The USDA has kept raccoon rabies out of the central United States for over 30 years by air-dropping fish-flavored ravioli from helicopters. Each one is a small packet coated in fishmeal with an oral rabies vaccine inside. Raccoons, foxes, coyotes, and skunks find them by smell, bite through, and swallow. Many animals that consume the bait develop immunity, helping build a protective barrier across populations. The bait is generally considered safe for pets and tested in many non-target species. The USDA's Wildlife Services has been running this since 1995. Without the bait program, raccoon rabies very likely would have spread much further west. A federal program you've probably never heard of is protecting your pets and your kids by feeding wild animals ravioli from a helicopter.
