poison control, although that sounds harmless, one time my daughter ate a bag of silica gel, you know those packets inside purses and shoes that say "do not eat" on them. Well poison control was a big help when i called, they informed me that those are not toxic and are merely like baking soda infused pellets to remove odor. They say "do not eat" because they are considered a choking hazard if they were to clump together somehow. Poison control employees are basically just sitting there waiting on calls like yours, with access to a large database of information. They will even call ahead to your local hospital if the ingestion is that serious.
