A HULL firm has responded to allegations it imported beef contaminated with horse from Poland.
Flexi Foods, in Inglemire Lane, sold the meat to Irish company McAdam Foods.
Tests in September showed samples contained up to 80 per cent horse.
The scandal has led to burgers being withdrawn from the shelves of Tesco, Asda, the Co-Op and Sainsbury's.
A spokeswoman for Rradar, a law firm acting for Flexi Foods, said: "We are aware of an on-going, wide-ranging Food Standard Agency investigation.
"We have been asked to supply some information in relation to only one part of this investigation, with which we are quite voluntarily co-operating.
"We feel it would not be fair, nor appropriate, to comment any further whilst the authorities continue with their much wider investigations."
