This may be something to discuss with your allergist, as the level of concern for each child may be different based upon past reactions.
For example, my son has reacted to what must be very small amounts of cross-contamination in cereal, salad dressing, chocolate chips, etc that did not have any warning labels but were made in a facility or possibly on the same equipment as foods with nuts/ peanuts. He also had an anaphylactic reaction ata restauant from cross- contamination, so we avoid foods with warning labels, even if we used to consider them safe. Oreos, for example, are manufactured different now, and we avoid them. We avoid anything that has any kind of warning label.
Some of his friends with nut allergies have a much higher tolerance and can pretty much eat anything unless it actually contains nuts as an ingredient. Their parents don't ban foods with warning labels unless they " may contain" nuts or peanuts, and sometimes not even then.
So it is very individual. Personally, I tend to think that if there is a warning, there may exist a possibility of cross contamination, so we avoi due to my son's past reactions.
