SAO PAULO (Reuters) - Pork products sold at
retailers in Brazil contain antibiotic-resistant bacteria, according to
a study funded by animal rights group World Animal Protection (WAP),
providing potential evidence of overuse of the medicines in food
livestock.

The study, which also looked at pork in three other countries, was
conducted by the University of Săo Paulo on behalf of WAP in Brazil.
It examined 100 meat samples from outlets owned by Carrefour, GPA
and Walmart, WAP said.
"In all of the samples, the tests detected a generalized presence of
bacteria resistant to antibiotics," WPA noted in a report last week
describing the study's findings.
Researcher Terezinha Knobl told Reuters on Monday that the issue
related to super-resistant bacteria is global and addressing it is
one of five priorities of the World Health Organization.
Still, she noted consumers need not be alarmed as there is no
immediate risk of death or disease related to meat consumption.
"One of the aims of the study is advocating for a more rational use
of antibiotics in livestock production," Knobl said.
As antibiotics are overused both in people and to prevent disease in
livestock, the fear is that bacteria will develop resistance to all
available treatments for when they are truly needed.
"Beyond treating disease, the antibiotics are commonly used to avoid
illnesses caused by the handling of the animals and the high levels
of stress caused by the extreme conditions in which they are
confined," WAP said.

According to the BMC Veterinary Research journal, antimicrobial
resistance is a public health threat worldwide. There are at least
two million resistant infections and at least 23,000 related deaths
in the United States each year, its research showed.
The rise of resistant bacteria may lead to a clamp-down on overuse
of antimicrobial drugs in Brazil, the world's fourth largest pork
producer and exporter, and elsewhere.
U.S. livestock consumes 70 percent of all antibiotics, according to
a 2014 Britain-commissioned Review on Antimicrobial Resistance.
Earlier this month, McDonald’s Corp said it would take steps to curb
use of antibiotics in its global beef supply.
Brazil's unit of Carrefour said it is working with WAP to improve
animal well-being policies. GPA said it only sells meat products
inspected by the Agriculture Ministry. Walmart did not immediately
reply to a request for comment.
"There can be no pork production without antibiotics," said
Brazilian pig farmer Wilant Boogaard, arguing that vaccines and
antibiotics are needed to prevent and treat disease.
