Yahoo Sports How Long Can Potato Salad Be Left At Room Temperature?
Potato salad is a familiar favorite that blends textures and tastes to strike a delicate balance of creamy, tangy, and savory, creating a satisfying and wholesome eating experience. The soft, tender potatoes and creamy dressing offer a hearty base, while the subtle crunch of finely diced vegetables, such as celery and onions, adds a refreshing contrast. The meld of flavors, from the richness of mayonnaise to the brightness of the mustard, results in a dish that is sure to be a standout side.
Because it is often featured at barbecues or picnics, there is the possibility that potato salad could be left out in the open for an extended period of time, which begs the question: How long can it last at room temperature?
The typically accepted range for room temperature is 68-74 degrees Fahrenheit. According to the FDA, perishables, such as mayonnaise-based potato salad, fall under the "two-hour rule" and should be refrigerated after two hours. That time frame tightens to one hour if the temperature outside is above 90 degrees Fahrenheit.

Bacterial Contamination Concerns
Potato salad can quickly become a breeding ground for bacterial growth when left at temperatures between 40 degrees and 140 degrees Fahrenheit, which the USDA Food Safety and Inspection Service calls the temperature "danger zone." Bacteria such as staphylococcus aureus and salmonella can rapidly multiply, even doubling every 20 minutes, when left at these unsafe temperatures.
The symptoms of foodborne illness can vary depending on the type of bacteria ingested and the individual's overall health. Common symptoms may include nausea, vomiting, stomach cramps, diarrhea, fever, and fatigue, which can present anytime within one to three days of consuming the contaminated item.
Surprisingly, the risk of foodborne illness from potato salad has less to do with the mayonnaise (the acid in mayo will generally prevent the growth of bacteria, the USDA says), and more to do with the potatoes. That's because cooked potatoes are prone to bacterial growth because of their water content and neutral or slightly acidic pH.
Ways To Keep Potato Salad Nice And Cold
It's clear why we want to avoid the temperature danger zone, but exactly how do you go about ensuring your potato salad is safe to consume? There are a few options available for keeping your dish nice and cold. First, be sure to refrigerate the potato salad right up until it has to be served and then right away again after everyone has gotten a scoop.
If you're in a picnic or barbecue situation, consider placing the potato salad bowl on a bed of ice to keep it cool. It's a good idea to put a layer of plastic over the ice so it doesn't melt and flood the potato salad. Alternatively, store the salad in a cooler with fresh ice or ice packs to keep the temperature down and the bacteria at bay.
Finally, consider a metal or foil serving tray or dish rather than a plastic one. Metal can stay cool longer than other materials, meaning more time for your potato salad to have its moment as the star of the show.
