Potlucks are one thing, but leftovers from potlucks..... In this case, 15 postal workers become ill after consuming leftovers from a potluck dinner held for 200 to honor veterans.
What was the issue? While the news reports are light on information, we can make a pretty good guess. First, no one got sick from the initial offering, but rather it was the nightshift workers who became ill after consuming the leftovers. The symptoms of vomiting and nausea were noted and it occurred about 6 hours or so after their shift began. The short duration from consumption to onset of the illness in conjunction with the symptoms of vomiting and nausea would indicate a Staphylococcus aureus intoxication. If that is the case, we could guess that some of the leftovers were not properly refrigerated.
