The practice, banned in the EU since 2000 following the spread of bovine spongiform encephalopathy (BSE), is likely to alarm the public and processors, who are only just beginning to recover from the crisis.
The European Economic and Social Committee, an EU advisory group, is spending €1.7 million to fund research programmes by 12 scientific institutes across the bloc.
A minute from the committee says that pig meal should be allowed for chickens and that chicken remains should be fed to pigs.
"The EESC suggests that the European Commission pursue and step up as swiftly as possible the studies currently under way which clearly show that the use of meat meal from nonruminants can be used in pig and poultry feed without posing any danger to human health," it reads.
In UK, where the BSE crisis began and was more severe, the Department for Environment Food and Rural Affairs (Defra) today confirmed that they were aware of the studies, but had no involvement.
The spread of BSE has been linked to using infected animal remains as feed for cattle.
Since the first discovery of the disease in the UK in 1986, some 190,000 cases have been reported worldwide, according to World Organisation for Animal Health (OIE) statistics.
Scientists believe that the human illness, Variant Creutzfeldt-Jakob Disease (vCJD) - recognised in 1996 - is caused by the consumption of BSE-infected meat.
In 2006, there were 114 known cases of BSE in Britain, and there have been 24 so far this year. In May 2006, European restrictions were eased for UK beef exports into the bloc.
The ban was lifted as cases of BSE dropped in the UK. Before the BSE crisis in 1986, the UK's beef exports were worth about £1bn (€1.5bn) compared to £20m (€29m) in 2004, according to the consultancy Food from Britain .
