(CNN) - Dale and Thomas Popcorn is voluntarily recalling bags of its flavored, ready-to-eat Indiana-brand products.
The FDA says there is concern about a possible Listeria contamination.
The recalled popcorn bags were distributed after August 8th and have "best by" dates of February 4, 2013 to March 12, 2013.
Listeria is most dangerous to young children, the elderly, people with weakened immune systems and pregnant women. It can cause a high fever, severe headaches, nausea, abdominal pain and diarrhea.
