Potato salad, boiled potatoes, are a risky food to put out on a buffet, and even more so on a hot day at a picnic. If you’re going to make the potato salad at home, acids and cold temperatures are your friends, because bacteria grow slowly and poorly in an acidic environment at low temperatures.
What kind of bacteria is in potato salad?
Most of the bacteria that would inhabit your salad like oxygen, which there would be plenty of. However, if you’re using home-canned potatoes, botulism toxin, which is produced by bacteria in no-oxygen conditions, can be a concern.

What happens when potatoes are put in storage?
When potatoes are placed in storage, rapid cooling can result in more rot forming organisms in the tuber because the entry points remain unhealed. Rapid cooling, particularly in the absence of adequate air, can also result in black spot and other potato damage. Disease Growth and Infection
How does temperature affect the quality of potatoes?
The potato tuber reacts like any living organism; respiration increases with increasing temperatures. When the respiration increases so does the tuber weight loss. Since lower temperatures also maintain dormancy, keep temperatures as low as possible without otherwise decreasing quality (e.g., sugar buildup in processing potatoes).
