Inedible

On my way to work the other day I passed by a familiar ice cream stand with the obligatory dumpster & barrels behind it. What I want to know is, is it truly necessary to label these metal barrels "inedible"? Is this really a problem? Do people really crack the top of it, peer in & think, "Yum! There's good stuff in there!" and dip their ladle in for a taste of old grease or whatever biohazard may lurk in there? I can barely go near the dumpsters behind the four-star restaurant below our office without gagging, much less ponder a treat from a baked-in-the-sun, oversized grease jar.
