Trends in the Incidence of Methicillin‐Resistant Staphylococcus aureus Infection in Children’s Hospitals in the United States

Just this week, researchers reported that the incidence of MRSA infections among children admitted to pediatric hospitals in the United States more than tripled between 2002 and 2007. Researchers at the Children’s Hospital of Philadelphia and the University of Pennsylvania found cases of MRSA jumped from 6.7 per 1,000 admissions in 2002 to 21.1 cases per 1,000 admissions in 2007, according to a study released online Monday in the journal Clinical Infectious Diseases.

Another study, this one published in the U.S. journal Clinical Infectious Diseases in 2006, found that workers in meat-processing plants have a greater likelihood of being infected by some version of the H1N1 flu virus than the general population (the odds of pig farmers getting the disease are significantly greater again).

Every year, an estimated 915,000 people 65 and older get pneumonia, and 40 percent of them end up in hospitals, according to a 2004 paper in the journal Clinical Infectious Diseases. Pneumonia often kills older people, said Richard Stefanacci, a geriatrician at the University of the Sciences in Philadelphia.

FOOD SAFETY INVITED ARTICLE

The Growing Threat of Foodborne Bacterial Enteropathogens of Animal Origin

Campylobacter and Salmonella species and Shiga toxin–producing Escherichia coli (STEC; the majority of which are type O157:H7) efficiently enter the human food chain from infected or colonized animals. Poultry contamination with Campylobacter and/or Salmonella species and produce contamination with STEC have become major public health challenges. The global food supply, which allows us to purchase desired items throughout the year, a growing interest in consuming fresh vegetables and fruits, and an increasing number of persons who consume foods at restaurants all assure that the health threats associated with these pathogens will continue. Antibiotic use by humans and food animals selects for the development of resistance among Campylobacter and Salmonella strains, promoting invasive forms of infection and complicating therapy of illness. A comprehensive public health approach is needed that focuses on disease surveillance and infection control in the food industry continuum, from harvesting and processing, to distribution, to later preparation in public eating establishments and in homes. Good Agricultural Practices, including the Hazard Analysis and Critical Control Point Program and validation of critical infection‐control points at all stages of the food industry cycle, coupled with other food safety interventions, including irradiation for certain higher‐risk foods, should help us improve the quality of food with regard to microbials and reduce human disease.
