Do I have for or poisoning symptoms?

[jennifer_bloom]

Yesterday I ate some outdated vegetables and some cheese that had been in the fridge for 4 days after being removed from the package and I began the afternoon with light nausea, dehydration, and than a slight stomach pain. I ignored it assuming it was too much fibre or morning coffee, but curious if it’s caused by bacteria. I’m in very good health so I usually don’t mind slightly expired food since I never get sick.

The cheese should still be good if it was refrigerated.
Did the vegetables have a date that was a "Best before" or a "Use before" If it was a Best Before date, that just means it at be a little less tasty after that date. A Use Before date is critical. The food usually spoils on or very soon after that date: milk sours, bread starts to mold.
Hope you get to feeling better soon.

Speaking a former culinary student it’s quite possible

I'd think the foods you mentioned wouldn't be the cause of your symptoms, cheese/veggies even if outdated, don't know where in the world you live but been hearing from local friends "New Orleans area" coming down with terrible stomach issues due to a virus, I'll pray for your speedy relief!

UNless the food you ate was growing hair ot had a rally ripe odor they probably were not the cause of your discomfort. Hope you feel better soon.
