In comparison, SIGG bottles faired extremely well. Based on this analytical method, the limit of quantitation (LOQ) for BPA was approximately 2ppb. The LOQ is the level of BPA that can be determined reliably in these samples. Even under these extreme temperature conditions, no BPA was detectable in the SIGG bottles above this LOQ.
"Beer usually replaced water as the daily drink. An early morning tankard of beer was typical in colonial America, even for children. This tradition...came from England. The Pilgrims loaded more beer than water on the Mayflower. And, there is some evidence that they were put off at Plymouth, rather than Virginia, because the ship's crew wished to make sure they had enough beer to consume on the return voyage."
At first, these discoveries emerged by accident, when test tubes and petri dishes in laboratories were switched from glass to plastic. A group of Stanford researchers in 1993 found that breast-cancer cells it was studying reacted with a mysterious estrogen, which it traced to polycarbonate lab flasks. A few years later, Patricia Hunt, a geneticist at Case Western Reserve University, discovered abnormalities in the chromosomes of her lab mice. She eventually concluded that damaged polycarbonate cages were at fault.This article says "damaged" but the story I heard is that they had a new lab assistant that (depending on the source) either 1) used an alkaline cleaner or 2) scrubbed the cages harder than the previous assistant had.

Is there a way to check the manufacturing date on a Sigg bottle?
