The influential "food poisoning lawyer Bill Marler has published a new extensive article on MRSA, including MRSA st398.
His article, as one might expect, includes comment on transmission to humans via food, including a case study. It contains information previously unknown.
In an article, sometimes reading like a roll call of the United Nations, Britain is, as usual, missing.
Even for those naive enough to believe the assurances given by Defra, the British agricultural ministry renamed after the Mad Cow scandal, that British livestock is clear of MRSA, the issue of MRSA contaminated meat is still relevant.
Because the authorities have apparently failed to find any MRSA in a few barn dust samples reluctantly taken when ordered by the EU, that is used to support claims that British livestock is free of MRSA?
We need a few more lawyers taking notice of just what has been covered up in Britain for the last decade.
BSE should have been the wake-up call, let alone Circovirus, Classical Swine Fever and Foot and Mouth outbreaks in the last decade. There were, and are, others too.
Animals, just like people, do get ill, but not on this scale and with so much secrecy.
We need reform now and if it has to be sued and prosecuted into Britain's corrupt vets, so be it.

Commenting on an outbreak in the USA:
...It appears that MRSA-contaminated food was the vehicle in this outbreak affecting low-risk persons within the community, and that this food was likely contaminated by a healthy carrier whose only apparent exposure were visits to a possibly infected relative in a nursing home. This outbreak could be a health-care-associated infection that spread to the community. The outbreak strain of MRSA, however, was resistant only to penicillin and oxacillin and was sensitive to all other antibiotics tested. A strain originating in a health-care facility more likely would have been a multidrug resistant organism...

High prevalence of porcine circovirus viremia in newborn piglets in five clinically normal swine breeding herds in North America.
Department of Veterinary Diagnostic and Production Animal Medicine, College of Veterinary Medicine, Iowa State University, Ames, IA 50011, USA.
Porcine circovirus type 2 (PCV2) can be vertically transmitted resulting in fetal infection with or without clinical signs and lesions. The primary objective of this study was to assess the prevalence of intrauterine PCV2 infection in clinically normal newborn piglets in conventional pork production facilities. Five commercial breeding herds located in the U.S. and Mexico were included in the study...
... In conclusion, an unexpectedly high prevalence of PCV2 viremia was detected in healthy sows (serum and colostrum) and their pre-suckle piglets in the five breeding herds investigated and PCV2b was more prevalent than PCV2a. This information adds to the knowledge of PCV2 infection in breeding herds.

Last year authorities registered 39 Danes infected with MRSA CC 398th In the first 9 months of 2010, is the special pig bacterium according Statens Serum Institut registered in 55 Danes. Continuing spread of infection in the same pace the rest of the year, it will mean a doubling of infected people in 2010.
One of the leading researchers in staphylococci, a professor of microbiology and Dr. Hans Jørn Kolmos from Odense University Hospital, is surprised that neither the authorities or agriculture has done nothing to eliminate the problematic bacteria in the stables:
Hans Jørn Kolmos think the authorities should tackle the source of infection before the problem grows even bigger:

Minister for Food, Agriculture and Fisheries, Henrik Hoegh (V), is concerned that the bacterium spreads But he will not stop trade than MRSA-infected pigs or require screening here and now.
It is possible for infected people to get rid of the bacteria with very intense antibiotics and washes from skin and nose.

The Health Protection Agency is, not very convincingly, denying any link between Hepatitis E, pigs or pork.
Well, they would, wouldn’t they?
They are the people that were prosecuted by the Health and Safety Executive on bio-safety risks to their own staff after spilling E.Coli 0157 at one of their labs. see story
We can be sure the taxpayer pays the fine, and both sides' costs, when one government body prosecutes another.
If they can’t look after themselves, what hope for the rest of us.
They seem to be in direct contradiction with the man they worked with, and who has just received grants from other pig production areas, to continue his research.
The article, worth reading in full, reflects the difference in views.

Lack of knowledge is not an excuse
Professor Frank Moller Aarestrup from DTU Food does not understand that the Food Minister will await a trial that runs until next year before he will look at whether there should be something.
But one study will not be used to determine what exactly needs to be done, said Frank Moller Aarestrup.
- We will look at whether it makes a difference if we stop treating pigs with cephalosporins. But we have a strong suspicion that there are at least two other antibiotics involved namely zinc and tetrazyklin, so unless this study shows that cephalosporins cause 90 percent of the emergence of MRSA - and I think it is far from the case - then several attempts before we can finally say what is causing the spread. S So if Henrik Hoegh will wait until we have finished investigating, he comes to wait long, "he told The Engineer.
Therefore, the lack of knowledge is not an excuse for doing something now, says Frank Møller Aarestrup.

More information is slowly becoming available about the Hepatitis E investigation in Cornwall and Devon.
See Hepatitis E linked to British pigs and pork for previous report.
Research launched as rare virus is linked to three deaths in West
In addition to the deaths, it is thought 55 people have been struck down by the disease in Devon and Cornwall.
Medical experts are warning people to make sure they cook any pork products well and wash their hands thoroughly if they handle it raw...
...Dr Harry Dalton, consultant gastroenterologist at the Royal Cornwall Hospitals Trust and head of the Cornish team, said: "Not only had the patients not travelled abroad but they didn't fit the normal age range for the virus.
"In other parts of the world it usually affects the young. However, in the cases being seen in the UK, it is the middle-aged and elderly, particularly men."
It is believed that the main vectors of the disease are pigs and products derived from pigs...
...Patients with an existing liver condition are most at risk from Hepatitis E. The researchers will examine patients with liver problems who have been admitted to hospital with a worsening of their condition, to see whether the problems have been caused by exposure to Hepatitis E...

According to The Copenhagen Post today, the medical profession are urging the Danish government to take action to stop the spread of MRSA st398 in pigs and thence to humans.
They know that 13 per cent of pigs carry the strain and that 55 people this year have been infected.
The health minister, very concerned about the situation, needs more data.
Our report, from August last, details the quite extraordinary story of his efforts to get information from the veterinary profession: MRSA - Danish Minister Whistle-blows
The pig industry in Denmark is reported to have failed to take any action to date.
The widespread use of antibiotics on Danish pig farms is blamed for MRSA st398.

Staph strain ready to spread, doctors fear

Medical experts are urging the Health Ministry to take action against the spread of a highly contagious strain of bacteria now found in a resistant form in one out of eight pigs, reports public broadcaster DR.
According to a sample survey from DANMAP, the national programme for surveillance of antimicrobial resistance in bacteria, around 13 percent of pigs were found to be carrying the Methicillin-resistant Staphylococcus aureus (MRSA) CC 398 strain.
MSRA is resistant to antibiotics and can easily spread to humans.
... 55 people this year have already become infected with the bacteria...
...Some of these people are carriers who presently show no effects from the bacteria...
Henrik Høegh, the health minister, said he was concerned about the figures but added that the ministry needed more accurate diagnosis data before an effective action plan could be put into effect.
The pig farming industry has also yet to take action against the spread of the MRSA strain.
Dr Mads Koch Hansen, president of the Danish Medical Association, argued that the bacteria must be beaten back now before it spreads out of control...

... figures show that antibiotic use in broilers and finisher pigs has come down slightly over 2009, after a rapid increase in the previous years. Antibiotic use in sows and piglets, however, has increased after a small decrease in the years prior to that. In dairy cattle, antibiotic use decreased for the first time.
All in all, 2% less antibiotics were sold than in 2008.
The reduction is too small to achieve the Dutch authorities’ target to meet 50% reduction by 2011. Optimists refer to the best achieving farms using up to 90% less antibiotics.
For the whole of the EU, it was decided that per January 1, 2007, antibiotics were no longer allowed as growth promoters. ...

World MRSA Day on 2 October is a time for remembering the hundreds of thousands of people in the UK who have suffered gravely from MRSA in recent years. Although still high, hospital infection rates have now fallen thanks to a concerted effort to improve hygiene and antibiotic prescribing.
In contrast, MRSA in pigs and poultry has recently increased dramatically and tens of millions of animals around the world have become carriers of strains which can pass to humans. Scientists have said this rapid spread is due to the intensive conditions in which such animals are kept, the regular inclusion of antibiotics in their feed or water and the world trade in live animals.
In Europe, serious community-acquired human infections and some deaths have already been caused by farm-animal strains. The Government needs to pay urgent attention to the possibility that farm-animal MRSA may emerge as a major new reservoir of human infections in the UK. A first essential step is the introduction of a comprehensive testing programme for pigs and poultry at slaughter, imported meat and community-acquired strains in humans.

She asks if food could be a source of the dreaded C.Diff?
C. diff: Blame hospitals? Or food?By Maryn McKenna
October 6, 2010 |
People who are interested in infections that are transmitted in hospitals (umm, ghouls like me) have a special sick relish for Clostridium difficile, or in its short form, C. diff. C. diff lives in the intestines, part of a complex population of many bacteria — you did know there are more bacteria in your body than there are cells that belong to you, right? — but it roars out of control if those other bacteria are wiped out by a course of antibiotics, especially clindamycin. Removing the other bacteria clears out space for C. diff to reproduce in much greater numbers; the toxins it produces irritate the lining of the intestine, producing colitis, and triggering fever, cramps and diarrhea, and in the worst cases, sepsis. miscarriage and death.
C. diff colitis is one of the most common and serious hospital-acquired infections because — if you’re reading this over breakfast, you might want to stop eating now — severe diarrhea in a hospital patient who is confined to a bed and using a bedpan tends to get everywhere. Really, everywhere: bed linens and bedrails, floors and walls, stethoscopes, telephones, computer keyboards, and the hands of the healthcare personnel who operate those devices and then touch another patient.
C. diff persists so spectacularly because in the outside air, it forms a hard-shelled spore that protects its genetic material from assault — including from the alcohol in the hand gel that most healthcare workers use to clean their hands in between patients, and from the stomach acid of patients who swallow it. (See, I told you to stop eating.) Because of that, and because it’s such a devastating infection, hospitals toil incredibly hard at sanitizing to get rid of it,
C. diff colitis is a stubborn and ugly infection. ...
..Starting about 10 years ago, C. diff got dramatically more problematic: more virulent, more resistant to treatment, and more commonly occurring in people who would not have been expected to have it — often, healthy young people who had not been in hospitals, who seemed to be developing the illness in the outside world. Two CDC researchers said in 2008:
In the United States, the number of hospital discharges where (C. diff associated diarrhea, CDAD) was listed as any diagnosis doubled between 2000 and 2003... with a disproportionate increase for persons aged > 64 years. By 2003, regional reports of CDAD outbreaks from hospitals throughout the US and in Quebec, Canada emerged, describing severe disease associated with greater numbers of complications, including colectomies, treatment failures, and deaths. In 2004, the attributable mortality rate of nosocomial CDAD in Quebec hospitals was 6.9%, compared to 1.5% among Canadian hospitals in 1997. In the US, death certificate data suggest mortality rates due to CDAD increased from 5.7 per million population in 1999 to 23.7 per million in 2004. (Gould, Critical Care, 2008)
The reason for the surge has been understood to be the emergence of a new, hypervirulent strain of C. diff that produces up to 20 times more toxin than earlier ones. (C. diff nomenclature will make your brain hurt, but the strain is generally known as NAP1/027/BI, toxinotype III.) But increased virulence doesn’t explain the increased incidence, and the transmission patterns of the new strain have been murky...
An emerging line of inquiry suggests that the transmission patterns become much more clear if you look in a different place for the bacterium’s origin: not in hospitals, but in food.
C. diff has been identified in live pigs, cows and chickens. ...
