My wife recently developed alot of food allergies, one of them are peanuts. They think it might be due to a latex allergy. She's been an operating room nurse for over 15 years and along with several coworkers, tested positive to latex. Latex has alot of potential cross-over allergies.
Now, except for a few necessary items, the operating rooms are virtually latex free.
Most of this happened about 2 years ago, bad times... many trips to the ER for allergic reactions but NONE since.
