I left a bottle of garlic stuffed olives out overnight. Are these still safe to eat?
Traditional pickles made with brine and vinegar are very hardy, and where used in the days before refrigeration to store food over many months
The secret is to only use a very clean utensil to remove a single daily portion from the main storage vessel, and otherwise keep the main storage vessel tightly closed and in a cool and dark location
With modern pickles, who knows? Read the side of the jar, if it seems to have a decent amount of salt and/or vinegar it should be just fine
If you haven't put dirty utensils or your hands in it, it will last a long time (weeks or months, depending on the ambient temperature level)
Otherwise, just keep them in the fridge :-)
