Abscessed livers with A+ scores such as this one are condemned.

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

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

Ottawa looks to speed up emergency access to livestock drugs

Livestock drugs not currently available in Canada could become easier to access in emergencies, if proposals for amended federal drug regulations get on the books. Health Canada, proposing to streamline the processes for emergency access to drugs for livestock as well as people and pets, on Friday announced a public comment period on its proposals, […] Read more


New drug regulations require adjustment

Vet Advice with Dr. Ron Clarke

No issue over the past 15 years occupied more space in agriculture, veterinary or public health-related press than antimicrobial resistance (AMR). No single topic appears more often on conference and seminar agendas than topics addressing the use, abuse and prudent use of antimicrobials in humans and animals. Petitions, a plethora of committees of every description, […] Read more

Ending antimicrobial resistance with a SNAPP

Straight from the Hip with Brenda Schoepp

The United Nations has declared antimicrobial resistance a global fundamental threat. It is interesting that the emergence of antimicrobial resistance (AMR) has really taken a short time in our human history to become a near epidemic. Today antibiotic use is considered suboptimal and in many cases unnecessary because of the widespread use without the confirmation […] Read more


Regulatory changes would limit farmers’ vet drug imports

Proposed Health Canada changes will affect how antimicrobials are imported into Canada

For John Prescott, a move to end farmers’ right to import certain veterinary drugs marks a significant turning point in the fight against antimicrobial resistance in Canada. The Public Health Agency announced last year that Health Canada’s Veterinary Drugs Directorate would introduce new regulations requiring veterinary oversight of antibiotics used in food animals, such as […] Read more

The AMR Dilemma: Part 2 – The impact

Finding the missing pieces to the puzzle of antimicrobial resistance

Although accurate statistics are difficult to tabulate, over two million people in North America become infected with bacteria resistant to antibiotics annually. At least 23,000 people die as a direct result of these infections. Virtually, all significant bacterial infections in the world are becoming resistant to the antibiotic treatment of choice. Health authorities in North […] Read more


The AMR dilemma: Part 1

Searching for ways to move forward on antimicrobial resistance

No issue in the past 15 years logged more space in agriculture, veterinary or public health-related press than antimicrobial resistance (AMR). No single topic appears more often on conference and seminar agendas than the one addressing prudent use and abuse of antimicrobials in humans and animals. Despite the attention AMR has received, we have not […] Read more

Conjugation, and what it means for antimicrobial resistance in livestock

The federal government’s CIPARS program studies E. coli in healthy cattle entering packing plants and in retail ground beef. Its surveillance shows that resistance to antimicrobials of the highest importance in human health continues to be very rare in these samples, and multi-drug-resistant bacteria are even less common. The risk of consumers being exposed to […] Read more

Tracking resistance to drugs in cattle bugs

It’s on the increase

The warning sign went up as results came in from two Alberta projects exploring the susceptibility of bacteria involved in bovine respiratory disease (BRD) to available antimicrobials. Alberta Beef Producers (ABP) administered the year-long project testing for antimicrobial resistance in feedlot cattle in order to develop an in-province screening tool. The project involved several industry, […] Read more

Study to portray state of cow-calf sector

A team of researchers at the University of Saskatchewan and University of Calgary have received a $1.06-million grant from the Beef Cattle Research Council (BCRC) to conduct a five-year longitudinal study of the western Canadian cow-calf industry. The study aims to measure reproductive health, animal welfare, disease prevalence, antimicrobial use and other issues affecting Canada’s […] Read more
