Question:
Hi
Is eating off a metal utensil that had cold non kosher food on it over 24 hours ago a problem?
Answer:
Hi,
If the food was cold, before or after 24 hours is the same. The concern here is if there is any residue left over from the non-kosher food. If the area is cleaned well, it is permitted, although it is preferable to put something down on the surface.
Best wishes
