Mayonnaise: Harmless or a Hidden Risk?
Mayonnaise feels safe and creamy, but mishandling it can quickly turn it into a hidden danger in your kitchen. Left out too long, whether on the counter or in the fridge door, bacteria can multiply fast—especially in homemade versions.
Commercial Mayonnaise: Safer Than You Think
Most store-bought mayonnaise is designed to resist bacterial growth thanks to pasteurized eggs and added acids. But safety depends on proper handling. Each dip of a spoon or knife introduces new microbes, and leaving the jar out for more than two hours—especially in a warm kitchen—can let those microbes multiply to unsafe levels. Keeping mayonnaise stored consistently below 40°F (4°C) is key to preventing contamination.
Homemade Mayonnaise: Extra Care Needed
Homemade mayo is even riskier. Made with raw or lightly cooked eggs and without preservatives, it’s highly vulnerable to bacteria. Always refrigerate immediately, use clean utensils, seal the jar tightly, and consume within a few days. Watch for changes in smell, texture, or color—if anything seems off, throw it out. No sandwich is worth a night of food poisoning.
Smart Handling for Safe Mayo
Treat mayonnaise with respect: refrigerate promptly, avoid temperature swings, and always use clean utensils. These simple steps keep your favorite condiment safe, fresh, and worry-free.
