Bests & Worsts Reviews from Amazon

So, the product -'Raw Brazil Nuts 32oz (2 Pounds) Distinct and Superior to Organic, No PPO, Probiotic, Large,Fresh and Reasealable bag' being an 'Amazon's Choice' arrived. There is nothing in the package or on the bag stating the origin of these nuts. There is also no certification explaining product quality. It is just a bag of nuts - could come from anywhere. I then discovered they could not be returned - but Amazon easily gave me a refund (gift card) and told me I could keep the nuts. So, we'll see if the squirrels like shelled brazil nuts - we won't eat them. Never got an explanation as to how they could be Amazon's choice with no documentation or certification?
