Antibiotics (Intensive Farms)

Caroline Lucas Excerpts

Wednesday 9th January 2013 Westminster Hall

[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.

[Caroline Lucas (Brighton, Pavilion) (Green)]

I congratulate the hon. Gentleman on securing this important debate. In the light of the very real health risks and the strong words from a former chief medical officer, as the hon. Gentleman has said, about the unnecessary use of antibiotics being nothing less than

“a death warrant for a future patient”,

does he agree that we need a legally binding timetable for the phased ending of all routine, prophylactic, non-therapeutic use of antibiotics in animals?

[Zac Goldsmith]

I do, and I will be coming to that point as well, but I absolutely agree with the hon. Lady’s intervention.

Clearly, we need to continue with efforts to reduce the inappropriate use of antibiotics by doctors, but the European Food Safety Authority was spot-on—I do not often say that—last year when it warned that

“it is…of high priority to decrease the total antimicrobial use in animal production in the EU.”

To date, the UK Government’s antibiotic resistance strategy, as I have said, has focused exclusively on over-prescribing by doctors, with zero mention of antibiotics in the livestock industry. Although they have spent money trying to understand why we are seeing a rise in bacterial infections, they are spending nothing, as far as I know, to understand the rise in resistance, which is clearly the issue of importance.

The Department of Health is currently developing its new cross-Government, five-year antimicrobial resistance strategy and action plan for 2013 to 2018, so I ask the Minister these questions today. Will she promise that it will give significant consideration to the use of antibiotics on farms and to the link between farm use and resistance? Will the Government work with the veterinary profession and the agricultural industry, as they have done in recent years with the medical profession? Does she agree that we need better data on antibiotic use, published by antibiotic family and by animal species, as is already done in France? If we do not know the type and quantity of antibiotics used and how they are used, there is very little chance of our being able to understand the emergence of resistance.

Furthermore, will the Minister lobby vigorously her ministerial colleagues at DEFRA to take urgent action to restrict the prophylactic use of antibiotics, to limit the prescription and use of antimicrobials for the herd treatment of animals to cases in which a vet has assessed that there is a clear clinical justification and to limit the use of critically important antibiotics to cases in which no other type of antimicrobials will be effective?

Will the Minister call on DEFRA to ban the use of fluoroquinolone antibiotics in poultry production to reduce the risk of antibiotic resistance in E. coli, campylobacter and other infections in humans? Incidentally, it is worth pointing out that campylobacter is the most common cause of food poisoning in the UK, affecting some 350,000 people a year, and poultry is the source of between 50% and 80% of those cases. A ban of that sort would bring the UK into line with the US, where the Food and Drug Administration stopped the use of those antibiotics in poultry in 2005, because of increasing resistance in campylobacter. Denmark, Finland and Australia also do not use fluoroquinolones in poultry. All those countries have lower levels of resistance in humans.

I mentioned Denmark, and it is worth taking a moment to consider the Danish situation. The latest Danish disease surveillance report showed that, although the presence of antibiotic-resistant bacteria in the country’s pig population had decreased since the tighter restrictions came into effect, including the banning of cephalosporins, the level of antibiotic-resistant bacteria in meats being imported into the country is higher than in its domestic meat. Nearly half the tested samples of chicken meat imported into Denmark in 2011 contained resistant bacteria. The Danish Government, quite rightly, have taken their concerns to Brussels, complaining that their national approach has been undermined by other EU states’ continued overuse of antibiotics.

Almost certainly, excessive antibiotic use on farms is linked to the intensive manner in which animals are kept. Improving animal health and welfare by limiting overcrowding and the worst excesses of factory farming must therefore become key components of the Government’s antibiotic resistance strategy. Disease prevention should be achieved through good hygiene, husbandry and housing, without recourse to the regular prophylactic use of antimicrobials—a point that has been made by two hon. Members. I recognise that factory farming interests have wielded enormous influence on Government policy for many years and that any move to restrict the use of antibiotics today will be fiercely resisted by them.

--- Later in debate ---

[Anna Soubry]

I am more than happy to do all those things. As my hon. Friend will appreciate, I am no expert in this field and would not pretend to be for one moment. I shall make a very important point: my briefing does not come from the Department of Health only; we work in collaboration with the Department for Environment, Food and Rural Affairs.

One important thing about this debate is that my hon. Friend rightly asked for a Minister from the Department of Health to respond, so I am not, as others might have thought, someone from DEFRA. Many people are concerned about whether how an animal is treated has an impact on them if they consume some or part of it. Although we might not always make too many friends in the farming industry, we are all responsible for ensuring that we know what we are putting into our bodies and feeding our families. We bear that responsibility, so we need good, informed advice. Many people, but often those with the financial means to do so, will not buy fresh meat unless they know its antecedents—that it has come from a good butcher and a good beast.

[Caroline Lucas]

I am grateful to the Minister for her openness to looking at more of the evidence that the hon. Member for Richmond Park presented. Having examined the greater body of evidence, will she also consider the need for legally binding measures as well as more information and awareness raising? The trends are going in the wrong direction, and we therefore need legally binding measures.

[Anna Soubry]

I am sort of grateful for that intervention; I fear that I could be in terrible danger of agreeing to do almost anything, and so would be able to do nothing else, because I would spend most of my time on this. I will do all that I can. It is very important. As individuals and parents, we all should be concerned, as many of us are, about what we eat and what we feed our children and loved ones. This is as much a public health issue as an animal welfare issue.

The Government have published a code of practice on the responsible use of medicines on the farm and a leaflet on antibiotics, which, like the above code, is on the Veterinary Medicines Directorate’s website. We just have to hope and pray that such things are read, but in my experience, responsible producers pay heed to all such advice. There are also regulations.

We continue to work actively with the farming industry to promote the responsible use of antibiotics in farmed animals, and industry organisations have also developed guidance. Furthermore, I am pleased to say that the Veterinary Medicines Regulations 2011 will be changed this year to prohibit the advertising of antibiotic products to professional keepers of animals. In addition, as my hon. Friend the Member for Richmond Park mentioned, from January 2012, the British Poultry Council introduced a voluntary ban on the use of certain critically important antibiotics in chick production, which should be welcomed.

Veterinary use of antibiotics is also being addressed at a European level. It forms a significant component of both the 2011 EU action plan against the rising threats from antimicrobial resistance and the 2012 EU Council conclusions. The EU legislation on veterinary medicines is currently under revision, and the UK, with other member states and the Commission, is examining the available evidence to establish whether there is a need for additional controls on antibiotics used in animals. The Government will continue to press for measures to strengthen controls on antibiotics that are critically important for human health, to make it clear that they should be used for animals only when no effective alternatives exist.

The Veterinary Medicines Directorate at DEFRA closely monitors the use of veterinary medicines in the UK. It analyses samples from food producing animals and their products for residues of veterinary medicines and environmental contaminants. There is no conclusive scientific evidence that food-producing animals form a reservoir of infection in the UK. Food is not considered a major source of infections resistant to antibiotics. Any bacteria associated with food or the environment can be reduced by thorough washing and cooking.

As I mentioned, the scientific consensus is that veterinary use of antibiotics is not a significant driver for human multiresistant infections. However, we are keen to see greater improvements in prescribing in all sectors and are actively working to encourage that. A wide programme of work to tackle antimicrobial resistance has been under way across the UK in the human and animal health sectors for several years. Although much has been achieved, I fully acknowledge that there are a number of areas that require attention and more radical thinking, if we are to have an even greater impact. I am confident that the new UK strategy will move us forward in that respect.

I undertake to write to any hon. Member who raised a question in the debate. Again, I congratulate my hon. Friend and assure him that I will answer all his questions. It now seems that I will read a great many documents and other evidence, but it is important work. If I feel that there is any need to make any changes, I will make them.
