In the United States somebody found out he could solve the problem of hospital waste management by exporting the stuff to Brazil. Tons of it have been arriving in containers labeled "defective fabric." Among bloody bed sheets and dirty diapers - dirty with you-know-what - are used syringes and catheters.
The governor of Pernambuco, where the stuff landed, says the people responsible for the sale of hospital waste is the US customs agency and that he intends to get the Brazilian Ministry of Foreign Relations to do something about it.
Potential for chemical sterilization of prions
Prions are highly resistant to chemical sterilization. Treatment with aldehydes (e.g., formaldehyde) have actually been shown to increase prion resistance. Hydrogen peroxide (3%) for one hour was shown to be ineffective, providing less than 3 logs (10−3) reduction in contamination. Iodine, formaldehyde, glutaraldehyde and peracetic acid also fail this test (one hour treatment). Only chlorine, a phenolic compound, guanidinium thiocyanate, and sodium hydroxide (NaOH) reduce prion levels by more than 4 logs. Chlorine and NaOH are the most consistent agents for prions. Chlorine is too corrosive to use on certain objects. Sodium hydroxide has had many studies showing its effectiveness.
