#manure_lagoon

C’est marrant au premier regard mais trés inquiétant quand on continue la lecture :

The best short-term solution farmers have come up is antibiotics. Rumensin 90, an antibiotic normally used to prevent bloating in cattle, has been repurposed to prevent gas in pig manure pits. It works, though no one knows why. Scientists have hypothesized that shifts in the microbial community—either from DDGS feeding or from another cause—may have a role in foaming manure as well.

All the unknowns around exploding hog manure foam suggest being careful about unintended consequences. Farming accounts for 80% of all antibiotics sold in the United States, and widespread use of antibiotics in farm animals contributes to the development of deadly antibiotic-resistant infections in people.

oui c’est très sérieux : les #résistances, essentiellement dues à l’usage des antibio en élevage animal [et pas en santé animale !], sont en train de réduire nos capacités à soigner les maladies chez l’humain

Rappel : l’une des hypothèses sur l’origine de la grippe porcine/grippe mexicaine/grippe H1N1 2009 est le lien avec le plus grand site de production de porcs de #Smithfield à La Gloria au Mexique.

Sur le lien entre la résistance aux antibiotiques chez l’animal chez l’homme, par exemple cette étude de l’Université Purdue sur l’interdiction des antibiotiques dans l’alimentation animale au Danemark en 2009 (étude de décembre 2010).

Denmark banned AGPs because officials wanted to reduce antimicrobial resistance in bacteria from food animals. In this, the ban was largely successful, because resistance in various types of bacteria decreased from 2000 to 2008. Likewise, overall use of antimicrobials in food animal production decreased. The larger question is if this lowered antimicrobial resistance in bacteria from pigs or chickens translates into reduced antimicrobial resistance in bacteria from humans. This does not seem to be the case.
While resistance in bacteria from livestock decreased, resistance in bacteria from humans remained the same or increased in almost every type of bacteria tested. In many cases, the increase in resistance to specific drugs was likely caused by increased use of that drug in human medicine (e.g., fluoroquinolones, cephalosporins).
Therefore, it appears that antimicrobial resistance patterns in bacteria from animals and humans are not closely related. That is, antimicrobial resistance patterns in livestock result from antimicrobial use patterns in veterinary medicine and antimicrobial resistance patterns in humans result from antimicrobial use patterns in human medicine. This suggests that changes in antimicrobial resistance patterns in bacteria isolated from livestock have limited influence on antimicrobial resistance patterns in bacteria isolated from humans.

D’une autre côté, Purdue a un centre d’expertise CAFO car l’état d’Indiana est l’un de ceux où l’élevage industriel est en progression…
Le centre de ressources se présente ainsi (avec questions implicites sur le financement…)

Indiana is experiencing significant growth in the animal agriculture sector, much of it in the form of concentrated animal feeding operations (CAFOs), and many Indiana citizens are concerned about the impact that these new farms might have on their communities.

Purdue University has brought together a wide range of experts to address and research different concerns surrounding CAFOs. Our goal is to afford consumers, producers, and community leaders the ability to make well-informed decisions regarding issues that may coincide with the expansion of animal agriculture in Indiana.
