Deli meats distributed to Walmart stores nationwide and sold in sandwiches have been recalled because of possible listeria contamination, CNN reports. This bacteria causes listeriosis, which can lead to miscarriages and sometimes fatal infections in those with weakened immune systems, such as infants, according to CNN.

The U.S. Department of Agriculture (USDA) announced the voluntary recall of Tyson Foods' Zemco Industries deli meats under the label brand Marketside. The targeted meats include ham and roast beef (for a complete list, visit the USDA website here); the packages are stamped with vendor number 398412808, and were made between June 18 and July 2 with "use by" dates between Aug. 20 and Sept. 10.

According to the Centers for Disease Control and Prevention, pregnant women are 20 times more likely to become infected with listeria than nonpregnant adults. It is most dangerous and common during the third trimester, when a mom-to-be's immune system is most suppressed.

The lowdown on deli meat from our experts: If you can, try to avoid eating it. Deli meats and hot dogs can transmit listeria, which causes listeriosis (symptoms include headache, muscle aches, fever, nausea, vomiting, stiff neck and convulsions).

If you MUST have hot dogs or deli meats, make sure they have been reheated to steaming (about 140° F to 160° F) to kill the bacteria. While eating out, moms-to-be should order non-deli meat sandwiches, such as meatballs, steak or roasted chicken.
