We seem to do lettuce better than the US...

I know we have an occasional fresh vegetable/fruit contamination issue, but the US seems to have an awful lot of incidents like this:

Federal health officials are urging consumers to stop eating romaine lettuce and asking industry to halt all sales amid an extensive E. coli outbreak unfolding across the U.S. and Canada.

Even the Americans seem to acknowledge this happens way too often:

“CDC and FDA did the right thing and gave a very broad warning to consumers. Hopefully they will find the source of the contamination and the cause quickly,” said Sandra Eskin, director of food safety at the Pew Charitable Trusts.
“We have seen so many leafy green outbreaks over the last year — it is really undermining consumer confidence in the safety of these otherwise healthy products,” Eskin added.
