The worst E. coli strains create shiga toxin so cooking is not sufficient since the toxin remains. 0157:H7 is the most dangerous of the E. coli strains. Sorry that my schedule has been such that I have not been able to keep up with these recently: In http://www.fsis.usda.gov/News_&_Events/2008_news_releases/index.asp you will find beef from multiple U.S. locations with this problem this month. Although not useful in this instance http://www.fda.gov/opacom/7alerts.html is also a site to bookmark.
