You're being systematically lied to. Produce CAN be purified. I've opened a new yahoo account named "purifyproduce." Write to me, for free info. I am selling absolutely NOTHING.
I live in Mexico and have purified for 14 years. All of Mexico has been purifying for decades. YOU CAN'T. And now somebody is deliberately tainting first spinach and then, tomatoes. Write to me. Then spread this info around! It's time this deliberate sabotage was investigated.
I'm supremely outraged.
