Halal meat in Birmingham found to contain pork
Pork extracts have been found in a halal meat product during tests carried out by Birmingham City Council.
The council said the pork was found in packs of 20 Humza brand chicken burgers with a best before date of 10 May 2013.
There is no evidence to suggest Roshan Foods, which distributed the product, caused the contamination, a spokesperson said.
The council said it was working closely with other local authorities to trace "where and how this has occurred".
The pork extracts were found while checking for adulteration with horsemeat or other non-specified meat species, the spokesperson added.
The council said investigations were "on-going" and the Birmingham-based company involved was "co-operating fully".
Its retail and catering customers have been notified and a product recall has started, the council said.
A spokesperson said further sampling on other products distributed by the company had been carried out and the results should be known "by the end of next week".
