No. There have been no reports illnesses connected to consuming the foods from any of the most recent recalls.

Fresh Express recalled its Chicken Caesar salad kits sold in California, Texas, Louisiana and Washington sate with use buy dates of Oct. 26, 27 and 30 and Nov. 2. The company said the kits include chicken from BrucePac that was included in that company's recall for potential listeria contamination in early October.

The smoked salmon recall, issued because of potential contamination with the listeria bacteria, applies only to packages with the lot number 8512801270.

The recall applies to Chicken Street Taco Meal Kits with best buy dates between Sept. 2 and Nov. 7 with the UPC 205916813991.

TreeHouse Foods on Oct. 18 issued a voluntary recall of dozens of frozen waffle products sold under various brand names like Kodiak, Simple Truth (Kroger’s brand), Good and Gather (Target), and Great Value (Walmart), as well as those sold under the Stop and Shop, Food Lion, Giant Eagle, Harris Teeter, Hannaford and other store brands. On Oct. 22, the recall was expanded to include Belgian waffles and various pancake items. A list of impacted brands and their correlating UPCs, lot codes and "Best By" dates has been issued by the company.

BrucePac packaging issued a recall of ready-to-eat meat and poultry items produced at its plant in Durant, Oklahoma facility from May 31 to Oct. 8. The recall applied to nearly 10 million pounds of product that were shipped nationwide and distributed to restaurants, schools and grocers—including Costco, Trader Joe's, Target, Walmart and Kroger—and was sparked by the discovery of products positive for listeria during routine testing at the facility later found to have come from contaminated chicken. On Oct. 15, the U.S. Department of Agriculture added another 1.7 million pounds of product to the recall. The USDA is maintaining a 300-plus-page searchable list of recalled products, which includes popular items like southwestern style mini burritos sold at Costco; Trader Joe's branded lemon chicken and arugula salad, white meat chicken salad and chicken chow mein; and a dozen Kroger brand pre-made salad kits.

No. The recent recalls of poultry and other products are not connected to the Boar's Head deli meat recall that sparked the nation's largest listeria outbreak in a decade this summer. That outbreak killed 10 people and sickened dozens more who ate deli meats processed at a Virginia plant that has since been permanently shut down. Bear’s Head also permanently discontinued its liverwurst product, where the listeria was first discovered.

Taylor Farms has issued a recall of several yellow onion products after 75 people were sickened and one died in connection with an E. coli outbreak linked to McDonald's quarter pounders. McDonald’s and the Food and Drug Administration have said preliminary reviews link the outbreak to raw, slivered onions served on hamburgers and several other fast food chains, including Taco Bell, Pizza Hut, KFC and Burger King, have stopped adding fresh onions to their items at certain locations. McDonald's has stopped selling quarter pounders at some locations in Colorado, Kansas, Utah, Wyoming, Idaho, Iowa, Missouri, Montana, Nebraska, Nevada, New Mexico and Oklahoma—about one fifth of it's U.S. locations. The onion recall is unrelated to the recent listera recalls.

Listeria is a foodborne illness most often contracted by eating improperly processed meats and unpasteurized milk products, as it spreads easily among deli equipment, surfaces, hands and food, according to the CDC. People who eat food contaminated with the listeria monocytogene bacteria can develop a listeriosis infection. Most healthy people don’t get seriously sick from a listeria infection, but it does disproportionately impact people older than 65, newborns and pregnant women—who may themselves experience only mild symptoms, but babies in utero can die from listeria. Pregnant women are 18 times more likely to get listeriosis than other healthy adults. The listeria bacteria can survive refrigeration and even freezing, making it difficult to eradicate once found.

2. There have been two listeria outbreaks related to contaminated food products so far this year. Two people died and 26 were sickened in connection to a queso fresco and cotija cheese contamination in February. The Boar's Head recall led to 59 cases and 10 deaths over the summer. There were three listeria outbreaks in 2023, according to the Centers for Disease Control and Prevention, linked to leafy greens, ice cream and fruit.
