I have been slow at picking this ball up, but the book chapter that I coauthored with Stefanie Hess is now available online (and has been for almost a month). It is part of the book Antibiotic Drug Resistance, edited by José-Luis Capelo-Martínez and Gilberto Igrejas and was available in print on September 9th.

Our chapter deals with sources of resistant bacteria to the environment, and in particular the roles of sewage, wastewater and agriculture in resistance dissemination. Furthermore, the chapter discusses de novo selection of resistance and defines relevant risk scenarios. Finally, we outline the different management options available and discuss their feasibility.

The chapter boils down to that the available strategies for limiting antibiotic resistance dissemination and selection in the environment are overall quite clear. Larger problems that remain to be solved are how to prioritize between different strategies, which technologies that would provide the largest benefits and to achieve the political willingness to pursue these strategies. We note that several of the most efficient resistance prevention options involve high costs, investments in technology and infrastructure in other countries or proposals that are likely to be rather unpopular with the general public. For example, investing in sewage treatment and water infrastructure in low-income countries would likely be among the most effective means to reduce releases of resistant bacteria into the environment and reduced meat consumption would contribute to lower the use of antibiotics in animal husbandry, but neither is a very popular proposal for tax payers in high-income countries.

I have not yet read the entire book myself, but the table of content shows a very wide-reaching and comprehensive picture of the antibiotic resistance field, with a range of prominent authors. The editors have made a good job collecting this many interesting book chapters in the same volume!

In two weeks time, on the 15th of June, I will participate in a seminar organised by Landstingens nätverk för läkemedel och miljö (the Swedish county council network for pharmaceuticals and environment; the seminar will be held in Swedish) in Stockholm. I will give a talk on our proposed emission limits for antibiotics published last year (the paper is available here), but there will also be talks on wastewater treatment, sustainable pharmaceutical usage and environmental standards for pharmaceuticals. The full program can be found here, and you may register here until June 9. The seminar is free of charge.

And if you are interested in this, I can also recommend the webinar given by Healthcare Without Harm next week (on June 8), which will deal with sustainable procurement as a means to deal with pharmaceutical pollution in the environment. I will at least tune in to hear how the discussion goes here.

UPDATE: This post has been updated to reflect a valid comment that I messed up in the original post. Specific use of antibiotics as feed additives has been forbidden for years in the EU. The petition was about cutting the prophylactic use of antibiotics in animals, but that was very unclear from the original post. I thank my readers for pointing this unclarity out.

I’m going to do something unusual and ask you to sign a petition targeted at European Union ministers to support new EU laws to drastically cut the prophylactic use of antibiotics in agriculture as growth promoters. The problem is that if ministers don’t feel the public pressure to act, the laws may be delayed or not be implemented. Examples from Denmark, Sweden, Norway and the Netherlands show that it is possible to produce meat with little or no antibiotics, but since bacteria can travel across borders (1), we need to bring the rest of the world onboard, and the EU is good first step. Therefore I ask you to sign the Avaaz petition here.
