Fate of antibiotic resistant bacteria and genes in manure storage

Manure storage and its application on cropland may contribute a form of environmental contamination: antimicrobial-resistant bacteria. These bacteria in manure are perceived to cause diseases in humans through environmental contamination. However, a recent study at the University of Nebraska-Lincoln feedlots near Mead, Nebraska concluded that long-term manure storage as static stockpiles has the advantage of inactivating antimicrobial-resistant bacteria, and it has the potential to reduce antimicrobial resistance genes.…

How do you like your steak?

People worry, and I am no exception. I spend more time than I would like to admit on social media, and I have seen some things, disturbing things, things that cannot be unseen. Turns out there is a lot out there to be worried about; so how do I know I am worried the right amount and not too much? For example, I know that antimicrobial resistance (AMR) is a serious and growing health problem, but what does that mean for me?…

Antimicrobial Resistance Resource Library

Antimicrobial-resistant (AMR) infections are a serious threat to global public health. Each year AMR accounts for roughly 700,000 deaths worldwide. While AMR-related research is ongoing, conveying research-based knowledge about AMR mechanisms, risks, and opportunities to improve outcomes to the general public, agricultural producers, food safety experts, educators, and consumers is imperative.…

Are there alternatives to antibiotics?

A brief summary of the manuscript, Alternatives to Antibiotics: Why and How (Allen, 2017), a review of current and potential alternatives to antibiotics for use in human or veterinary medicine.

Key Takeaways:

  • Every time antibiotics are used, impacted bacteria adapt to survive. Bacteria that are not killed by the antibiotic pass on their new survival traits to later generations of bacteria, which limit the effect of the antibiotic the next time it is used.

Antimicrobial Resistance is Native to the Environment

Germs are everywhere, some resistant to medical treatment

When I was a kid, I remember being called inside for lunch on a summer day and hearing, “Wash your hands! You’ve been playing in the dirt!” Of course, we all grew up knowing that dirty hands can spread germs. But, I didn’t know until I was much older that the same soil that made my hands dirty was also the source of some pretty amazing medicines.…

Managing Manure to Mitigate Antibiotic Resistance

This webinar highlights some of the work being done to identify effective practices for reducing concentrations of resistant bacteria and resistance genes at critical control points in beef feedlot and dairy manure management systems. This presentation was originally broadcast on November 15, 2019.…

Reduction and fate of manure pathogens and antimicrobial resistance

Antimicrobial resistance is a complex issue as it is comprised of not only pathogenic bacteria, but also non-pathogens which share genes within complex environmental systems, such as agricultural fields. This webinar describes potential measures to reduce pathogen and antimicrobial resistance in manure as well as potential fate and transport of manure pathogens and antimicrobial resistance following land application of manure.…
