FDA raises Lay's potato chips recall to highest risk level over undeclared milk

The FDA has upgraded its recall of Lay's potato chips to the highest risk level due to "undeclared milk," which can be dangerous for people with severe allergies. This recall was initially issued in December and now poses a greater health risk. In related news, a recall of Kirkland Brand eggs at Costco was also elevated to the highest risk level in late December, following a previous voluntary recall.
