(CNN) A record haul of cocaine has been discovered in crates of bananas at supermarkets in northern Germany.

The cocaine -- amounting to hundreds of kilograms -- was found on Wednesday in banana crates in six branches of the Aldi supermarket in the northern city of Rostock, and at an Aldi logistics center in Jarmen.

The drugs are believed to have originated in Latin America, Harald Nowack, spokesman for the public prosecutor's office in Rostock, said.

"The packages were temporarily secured and subsequently separated from the remaining contents (bananas)," he said.

Large hauls of cocaine were found at Rostock port in 1992 and 2005.

While the total amount of drugs recovered is still be determined, Nowack told the German news organization NDR that the haul was "really unique" for the state of Mecklenburg-Vorpommern in northeast Germany.
