No, it won’t hurt. The ‘Do Not Eat’ packets just contain some silica gel (food grade when in food products) which is a desiccant and removes any moisture left over from packaging the product. It is included since it is very inexpensive, lessens the chance of food spoilage, and keeps packaged goods tasting fresher.
I wouldn’t advise eating it, but it isn’t harmful in any reactive way. It is non-toxic, non-flammable, and non-reactive (chemically) in a normal environment.
