NDMA IS BACK IN ELMIRA

This time apparently it's on store shelves. What the hell. According to an on-line announcement NDMA (N-nitrosodimethylamine) has been found in the antacid medication Zantac. The active ingredient is known as Rantadine. This is an extremely common medication for those with excess stomach acid and can be purchased either over the counter or on prescription.

My understanding is that several agencies and companies around the world have recalled the product or pulled it from their shelves including right here at our local drugstore (Shoppers Drugs). That said authorities are advising consumers who have been prescribed Zantac/Rantidine not to over react and in fact to keep taking their medication however to contact their health provider for a possible substitute.

NDMA is a strong carcinogen and should not be in either the air, our food or our water. Obviously also not in our medications. How exactly has this occurred? How long has it been in Zantac? Why wasn't it discovered before now?
