Recent bison deaths in North Battleford caused by anthrax

Disease has a highly rapid onset in cattle resulting in sudden death

With high temperatures and drought, cattle and bison are at a higher risk of anthrax. Two bison deaths northwest of North Battleford, Saskatchewan have recently been confirmed as caused by anthrax, and seven others are suspected. Producers are encouraged to keep a watchful eye and to refresh their memories on what to do when anthrax […] Read more

There is no evidence that ionophore use in livestock increases resistance to other antibiotics that are important in cattle or human medicine.

Are ionophore antibiotics a risk for antimicrobial resistance?

Last month’s column talked about Health Canada’s initiative to phase out growth promotion claims for medically important antibiotics by December 2016. This will impact three antibiotics (tetracycline, sulfamethazine and neomycin) that have growth promotion claims in beef cattle in Canada. It will not affect ionophore antibiotics like Rumensin, Bovatec, or Posistac. Ionophores are used widely […] Read more

Comment: Get ready for antimicrobial resistance

The feds have a plan, but there's no quick fixes to AMR

AMR or antimicrobial resistance; the term certainly isn’t new, but it’s likely you will be hearing more about it now that Ottawa has released its Federal Action Plan on Antimicrobial Resistance and Use. Canada is also working toward endorsing a Global Action Plan by the World Health Assembly. In essence the federal government has started […] Read more

Hot water treatment of beef trim

Combating bacteria would be simple if they stayed on the surface of beef. In that case, nearly any spray or wash could contact and kill the bacteria or wash them off. But beef isn’t smooth. Shallow cuts and cracks crisscrossing the meat surface can hide and protect bacteria. Killing these hidden bacteria is not simple. […] Read more

Scientists create ‘genetic firewall’ for new forms of life

New York | Reuters — A year after creating organisms that use a genetic code different from every other living thing, two teams of scientists have achieved another “synthetic biology” milestone: They created bacteria that cannot survive without a specific manmade chemical, potentially overcoming a major obstacle to wider use of genetically modified organisms (GMOs).

Talk, tweet and shout about antibiotics for food animals

We've sat back long enough

We’ve sat back long enough

Sickness happens. When animals get sick they need treatment every bit as much as people. Retaining access to effective antibiotics for food animals is important for animal welfare and food safety because raising healthy animals means healthful, safe food. This is an important message consumers need to hear from producers in the discussion on antibiotic […] Read more

It's in the stars... antimicrobial resistance tops list of concerns for this century

Friday, June 13 and a full moon. An astrological phenomenon made for witches and those rummaging for bad omens; an event not to be repeated until 2049 — a cycle of 35 years. It’s an interesting span of time that stirs the imagination of those, like myself, who spend most days wondering about the future. […] Read more

WHO report declares antimicrobial resistance 'a global security threat'

In May the World Health Organization (WHO) issued its global report on antibiotic resistance stating that antimicrobial resistance (AMR) “is now a global security threat.” And although the report acknowledges a more disciplined approach to the use of human antibiotic therapy it had a strong message for the food animal industry as well. The situation […] Read more
