After analysis the finding, we find that the % for red rice with insect is higher than the others.
For the PO OGIL2014/ 0525, we find that there is 2 packed date for the red rice, one is "packed date : 16-06-2014/ best before 15-06-2015" and the others is "packed date : 26-08-2014/ best before 25-08-2015". The insects are occurred insides the bag with best before date 15-06-2015 only. For the best before date of 25-08-2015, it is no insect at this moment.
We wonder if the insects are affected by the packed day. Also, it seems that the insects are occurred in red rice only. For the others, we believe it is the exceptional case. Some of the red rice under this PO is sold to our customer when the product is just arrived (no insect at that moment), we are now receiving the complaint from customer and they find that more and more insects are occurred.
