Twin DNA Test
DNA testing is the most accurate method to determine if twins are identical or fraternal. Since 1994, Affiliated Genetics has performed more twin zygosity tests for physicians, researchers and the public than any other laboratory. We are one of less than 50 laboratories in the world accredited to perform relationship testing.

The British government cannot be sure there is no safety risk from supermarket beef products that have been found to contain horse DNA, the head of the UK's leading official food control laboratory has warned.

Responding to the growing scandal over the contamination of burgers with horse and pig meat, which saw the first of the factories at the heart of the row close its production lines on Friday, the former president of the association of public analysts, Dr Duncan Campbell, said: "All we know is it is not a beefburger. What is it? We don't know. Why was it picked up in Ireland and not the UK, and how long has it been going on? Until we know what the source is of the 'horse' or 'something derived from horse' that has been found in the beef products, we cannot be sure there is no food safety risk."

Dr Campbell is the chief public analyst for West Yorkshire and a leading expert on the quality of meat. He will carry out some of the testing as the official investigation into the horsemeat scandal develops.

He said that it was "a reflex" for the UK Food Standards Agency (FSA) to say there was no food safety aspect to scandals of this sort, despite the fact that the law has clearly been broken, which may also mean that it has been broken in other ways.

Dr Campbell questioned whether raw materials could be coming from slaughterhouses that were not approved for processing meat for human consumption, or from unfit horses destined for the knacker's yard but which had instead ended up in the human food chain.

There could also be risks around residues of medicines used for sick animals but not considered safe for the human food chain, he added.

The official investigation into how large numbers of beef products on sale in the UK and Ireland came to contain horse and pig DNA is now focusing on imported ingredients added to cheap burgers.

Industry insiders have told the Guardian they believe that an ingredient called "drind", dehydrated rind or skin, may be at the heart of the scandal. It is commonly used to bulk up cheap meat products.

Additives made from boiled hide or off-cuts of carcasses are typically used to bind in added fat and water and increase the protein levels of economy beef products that have a low meat content. These may legally be identified simply as "seasoning" on the label.

Expert warns over horse DNA

A district court judge who is a world expert in forensic DNA has called for a public debate on the use of familial DNA testing, as police reveal they have now used the "last resort" method 38 times.

Judge Arthur Tompkins, an honorary member of Interpol's DNA monitoring expert group, says there needs to be a debate about the technique - which involves crime-scene samples being compared to the national DNA databank to search for relatives of an offender - before the technique becomes even more widespread.

"The effect of it is to increase the footprint of the database without Parliament having legislated for that increased footprint," the Hamilton-based judge said.

Critics of the technique say it raises serious privacy issues and has the potential to subject entire families to "life-long genetic surveillance". It has been banned in parts of the US, where the Columbia Law Review says the practice is not "racially neutral" and has a disproportionate impact on minorities.

Police national headquarters released figures to the Sunday Star-Times showing that they have asked Environmental Science & Research (ESR) to search the DNA database for partial, familial matches on 38 occasions.

But the strike rate has been low - as a result of familial searches there were only two people convicted.

Police say the method is used only as a last resort when all other lines of inquiry have been exhausted.

Tompkins said familial testing raised many issues of privacy and ethics. "It means that you have to worry about not only what you're doing, but also what your brother and uncle and father and children do. It means that people become involved in a police investigation solely on the basis of the genetic link."

The procedure could also cause conflict within families, revealing previously unknown relationships.

Tompkins said different jurisdictions treated the technology differently - it was banned in Canada and parts of the US but used without restriction in the UK.
