STAR-K recommends that ALL barley be checked prior to usage, even when there is a hechsher on the package. Infestation issues arise from improper storage, which is beyond the control of any hashgacha.
To check barley, STAR-K says to follow these steps:
- Place all the barley you wish to use in a white bowl.
- Fill the bowl with water, a few inches over the top of the barley.
- Allow to sit for 15-20 minutes.
- If there are insects present, they will float to the top.
STAR-K has posted images of insects commonly found in barley, and its full Check For Insects page covers other produce and foods.
The reminder comes as yoshon season gets underway. TLS reported earlier this week that STAR-K released its 5787 Quick Reference Guide.
