Buckwheat groats quality declines

Buckwheat turned to shit recently, is it crop shortages or improper storage/transportation? It also smells different...
Both Ukrainian & Russian buckwheat from current crops.
I can't bear eating even a spoon. Are they using some new pesticide chemicals?
If there is new chemicals used, why everything else hasn't changed its smell/texture/etc? Mystery is afoot.

Foreign matter has been found in five unused vials of Pfizer Inc.’s COVID-19 vaccine in two cities near Tokyo and one in Osaka Prefecture, local governments said Tuesday.

The vials containing a white floating matter belong to the same lot, FF5357, according to the cities of Sagamihara and Kamakura, both in Kanagawa Prefecture, and Sakai in western Japan.

The three cities have asked Pfizer to analyze the substances.

The contaminants were discovered at three vaccination sites in Sagamihara between Saturday and Tuesday, one site in Kamakura on Sunday and one site in Sakai on Tuesday.
