After the cantaloupe-associated listeriosis outbreak linked to a Colorado farm that has left 15 people dead and 84 sick across 19 states, it is romaine lettuce now threatening to spread the infection in North America.
A random sample of romaine lettuce from True Leaf Farms of California taken by the U.S. Food and Drug Administration has tested positive for the bacteria.
The produce seller has already recalled about 30,000 pounds of chopped and bagged romaine lettuce in 90 cartons.
"We are fully cooperating with the FDA, and we are contacting all of our customers to ensure prompt removal of any product potentially associated with the recall," said Steve Church, owner of True Leaf Farms. "We are committed to conducting this recall quickly and efficiently to reduce any risk to public health."
