Aldi is the latest company to drop food supplier Silvercrest.
Aldi has become the latest major supermarket to withdraw a frozen burger contract with an Irish Republic food supplier linked to the horsemeat row.
Large amounts of horsemeat were found in some burger samples manufactured at the Silvercrest plant in County Monaghan, which supplied Aldi Ireland.
Both Tesco and the Co-op have already dropped Silvercrest as a supplier.
Aldi UK has suspended its contract with British firm Dalepak after traces of horse DNA were found in its burgers.
Both Dalepak based near Northallerton in North Yorkshire and Silvercrest are part of the ABP Food Group.
Aldi Ireland said it was necessary to terminate its contract with Silvercrest “due to a serious breach of contract”.
“An internal Aldi investigation into the matter is ongoing,” it said.
Burger King has dropped Silvercrest as a supplier, saying it had provided the chain with a “small percentage of beef imported from a non-approved supplier in Poland”.
It said Silvercrest’s failure to deliver 100% British and Irish beef was a “clear violation of our specifications” and was in breach of its contract.
Burger King added that tests on food sold at its restaurants had discovered no equine DNA.
