Supermarket operator Great Atlantic & Pacific Tea Co. has concluded the second round of auctions for its remaining stores, with Best Yet Market the winning bidder for a Waldbaum's in Commack and a Pathmark in East Rockaway, union officials said.

Mineola-based United Food and Commercial Workers International Union Local 338 Friday announced the Commack bid, which was confirmed by a spokeswoman at Best Yet Market, a family-owned nonunion operator based in Bethpage, with 16 stores on Long Island.

Separately, Westbury-based UFCW Local 1500 announced Best Yet's East Rockaway bid to its members Thursday.

Local 338 has about 2,200 members who work at 32 Waldbaum's stores on Long Island. Local 1500 has about 1,500 members at 19 Pathmarks on Long Island. "We are still contacting and meeting with union employers every day in an effort to find buyers for our remaining stores and keep as many of you working as we can," according to the Local 1500 blog post to its members.

An A&P spokesman declined to comment.

Best Yet Market had successfully bid last week on two Waldbaum's in Merrick and Westhampton Beach. The company said Friday it plans to renovate the stores as needed with new equipment, floors, ceilings and lighting.

So far, 27 Long Island stores have been bought or bid on and five are scheduled to close, according to union documents and court records. Another 19 stores remain available to buyers who contact A&P before Oct. 16. Another round of auctions could be scheduled as needed, union officials said.

"We do not know if any further auctions or sales will occur and it is likely that all unsold stores will close within the coming weeks," said a statement by UFCW International. "Our primary focus going forward will be helping any members and their families who may be facing displacement."

Winning bids are not final until they are approved by the bankruptcy court.

A hearing is scheduled for Oct. 16.
