The meals may be contaminated with the same strain of listeria that caused an outbreak tied to chicken fettuccine Alfredo sold at Walmart and Kroger stores. Four people were killed and at least 20 were sickened in the outbreak updated by federal health officials on Friday evening. The outbreak led to a large recall this summer.

Walmart said Wednesday that it plans to remove synthetic food dyes and 30 other ingredients, including some preservatives, artificial sweeteners and fat substitutes, from its store brands sold in the United States by January 2027.
