Because it\u2019s made with pasteurized eggs and added acids, it\u2019s designed to resist bacterial growth\u2014yet that protection has limits. Once opened, every dip of a spoon or knife introduces new microbes. If the jar is then left out for more than two hours, especially in a warm kitchen, those microbes can multiply to dangerous levels. Storing it consistently below 40\u00b0F (4\u00b0C) is essential to slow this process.<\/p>\n<div class=\"code-block code-block-4\"><\/div>\n<p>Homemade mayonnaise demands even more caution. Without preservatives and often made with raw or lightly cooked eggs, it\u2019s far more vulnerable to contamination and should go straight into the refrigerator and be used within a few days. Always use clean utensils, close the lid tightly, avoid temperature swings, and when in doubt about smell, texture, or color, throw it away.
