Super bug bacteria in meat and poultry, study says - SmartPlanet

Meat and poultry inspectors usually look for many types of multi-drug-resistant bacteria, but staph is often times overlooked. The bacteria can cause skin infections and can lead to more serious illnesses such as pneumonia and sepsis.

Here’s a summary of what the study, published in the journal Clinical Infectious Diseases, found:

• half of the meat sold in grocery stores are contaminated with S. aureus
• one in four samples were resistant to at least three classes of antibiotics
• methicillin-resistant staph was found in three of the samples
• the staph are resistant to up to nine different antibioitics, making it hard to treat

However, The New York Times reports that “federal health officials estimate that staph accounts for less than 3 percent of all food-borne illnesses. In a statement Friday, the American Meat Institute said the study was misleading.” Businessweek reports staph infections occur only three percent of the time and are not nearly as common as other foodborne illnesses like salmonella and E. coli.

Multidrug-Resistant Staphylococcus aureus in US Meat and Poultry

Abstract

We characterized the prevalence, antibiotic susceptibility profiles, and genotypes of Staphylococcus aureus among US meat and poultry samples (n = 136). S. aureus contaminated 47% of samples, and multidrug resistance was common among isolates (52%). S. aureus genotypes and resistance profiles differed significantly among sample types, suggesting food animal–specific contamination.

Antimicrobials are used extensively in food animal production, where they are often applied subtherapeutically for growth promotion and routine disease prevention [1]. Surveys conducted by the National Antimicrobial Resistance Monitoring System (NARMS) indicate that retail meat and poultry products are frequently contaminated with multidrug-resistant Campylobacter species, Salmonella species, Enterococcus species, and Escherichia coli [2]; but little is known about the prevalence of other antibiotic-resistant pathogens in the US food supply.

MRSA Protocols- Are They Being Used In Practice? | Registered Nurse Blog

Posted: April 2nd, 2011

In Advance For NPs and PAs, a March 9, 2011 article was featured on the following study of protocols used by health care providers to treat MRSA infections. I was surprised to see that some providers were still using Keflex to treat these infections. Some providers still were not sending cultures on these infections. How can we adequately treat an infection without knowing what will actually kill the bacteria? My impression of the following information is that the protocol that I do is somehow a new treatment regimen. I have been doing incision and drainage with appropriate culturing with first line Septra for the last 3 plus years. I also use mupricion ointment to nares twice daily and Hibaclens during the regimen if they have had more than one outbreak within a 6 month period.

Taking Aim at MRSA
Protocol use by an NP-PA team
Anita D. Barnes is a family nurse practitioner who is an assistant professor of nursing at Stephen F. Austin State University in Nacogdoches, Texas.
A 2009 study reported a variety of approaches used by ED physicians to treat CA-MRSA SSTIs.6 The study surveyed 225 ED physicians nationwide: 56% reported always sending cultures for testing and 19% said they never did so. The physicians prescribed trimethoprim-sulfamethoxazole (TMP-SMX) 60% of the time, either alone or in combination with another antibiotic. Nineteen percent treated patients with cephalexin alone, and 13% prescribed cephalexin in combination with another antibiotic. Cephalexin is not recommended in the CDC protocol.

What are you doing as providers to treat MRSA infections? Do you find the information alarming that some providers are still not culturing infections?
