Families were yesterday warned not to eat contaminated Irish pork products – but were not told which brands to avoid.
The Food Standards Agency issued the warning after it was revealed cancer-causing chemicals had been found in Irish pigs.

But it was unable to supply a list of banned sausages, ham, salami, pizzas or ready-meals.
Families were urged to check labels to see if food contains Irish-sourced pork. But many ready-meals do not say where the meat used comes from.
An FSA spokesman said: “We’re going as fast as we can to get a list.”
The pigs in the Irish pork panic were allegedly contaminated by feed made from stale bread that was still in its plastic wrappers.
It is believed the plastic-covered loaves were mulched down by a supplier who recycles bread and dough as animal feed.
An investigation is now concentrating on one mill in the Irish republic, which was closed down several days ago.
The mill, which has not been named, is thought to have supplied 10 pigs farms in the Republic and nine in Northern Ireland.
The scandal was revealed when tests on Irish pigs showed up to 200 times the safe level of dioxins – chemicals that can cause cancer.
The UK’s Food Standards Agency yesterday warned families not to eat Irish pork and ordered shops to remove all products
from shelves immediately.
But the FSA was unable to give a list of which brands use Irish pork and could not say when a
list would be made public.
Shops were yesterday still waiting to hear if Irish pig meat is used in leading sausage brands such as Wall’s, Porkinson, Pork Farm and Richmond. They are all owned by Irish firm Kerry Foods.
The FSA denied claims it had dragged its feet in issuing the warning after initial contamination fears were raised on November 19.
A spokesman said: “We are going as fast as we can and negotiating with Irish authorities to get a definitive list of what pork products can and cannot be eaten.”

Up to 80 per cent of fresh pork joints sold in Britain are produced here. The majority of imports come from Holland and Denmark.
But questions remain over sausages, sausage rolls, packs of cooked, sliced ham, salami and meat used as pizza toppings or in ready meals.
In many of these, consumers will be unable to discover the source of the meat simply by examining the labels. Lidl yesterday said half of its stores had already removed Irish-sourced “own-brand” black pudding and pork belly products from shelves.
Tesco’s has removed its own-brand Irish pork, bacon and sausages. Waitrose has withdrawn two sausage lines sold under Northern Irish celebrity chef Paul Rankin’s brand as a precaution.
Sainsbury’s and Marks & Spencer both said they do not use Irish pork in their fresh meat ranges but both stores were still carrying out an investigation. Between April and July, the UK imported 15,000 tons of pork and bacon from Ireland. Food safety experts yesterday said
the risk to health from the dioxins was small. Professor Hugh Pennington said: “You would have to have a lot of these compounds. You have to eat enormous amounts to haveany effect.”
Professor Alan Boobis, an adviser to the FSA, said dioxins take a long time to accumulate in the body, so a short period of exposure would have little impact.
He said: “One would have to be exposed to high levels for a long period of time before there would be a health risk.
“Even the levels detected in these pigs are extremely low and present no immediate cause for concern.”
The Irish government has ordered a recall of all pig products produced since September 1 because there is no way of determining which are contaminated.
The Republic’s farmers yesterday described the crisis as “Ireland’s foot-and-mouth.”
Tim Cullinan, chairman of the Irish Farmer’s Association, said the crisis was disaster for them.
He added: “It couldn't have come at a worse time, the weeks leading up to Christmas.”
Questions remain over sausages, sausage rolls, packs of cooked, sliced ham, salami and meat used as pizza toppings or in ready meals sold across the UK.
Up to 80 per cent of fresh pork joints sold in mainland Britain are home produced – the majority of imports come from Holland and Denmark.
