(CIDRAP News) – A recent analysis of ground pork in grocery stores in five states showed that 4% of the samples contained enterococci with high-level resistance to gentamicin, an antibiotic used to treat enterococcal infections in humans. In addition, most Enterococcus faecium isolates were resistant to quinupristin-dalfopristin (Synercid), a streptogramin antibiotic used to treat infections caused by vancomycin-resistant E faecium.

(CIDRAP News) – Nearly a year and a half after the Food and Drug Administration (FDA) first proposed to stop the use of enrofloxacin (Baytril, a fluoroquinolone antibiotic) in poultry because of safety concerns, the agency says it plans to hold a public hearing on the proposal. The date of the hearing will be set at a prehearing conference on April 8.

A ruling by the Food and Drug Administration on whether to stop the use of enrofloxacin in poultry because of concern about antimicrobial resistance is more than a year away, according to a hearing schedule laid out by an FDA official.

In a Danish study, patients who had infections with a common drug-resistant type of Salmonella enterica were more than twice as likely to die within 2 years as patients infected with drug-susceptible variants of the same strain.

The most common cause of foodborne Salmonella infections grew increasingly resistant to the quinolone nalidixic acid between 1995 and 2000, according to a study from Denmark.

July 2, 2002 (CIDRAP News) – A recent series of 47 cases of salmonellosis in five states has linked an increasingly common multidrug-resistant strain of Salmonella enterica serotype Newport with ground beef, according to the Centers for Disease Control and Prevention (CDC).

(CIDRAP News) – The Food and Drug Administration (FDA) has released a guide to help the drug industry assess the risk that antimicrobial drugs intended for use in food animals will spawn resistant bacteria that could ultimately harm human health.

(CIDRAP News) – A study of antibiotic-resistant Campylobacter levels on retail chicken products suggests that the pathogen lingers in chickens long after antibiotic use among the birds is stopped.

(CIDRAP News) – A new report says oseltamivir-resistant forms of H5N1 avian influenza virus were found in two Vietnamese girls who died of the infection, raising doubts about the antiviral drug that many countries are counting on to help protect them from a potential flu pandemic.
