Alternative Method for Checking Rice and Other Grains
- Visually scan the product and look for obvious signs of infestations (weevils, worms, and/or webbing). If you find signs of infestation, then discard (or return) the product. If no infestation is found, then continue with the next step.
- Place the rice/grains in a household sieve and then agitate the sieve while holding it over a light box or sheet of white paper.
- Carefully scrutinize the light box or sheet of paper.
- If you find any infestation whatsoever, then discard (or return) the product. If there is no infestation, then the product may be used.
