If we awarded a gross-out prize based on a health inspection document, a Family Dollar Store in West Philadelphia would have claimed it this week. For the first time in the (short) history of Clean Plates, we found "strong smell of rodent urine" recorded on an official report. The variety store, on the 5700 block of Baltimore Ave., also was cited on Nov. 4 for "substantial rodent feces" and gnawed packages of chocolate and cookies. Eeeew. Neither the store or its corporate management could be reached for comment.
