may be, but do they work, and have they been enforced ;

not much of a research program, but since they found contamination of one out of 16, this should merit further research ASAP.

[this would translate to, not enough human deaths yet, to change practice...TSS]
this is unfortunate for U.K. public, and could further spread the agent. did they research all the data?
why did SEAC refuse to look at the research put forth in the LANCET of Sept. 1996 on Pithing by Tam Garland of Texas A.M.?
>From what i understand they refused the data because the research was not done in the U.K.???
Who/Why would care, if the research proved that pithing could further spread the agent?
Which in fact, it showed a published color photo of 14.5 cm of brain tissue in the LUNG. It had already gone through the heart. In their unpublished work they found 16.5 cm of brain tissue in the LIVER which means it blew through the heart and lungs to arrive in arterial circulation.
Their views...unfortunately for U.K.
Q.-- Research on the risks of contamination by stunning and slaughter procedures?
A.-- A MAFF-funded team at Bristol University has been carrying out research on the possibility that stunning and slaughter procedures may cause cattle carcases to be contaminated by brain tissue. An article about this research was published in the Veterinary Record on 16 Oct. 1999.
Q.-- What does this research show?
A.-- The researchers were looking for signs of brain tissue in the jugular vein (the blood vessel draining the head) of cattle which had been stunned using various different methods. They found brain tissue in jugular venous blood of one animal which had been stunned by a method used in the UK. This was one of sixteen animals which had been stunned using a penetrative captive bolt gun followed by pithing. None of fifteen animals stunned by penetrative captive bolt without subsequent pithing showed any sign of brain material in their blood.
Q.-- What is the significance of this finding?
A.-- The research has found evidence that neural contamination of the blood could result from stunning and pithing. If traces of brain tissue can be transported via the blood stream to the edible parts of the carcase, there could be implications for human health in relation to BSE.
Q.-- Does this research show that beef is unsafe?
A.-- No. The research did not demonstrate that meat can be contaminated by traces of brain tissue in the blood. Before any brain fragments in venous blood could get into the arterial system, they would have to pass through a network of very fine blood vessels in the lungs. Only very small particles would in principle be capable of doing so.
Q.-- What is SEAC's advice?
A.-- SEAC have advised that there is no reason on the basis of current data to change the common UK practices of stunning and pithing during slaughter of cattle.
Q.-- Why did SEAC take this view?
A.-- SEAC's view was that * the finding of brain tissue in the venous blood in one of a group of sixteen cattle slaughtered by penetrating captive bolt pistol and subsequent pithing provides insufficient data to give an accurate assessment of the frequency of this occurrence;
* there are no data as to whether or not neural tissue reached the arterial circulation in the single positive animal; * the very low number of infected animals at the late stage of the incubation period entering the food chain means that there is no need to alter current slaughter practices.
Q.-- What methods of stunning are used in the UK?
A.-- Animals are stunned to ensure immediate unconsciousness which lasts until death by bleeding. Of abattoirs in the UK killing cattle for sale for human consumption, about 80% currently use a penetrating captive bolt with pithing and about 20% a penetrating captive bolt without pithing.
Q.-- What is pithing?
A.-- Pithing is the insertion of a rod into the brain through the hole made by the captive bolt. It destroys brain tissue and speeds up brain death. Pithing is carried out, before hoisting the animal, to reduce the involuntary kicking actions of the stunned animal.
Q.-- Why is pithing used?
A.-- Pithing has benefits for both the safety of abattoir workers and animal welfare as it reduces involuntary kicking by stunned animals and removes any risk that a stunned animal may regain consciousness........
