       Sushi rice is vinegared and stored at a room
    temperature. A health department inspector came to a
    Japanese sushi restaurant, and he said that keeping
    sushi rice at a room temperature was a violation and
    the rice was thrown away. However, the sushi rice was
    made twice a day for lunch and dinner at this
    restaurant, and when the rice pH was 4.6 or below, it
    is not a hazardous food. The owner explained about
    sushi rice pH, but the inspector asked him to bring
    the rice to a laboratory and check the pH. At the
    laboratory, conducting a challenge test about
    sushi rice costs $2000-$5000 for various pH levels and
    storage temperatures. OR a 2-hr seminar costs $700 to
    teach the Japanese owners how to measure rice pH. A
    material fee of $30 per person will also be charged to
    measure their own rice.
       I think it's very expensive and there are other
    less expensive solutions. I propose to buy the pH
    kits and tell the owners how to measure their pH. I
    will provide a cost estimate shortly. Does someone
    have any good ideas?
