Canadian experts in E. coli bacteria say a mutant strain spreading across Europe is alarming in the way it keeps eluding scientists. “We could be seeing another Walkerton,” professor Keith Warriner of the University of Guelph said Thursday. “A water supply contaminated with sewage or manure.” Water is a likely culprit, agreed Dr. Herb Schellhorn, whose lab at McMaster University specializes in studying E. coli bacteria. “You think it would be fairly easy, but it isn’t,” said Schellhorn. “Any type of food that has water processing is a likely candidate.”

Really? because I thought that antibiotics & hormones for cattle/livestock was strictly forbidden to use in the European Union
I think it's banned over here my friend!
We're sleeping badly, and have bad dreams,' Kiemes says quietly. 'We can't get the images of suffering patients out of our heads.' The neurological breakdowns of patients are particularly concerning. 'When their condition gets worse, then it's dramatic.'
The patients become disoriented, have difficulty expressing themselves, suffer convulsions. Some become apathetic, others make strange noises. Some get such strong cramp attacks they have to be restrained. Since the first EHEC patients arrived in the hospital, the wards treating them have been on a 'complete emergency footing,' Kiemes says. Doctors and co-workers have worked through weekends and days off, delaying their holidays in order to help out. In daily meetings they examine the situation from all angles.
Doctors are battling in the dark, surprised by the length of the illness and its unpredictable developments.
Gastroenterologist Stefan Schreiber bemoans the fact that, despite intensive questioning about eating habits, there has as yet been no eureka moment, when doctors discover which food links the cases. 'It will only be over when we find the source of the infection and we don't have any infections for two, three weeks,' he says.
'It really annoys me that we still haven't found the cause.'

Scientist at Cambridge University have not only found a NEWER more RESISTANT strain of MRSA, they have also found it in cows milk there...and in people.
It is directly attributed to antibiotics being used in animals.
Not only that, but people in developing countries or in more "progressive" countries that still insist on eating everything (read every living damn thing, from bats, to poison fish, to frogs and fish) raw, or even alive, and strive for the most bizarre foods because they think it has some sort of super power, are also a source of problems.
European Union Bans Antibiotics for Growth Promotion
Europe is far ahead of the United States in the responsible use of antibiotics. On January 1, 2006, the European Union banned the feeding of all antibiotics and related drugs to livestock for growth promotion purposes. The sweeping new policy follows up a 1998 ban on the feeding of antibiotics that are valuable in human medicine to livestock for growth promotion. Now, no antibiotics can be used in European livestock for growth promotion purposes.
The use of antibiotics as growth promoters has been prohibited in the EU since January 1, 2006. Antibiotics had been added in low doses to the feed of farm animals for decades worldwide because they improved the growth rate and efficiency of conversion of feed into carcass meat in pigs, poultry and cattle. Their use increased average daily growth and food conversion ratios by 3 per cent to 11 per cent depending on species. The ban was the final step in the phasing out of antibiotics used for non-medicinal purposes in the EU and antibiotics are now only allowed to be added to animal feed for veterinary purposes. Antibiotics are still used widely as feed additives for growth promotion in many countries outside the EU.

Fresh vegetables are still the prime suspect, but Flemming Scheutz, head of the WHO Collaborative Centre for Reference and Research on Escherichia and Klebsiella in Copenhagen, suggests that the bacteria might not have originated in the food chain at all. "This strain has never been found in any animal, so it is possible that it could have come from straight from the environment into humans".
Lothar Wieler, a veterinary microbiologist at the Free University of Berlin, cautiously agrees with this theory. In addition to the antibiotic-resistance genes, the bacteria contain a gene for resistance to the mineral tellurite (tellurium dioxide).
Tellurium oxides were used as antimicrobial agents against diseases such as leprosy and tuberculosis before the development of antibiotics. Some strains of bacteria may have evolved resistance to tellurium during its historical medical use, or after its use in the mining and electronics industries increased its presence in the environment. According to Wieler, the strain's resistance characteristics could point towards an environmental source, such as water or soil.
