Although important declines in foodborne infections have occurred in FoodNet surveillance, additional efforts are needed to sustain and extend these declines to improve prevention of infections caused by Salmonella and other foodborne pathogens.
Foodborne illnesses present a substantial health burden in the United States. FoodNet conducts active surveillance for laboratory-confirmed illnesses caused by enteric pathogens transmitted commonly through food. This report describes preliminary surveillance data for 2005 and compares them with baseline data from 1996–1998. The 2005 data indicate declines in the incidence of infections caused by Campylobacter, Listeria, Salmonella, Shigella, Shiga-toxin producing Escherichia coli (STEC) O157, and Yersinia. However, most of those declines occurred before 2005 and are now reaching a plateau; Vibrio infections have not declined. Additionally, although the overall incidence of infections caused by Salmonella has decreased, of the five most common Salmonella serotypes, only Typhimurium has declined, with most of the decline occurring by 2001. These findings indicate that further efforts are needed to sustain and extend these declines and to improve prevention of foodborne illness.
Multisite Outbreak of Norovirus Associated with a Franchise Restaurant – Kent County, Michigan, May 2005
PRESS CONTACT: |
To prevent norovirus, food service workers should be educated on norovirus transmission and control.
This investigation led to the discovery that an asymptomatic food worker spread norovirus to at least 100 people at multiple sites throughout Kent County, Michigan. To prevent norovirus outbreaks, food service workers should be educated regarding norovirus transmission and control. In 2005, new guidelines for state health departments regarding norovirus containment were published by the Food and Drug Administration (FDA); guidelines for local health departments in Michigan were issued by the state’s Department of Community Health and Department of Agriculture. The new guidelines for Michigan recommend that food service workers with suspected norovirus not return to work until they are asymptomatic for 48–72 hours. Additionally, the Michigan guidelines offer recommendations for cleaning and disinfection of norovirus, advising the concentration of bleach required for cleaning porous and nonporous surfaces.
Survey of Lymphocytic Choriomeningitis Virus Diagnosis and Testing – Connecticut, 2005
PRESS CONTACT: |
Clinicians should be aware of how LCMV infection manifests in susceptible populations, including immunocompromised persons, and conduct testing whenever LCMV infection is possible and there is potential rodent exposure. LCMV is a rodent-borne virus that can cause serious central nervous system infection in otherwise well people, congenital birth defects in fetuses exposed in utero and life-threatening disease in immunocompromised persons such as organ transplant recipients. Since pet rodents or mouse infestations are the most common sources of exposure to LCMV, recognition of a single case and elimination of the source can prevent wider outbreaks. Clinicians need to be knowledgeable about risk factors for infection and sensitive to how LCMV infection manifests. In the absence of regular testing for LCMV in the pet industry, human surveillance should be considered as an alternative means of monitoring for LCMV disease in both human and pet rodent populations.
Botulism from Home-Preserved Bamboo Shoots – Nan Province, Thailand, March 2006
PRESS CONTACT: |
Botulism is a severe form of food poisoning and this outbreak highlights the need for continued education, inspection and quality assurance to prevent illness from improperly prepared foods.
In March 2006, a large outbreak of botulism occurred in Northern Thailand. Home-canned bamboo shoots were implicated as the contaminated food source. Rapid investigation and good international communication and collaboration were critical to the quick investigation and response, and to the delivery of life-saving anti-toxin. To date, no patients have died.
