Sure it passed. The detection limit was 25 becquerels/kg, testing done in 5 to 10 seconds at most using brand-new detectors built specifically for the task of rapidly "measuring" the radioactive cesium in rice grown in Fukushima Prefecture.
Never mind the details like that. Shoppers in Edogawa-ku, Tokyo (itself in the more contaminated section of Tokyo) are happy to snap up this year's fresh crop.
From Nikkei Shinbun quoting Kyodo News (9/1/2012; emphasis is mine):
New crop of Fukushima rice sale started in Tokyo, all bags passed the inspection [for radioactive materials]
New crop of rice harvested in Fukushima Prefecture this year started on September 1 at "Fukushima Market", a shop to test selling the Fukushima produce in Edogawa-ku, Tokyo. Fukushima Prefecture has started testing all bags of rice for radioactive materials since August, and this was the first sale of the rice that passed the test outside Fukushima.
Bags of rice from Motomiya City and from Aizubange-machi, both of which tested below the detection limit (25 becquerels/kg) were put on sale. Shoppers were sampling at a sampling corner of the store, and seen purchasing [the rice] together with the peaches from Fukushima.
Mr. Takao Okamoto (age 45), an office worker who lives in Edogawa-ku, was visiting the shop with his family of four. He [said] he had been a fan of Fukushima rice even before the March 11, 2011 disaster. He said, "[The rice] tastes great this year, too. They test the rice, so I bought without any worries at all."
