If there is a container of cold, pareve food (such as a bag of flour or a jar of peanut butter), does using a clean dairy or meat utensil to scoop out some amount of the product cause the _remainder_ of the product in the container to become dairy or meat? Does the material of the utensil matter? Does it matter whether the utensil is a spoon or a knife (e.g. for peanut butter)?
Related, but not quite the same questions:
If the knife or spoon was clean and the ffod was cold, the food is still pareve, as the item is not a davar charif, and no taste was imparted.
