Pesach Quinoa at Shoprite in Paramus
Shoprite has definitely stepped up their Pesach game, now including a special Kitnyos shelf (hint...it's part of a wider shelf closer to the plastic goods/foil/bags aisle.
I saw quinoa under some Israeli haschgacha.
Quinoa is quinoa, but some may be packaged at locations where other grains are processed and, therefore, cannot be absolutely assured of being chametz-free (just like every other thing in the kosher world, if no one is there to observe then there isn't 100% certainty). The quinoa that's approved for pesach use has also been certified as having been packaged under proper conditions (in past years there have not been any special markings, only an acknowledgment (on the OU orCRC websites) that the facility has been checked).
