Solving the olive oil riddle

Is it extra virgin or not? Is it exposed to too much heat or light? Has it been improperly stored?

But the report itself might serve to confuse the issue, both because the sample was small and the findings were inconsistent from store to store. The North American Olive Oil Association, which represents most olive oil importers, disputed the findings, noting that its own testing found problems in only about 1 percent of samples.
