Rice has the arsenic because it's easily absorbed into the grain through the ground during growth.
Yes, I'm still eating it. There have been hundreds of scares over the years. Now is just another one. If we stopped eating everything that was flagged, there would hardly be anything left including those precious "clean" foods. I can't even keep count how many "clean" foods have been contaminated or condemned at one point or another.
Life is too short and worrying will kill you far faster than a naturally occuring toxin/mineral. Keep in mind, Rice has been a staple in Asian countries for 1,000s of years. They have one of the longest lifespans on earth. Enough said, I should think.
