Today I sampled a 50 pound bag of rice
stored outside for 7 years.
What I discovered:
It had some dead tiny bugs in the bag, I assume a type of weavol.
My understanding is they are in all large bags of rice.
Other than that the rice looked like rice.
How I sampled it:
I took a 1 cup sample and steamed it.
First I hand removed the dead bugs,
Then shook all of the rice in a fine filter to remove
dust and bug parts(?).
Then I added water for steaming.
I agitated the water for remaining bugs to raise topside
and I filtered them out.
I steamed it and compared the cooked rice with some leftover in the Frig.
There was no difference in odor, texture or taste.
Note: I never washed off the sprayed on nutrients.
I cut a hole in a 4 foot cubic ICB plastic tote.
I stacked (34) 50 Lb. bags in it and sealed it
with duck tape and put a layer of rubber sealant over the door joints.
The cube was stacked under a pole barn with one side shielding the Southern sun (in Florida).
