Updated 2:14 p.m. with a correction issued by the Associated Press. Corrects Missouri figure to "just more than 2,000," not "nearly 3,000."
An Associated Press survey of the nation's top methamphetamine-producing states shows national lab seizures rose again last year - and Missouri is, again, at the top of the list.
The survey confirmed that Missouri regained the top spot for lab seizures in 2011 with just more than 2,000 busts. It also found that Tennessee came in second with almost 1,700, followed by Indiana, Kentucky and Oklahoma.
Tennessee overtook Missouri last year.
Federal data the AP obtained this week from the Drug Enforcement Administration appeared to show meth lab seizures remained about even during the past two years. But totals from the states surveyed by AP are higher.
The numbers combined indicate nationwide meth lab seizures actually rose at least 8.3 percent in 2011 compared to 2010.
The AP polled the states after determining that several had not yet reported full-year data to the DEA.
