No clear answers on recent Spinach e-coli cause

Although a recent e-coli bacterial outbreak has been traced to spinach from a single California field processed on a single day, the actual cause of the outbreak still has not been determined based on a report just released this past Friday.

It's also unknown exactly how much spinach actually became contaminated. The report did state several possible causes of the contamination -- from tainted water to wild pigs roaming the area.

Will we ever know the cause of the e-coli that made at least 205 people sick and caused three deaths? The problem of quality control is sliding these days it would appear, even within the pet food industry's inclusion of rat poison into dog and cat food. Perhaps we should all grow our own gardens?
