ELK lasagnes have been taken off the shelves in Ikea, Valley Park, after traces of pork were found in Belgium.
The dish should contain 100 per cent elk meat, a type of moose, considered something of a Swedish delicacy, according to an Ikea spokesman.
But test results confirmed that one European batch of Lasagne ÄLG in fact contained 1.4 per cent pork.
Ikea issued a 'sales stop', withdrawing around 18,000 of its elk lasagnes from 18 European countries, including all UK stores, until the matter has been fully investigated.
An Ikea spokesman said concerned customers could return any Lasagne ÄLG back to the Croydon branch for a refund.
"Pork does not pose any health risks," he said.
"However, we do not tolerate any other ingredients than the ones stipulated in our recipes or specifications, secured through set standards, certifications and product analysis by accredited laboratories."
It is the latest scare to hit the chain after almond cake with chocolate and butterscotch was removed from stores last month after traces of bacteria linked with human excrement were found.
Meatballs and hotdogs were withdrawn earlier after some traces of horsemeat were found.
Ikea said it was developing a comprehensive standard with requirements on traceability, slaughter, deboning and processing of meat products.
"The standard is developed together with a quality assurance company, SGS, and is expected to be ready before the end of April 2013," a statement said.
"The standard will be implemented during the next six months. Announced and unannounced audits together with tests and documentation will secure compliance."
