Bee, wasp venom shortage could be dangerous for those with allergies
As summer begins, signaling peak time for insect stings, allergists across the U.S. are warning of a shortage of a little-known but crucial product -- honeybee, hornet and wasp venom extracts used in shots that prevent life-threatening reactions. Supplies of the extracts -- which are made from venom gathered by hand from millions of individual insects -- have been scarce since October. That's when one of two manufacturers in the U.S. shut down production after contamination problems.
