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.

Cockroaches don't eat the new buckwheat. Wtf.
