A recall that was issued for ready-to-eat meat and poultry products sold in retailers nationwide and online has claimed at least one life, to the U.S. Centers for Disease Control and Prevention said Friday.

Yu Shang Food, Inc initially recalled more than 4,500 pounds of ready-to-eat meat and poultry products due to the produce being linked to a potential listeria contamination. According to a recall posted by the U.S. Department of Agriculture's Food Safety and Inspection Service (FSIS), the problem was originally discovered on Oct. 21.

The discovery was made during routine testing and follow-up activities of Yu Shang Food Inc. of Spartanburg, South Carolina. After additional testing, Yu Shang Food increased the total weight of recalled products from 4,589 to 72,240 pounds, according to the FSIS.

On Friday, the CDC said that 11 people have been infected with listeria across four states. From these cases, nine have been hospitalized and one person has died.

Here is what we know.

Listeriosis or listeria poisoning symptoms

Listeriosis, or listeria poisoning, is a foodborne bacterial infection most commonly caused by the bacterium Listeria monocytogenes. It is considered a serious condition and can be dangerous or life-threatening, especially to older adults, people with weak immune systems and pregnant people.

According to the USDA, symptoms include:

• Fever
• Muscle aches
• Headache
• Stiff neck
• Confusion
• Loss of balance
• Convulsions
• Diarrhea
• Other gastrointestinal symptoms
• Miscarriage, stillbirth, premature delivery and/or life-threatening infection of newborn infants

People in higher-risk categories who experience flu-like symptoms within two months after eating contaminated food should seek medical care and tell the health care provider about eating the contaminated food, said the USDA.
