All, most or part of the odor will be gone. A short time, 30 minutes, of 'air' drying back in the refrigerator should also help to dissipate the odor. You may, or may not, still have a slight odor, but don't worry about it. Dry aged beef has a 'musty' odor that's hard to get rid also.
In fact more people die from wasp and bee stings than from snake bites. http://www.idahogeocachers.org/images/graphics/rattler.jpg (broken link) The only poisonous snake found in Idaho is the Rattlesnake. Rattlesnakes bite their victims with fangs that are hinged to swing downward from the snake's upper jaw. Venom is injected into the victim through grooves along the fangs.
The Snake River in Idaho now has an established population that is extending its range upstream to Lewiston as impoundments are completed (Simpson and Wallace 1978; Idaho Fish and Game 1990). No date was found to indicate when American Shad were introduced to this river. Two hundred shad from the Hudson River were stocked in Lake Michigan at Chicago, Illinois, in 1871 (a joint venture between the New York and California Fish Commissions) (Smith 1896).
