An infant is dead and nine people have been hospitalized amid a listeria outbreak in ready-to-eat meat and poultry products that has affected four states, including New York and New Jersey. The baby was from California, where seven other people have been hospitalized for infections connected to Yu Shang Food’s ready-to-eat meat and poultry products, according to the Centers for Disease Control. The CDC said one of those infected in the Golden State was pregnant with twins, both of whom died. But despite the two deaths, listeria was only found in one of the twins, as well as their mom. In Illinois, two people were infected by the outbreak, while New York and New Jersey reported one case each. A total of 11 people across those states are confirmed to have been infected, though it appears two of them did not need to seek treatment. All of the individuals have been of Asian heritage, ranging in age from less than 1 year old to 86 years old. The CDC predicts more people have gotten sick than the number reported, and says the outbreak could have reached other states. The outbreak was discovered in late October after routine tests detected listeria in the products and facility of Yu Shang Food, headquartered in Spartanburg, S.C. The affected products had been shipped to retail locations nationwide and were available online. The company has since recalled more than 72,000 pounds of ready-to-eat meat and poultry products. The recall was first issued on Nov. 9 but was expanded on Thursday. It affects foods produced before Oct. 28. A full list of recalled products can be found on the USDA’s website.
