For those buying dates, please look on the packet for the country of origin. If you don't see it stated. Avoid them.
If you'd like to compound on your feel good factor. How about Zaytoun dates which are a non profit company supporting farmers of Palestine.
Go even further and purchase them from MADE in Europe. A organisation promoting green issues.
