Public health officials are urging consumers to discard specific precooked pasta meals from Walmart and Trader Joe's due to potential Listeria contamination linked to a nationwide outbreak. The affected products, Marketside Linguine With Beef Meatballs & Marinara Sauce and Trader Joe's Cajun Style Blackened Chicken Breast Fettuccine Alfredo, share a Listeria strain with a deadly outbreak that has caused four deaths and at least 20 illnesses. Authorities recommend thorough cleaning of refrigerators and surfaces after disposal. Investigations are ongoing to identify further affected products.
