Where are we at with antimicrobial resistance?

Vet Advice with Dr. Ron Clarke

By
Antimicrobial resistance (AMR), often incorrectly labelled antibiotic resistance, has been the subject of immeasurable media attention through the past three decades. It’s a relentless rabble of potential health threats, what and who is to blame, and where do we go from here. AMR has spawned at least two generations, maybe three, of academic scrutiny, dissection, […] Read more

Cutting time on tylosin

Researchers looked at whether feeding tylosin for a shorter period affects antimicrobial resistance, along with liver abscesses, health and growth of feedlot cattle

By ,
Liver abscesses in cattle have been extensively studied for the last 70 years. Yet condemned or discounted livers due to abscesses still cost the Canadian beef industry over $60 million per year. Tylosin, a member of the macrolide family of antimicrobials, is widely used in beef cattle and is administered through the diet to reduce […] Read more
Canada’s beef industry has worked long and hard to help get an integrated on-farm surveillance program for antimicrobial resistance underway in the feedlot sector.

On-farm antimicrobial surveillance moves a step closer

Research on the Record with Reynold Bergen

By
As long as cattle continue to get sick, cattle producers will need anti­microb­ials to help them recover. At the same time, it’s common to hear activists, regulators, consumers and/or retailers call for livestock producers to stop using antimicrobials altogether, reduce anti­microbial use, or demonstrate that antimicrobials are being used responsibly. Solid, reliable data demonstrating our […] Read more
Over a two-year period, a research team collected samples from feedlots, agricultural soils, wetlands, streams, municipal sewage, packing plants, retail meats and human patients.

Does antibiotic resistance move through the environment?

Research on the Record with Reynold Bergen

By
Recent columns have talked about antibiotic use in Canadian cow-calf and feedlot operations. Contrary to common misperceptions, antibiotic-resistant bacteria are very unlikely to transfer from cattle to beef, evade food safety interventions in the processing plant, survive cooking, and cause an antibiotic-resistant infection in a person. But can antibiotic-resistant bacteria be transmitted from cattle, through […] Read more

Are you ready for December 1, 2018?

Nutrition with John McKinnon

By
December 1, 2018, is an important date that all Canadian beef producers should be aware of. It marks the end of the phase-in period, after which Health Canada will enforce new regulations as to how medically important antimicrobials (MIA) that were previously sold over the counter without veterinary prescription are regulated, dispensed and used within […] Read more

Antibiotic use in Canadian feedlots

Research on the Record with Reynold Bergen

By
September’s column summarized a Beef Cluster project that evaluated antibiotic use in western Canadian cow-calf operations. Nearly all cow-calf farms used antibiotics, but very few animals were treated, and most of the antibiotics used were not related to the antibiotics most commonly used in humans. But when it comes to antibiotic use in the beef […] Read more
Antimicrobial resistance should not be looked at as a threat, but rather an opportunity to reach the next level of quality and sustainable livestock production.

Change is upon us

Animal Health with Dr. Ron Clarke

By
Regardless of a person’s perspective on changes coming on antibiotic use in the livestock industry, one thing clear: change is not just on the way — it’s arrived on the doorstep. If not ready, it’s time to get ready. Gaps identified in the use and sale of antimicrobials in animals are nearly two decades old […] Read more

EU backs plan to tackle antimicrobial resistance

By
Brussels | Reuters — EU member states backed a plan on Wednesday to combat antimicrobial resistance, an increasing global health issue, that would reduce the use of antibiotics in the food chain and limit certain drugs to humans. Antimicrobial resistance threatens the effectiveness of medicines such as antibiotics to treat infections in humans, as bacteria […] Read more

Comment: The other shoe is about to drop on livestock drugs

Increased fees for veterinary product registrations is likely to result in higher prices

In case you missed it April 1 was the day the revised Compendium of Medicating Ingredient Brochures or CMIB was posted online by the Canadian Food Inspection Agency to conform to Health Canada’s plan to combat antibiotic resistance in these vital drugs. The release of the revised CMIB starts the clock on bringing all antimicrobials […] Read more

Vet Advice: New regs to preserve old and new drugs

By
I’m often asked why even older antimicrobials are still considered medically important to human medicine. The premise, right or wrong, is to preserve antibiotic effectiveness by reducing the risk of antimicrobial resistance attributed to wholesale use in animal agriculture. While debate still rages over the impact new legislation will have on preserving antimicrobial effectiveness in […] Read more
