Good Afternoon List Friends,
Today's posting from AnimalNet, the U of Guelph's email clipping
service, contained a release from Health Canada covering the "Canadian
Integrated Program for Antimicrobial Resistance Surveillance (CIPARS)
report"
The full (90 page) report in pdf format is available at:

ra/pdf/cipars-picra-2002_e.pdf
I was especially interested in the results of the abattoir survey of
cattle. The summary reported:
CATTLE
"Results from the first year of Abattoir Surveillance showed that 69% of
E. coli isolated from bovine
cecal samples were susceptible to all antimicrobials tested. All
isolates were susceptible to
antimicrobials of greatest human health importance (ceftiofur,
ceftriaxone, ciprofloxacin). With
the exception of tetracycline (27%), resistance to the other
antimicrobials tested was null or below
12%."
"Beef Cattle - Salmonella Isolates (Abattoir Surveillance n=1 isolate)
Only one Salmonella isolate was recovered from beef cattle through the
Abattoir Surveillance. This isolate was S. London and it was resistant
to tetracycline only.
They did not report the incidence of resistance in meat samples but in
the report on swine they noted that cecal samples carried much more
antibiotic resistant bacteria than meat samples:
SWINE
"55% of Salmonella isolated from porcine cecal samples were susceptible
to all antimicrobials tested." but that, "Seventy percent of all meat
(pork) isolates obtained through Passive Surveillance were susceptible
to all antimicrobials tested."
Thought this might be of interest to many of you in the livestock
business.
