such diseases.
The true extent of the outbreaks is probably much more expansive than reported, according to the CDC.
“As our food supply becomes more global, people are eating foods from all over the world, potentially exposing them to germs from all corners of the world, too,” said epidemiologist and lead author Hannah Gould in a statement. “We saw an increased number of outbreaks due to imported foods during recent years, and more types of foods from more countries causing outbreaks.”
Food imports into the U.S. nearly doubled to $78 billion in 2007 from $41 billion in 1998, according to the Department of Agriculture. As much as 85% of seafood consumed in the country comes from abroad.
