I cooked a pareve food in a dairy pot and accidentally served it with meat

I cooked something parve in a Dairy pot and then I accidentally served it with meat and everything was hot do I need to caser the plate the fork whatever it was eaten with so it depends if we're dealing with a non-spicy item let's say just a regular potato then although we consider the potato that was cooked in the dairy pot to be Dairy that is just really a stringency in fact would consider it to be par they would say one could serve it with meat however the custom of ashm is to treat it as dairy but that's only before the fact so meaning one should not serve it together with meat but if one did then after the fact if it's already mixed with meat we consider it to be py Tu and one can eat the food there's certainly no need to cash or anything or throw anything else out however if it was indeed a spicy food such as an onion that was cooked in the dairy pot that's a serious question one should consult with the rabbi it's possible in fact one might need to prasher or throw out the plate
