Rumor: Dirty soda cans cause deadly diseases

Is dirt and bacteria found on soda cans causing deadly diseases?

Can dirt, bacteria and rat urine found on aluminum soda cans really cause deadly diseases, including leptospirosis?

An early iteration of the email claims a study was conducted in Spain showing that the tops of soda cans are "more contaminated than public toilets"; another claims the study was done at "NYCU." According to Yahoo!, the acronym NYCU is shared by New York City Underground, News You Can Use and North Yorkshire Credit Union, and none claimed credit for the announcement.
