After three years of heated debate, the Park Slope Food Coop is at last ready for a vote.

That is, a vote on if, in fact, there should be a vote at all.

Next month, the 15,500-plus member cooperative will decide whether to hold a referendum on what may be the most controversial issue in its nearly 40-year history: a boycott of products made in Israel.

The boycott—which has dominated the coop's newsletter with back-and-forth letters for months—is expected to draw as many as 1,000 people, forcing co-op staff to look for an alternative meeting location.

The co-op's manager, Joe Holtz, said the March 27 meeting will be held in the auditorium of Brooklyn Technical High School in Fort Greene. The co-op normally holds its monthly meetings in a synagogue with a capacity of about 400 people, said Mr. Holtz.
