Million jars of peanut butter dumped

A million jars of peanut butter have been dumped in a US landfill after the company they were meant for refused to take delivery or donate them.

Nearly a million jars of peanut butter are being dumped at a US landfill to expedite the sale of a bankrupt peanut-processing plant that was at the heart of a 2012 salmonella outbreak and nationwide recall.

Bankruptcy trustee Clarke Coll said he had no other choice after Costco Wholesale refused to take shipment of the Sunland Inc product and declined requests to let it be donated to food banks or repackaged or sold to brokers who provide food to institutions like prisons.

"We considered all options," Coll said. "They didn't agree."

Costco officials did not return telephone calls seeking comment. But court filings indicate the product was made with $US2.8 million ($A3.03 million) worth of Valencia peanuts owned by Costco and had been sitting in the warehouse since the company shut down and filed for bankruptcy last northern autumn.

After extensive testing, Costco agreed to a court order authorising the trustee to sell it the peanut butter. But after getting eight loads, Costco rejected it as "not merchantable" because of leaky peanut oil.

Coll said "all parties agreed there's nothing wrong with the peanut butter from a health and safety issue", but court records show that on a March 19 conference call Costco said "it would not agree to any disposition ... other than destruction".

So instead of selling or donating the peanut butter, with a value estimated at $US2.6 million, the estate is paying about $US60,000 to haul the 950,000 jars of nut butter - or about 25 tons - to the Curry County landfill in Clovis, New Mexico, where public works director Clint Bunch says it "will go in with our regular waste and covered with dirt".

The last of 58 truckloads was expected on Friday, he said.

Sunland made peanut butter under a number of different labels for retailers such as Costco, Kroger and Trader Joe's, along with products under its own name. But the plant was shut down in September 2012 after its products were linked to 41 salmonella cases in 20 states.

It later reopened for about five months, but shut down last October after the company's Chapter 7 bankruptcy filing.
