Antibiotics (Intensive Farms)

Jim Shannon Excerpts

Wednesday 9th January 2013 Westminster Hall

[Zac Goldsmith]

I thank the right hon. Gentleman for his intervention. I suspect that that is part of the problem, but as I will come to later, I think it is also the case that the agribusiness sector in this country has had a disproportionate impact on policy. That is a point that I hope to impress during the debate.

As I was saying, there has been a near clean sweep of Ministers at both Departments, so this debate provides an opportunity to clarify Government policy. The Government are right to insist on better infection control in hospitals and changes in the way that antibiotics are prescribed by doctors. However, other than the brief answer that I quoted from the former Secretary of State, there has been virtually nothing from the Government that could in any way encourage vets and farmers to be similarly prudent. Not surprisingly, therefore, there has been little progress; on the contrary, analysis by the Soil Association of the Government’s statistics indicates that the overall use of antibiotics per animal on UK farms increased by 18% between 2000 and 2010, while the farm use of third and fourth-generation cephalosporins—drugs described by the Health Protection Agency as hospital workhorses—increased by over 500%.

Furthermore, recently published data from the Veterinary Medicines Directorate show that sales of fluoroquinolone antibiotics for use in veterinary medicine over the past two years have been 70% higher than they were in 2000. It is worth noting that when fluoroquinolones were first licensed for use in poultry in the UK in 1993, there was no registered antibiotic-resistant campylobacter in people who had not been treated with the antibiotics, but by 2007, almost half—46%—the campylobacter food poisoning cases caused by the most common strain were resistant. It is worth noting also that in 2008, the European Food Safety Authority said:

“A major source of human exposure to fluoroquinolone resistance via food appears to be poultry”.

Clearly, antimicrobials should be used to treat sick animals, and I do not think anyone would argue against that.

I congratulate the hon. Gentleman on securing the debate. Does he feel that the use by the farming sectors—whether pig, poultry or beef—of antibiotics is unnecessary, because there is a blanket use, rather than reacting to disease? Does he feel that that has a direct impact on us as human beings? Many people come to me and say that the antibiotics are not working, and they are getting three doses from the doctor. Is that feeding off what is happening?

[Zac Goldsmith]

Again, I absolutely agree with the hon. Gentleman’s point, and I thank him for making it. I will come to that in more detail shortly.

There is no argument against treating sick animals with antimicrobials but, surely, not the most modern and medically important ones, especially when other antibiotics, which are not as critically important in human medicine, are available. I recognise that this topic does not lend itself easily to tabloid news, but there is a real, worrying chance that that could change. By overusing antibiotics, we risk ruining for future generations one of the great discoveries of our species. In short, we risk entering the post-antibiotics age.

My hon. Friend the Minister will know that some antibiotics have already been lost to resistance: for example, penicillin for staphylococcal wound infections, ampicillin for infections of the urinary tract and ciprofloxacin for treating gonorrhoea. Many more are under threat, and new antibiotics are increasingly hard to find and license. We are now using our reserve antibiotics, and worryingly, seeing the spread of resistance to them as well. For example, rises in resistance, such as those seen for E. coli, force doctors to use carbapenems, which were previously the reserve antibiotics for use when other treatments had completely failed. However, we are now using carbapenems much more and seeing the spread of resistance to them as well.

University of Cambridge researchers revealed the first cases in UK livestock of a new strain of the multi-resistant superbug MRSA. It is called ST398, and it has become endemic in European and north American pig populations and has spread to poultry and cattle. It is significant because, unlike most strains of staphylococcus aureus found in farm animals, it is readily able to transfer to humans. If not checked, that is likely to lead to rising community-acquired MRSA, just at the time that hospital-acquired MRSA is falling, due to sterling efforts by health professionals.
