For food at least I think it may be somewhat amenable to some of the newer fingerprinting techniques (e.g. using DNA microarrays). I've been wondering why origin/content/quality validation for food based on actual biological science doesn't exist for years. I did biochemistry for undergrad, and some of those labs could be done in the average RV kitchen, and others could be packaged into test kits.
