In toxicology screenings of the 10 most borrowed books at the Antwerp library in Belgium, two Belgian university professors found traces of the herpes virus on copies of E.L James' "Fifty Shades of Grey."
That wasn't the only thing they found, although it was probably the most alarming.
Copies of all 10 most-borrowed books showed traces of cocaine -- not enough to have a "pharmacological effect" but enough to cause a person who touched the books to test positive for the drug, a toxicologist told Expatica.com.
Copies of one other title among the 10 most popular books also tested positive for herpes: "Tango" by Belgian writer Pieter Aspe.
The professors say the concentrations of the virus are so minimal that there is no public health risk and that library borrowers won't get herpes from the books.
