Have a look at this (particularly unpleasant) headline and standfirst, and then have a look at the full story on WESH.com.
First, the headline: "Human waste found in soda fountains". Well, the body copy says the fountains "contained coliform bacteria, which is a group indicative of fecal contamination". But it doesn't say anything about actual human waste being found.
And then the standfirst: "Virginia researchers find 70 percent of drinks contaminated". The body copy says "nearly half of all beverages" contained the bacteria - so where does this figure of 70% fit in?
Incidentally, the story refers to "a study" carried out by "experts" and "researchers", and also indirectly quotes "microbiologists". Names and details, please!
