Salmonella surveillance report ; no. 37, MAY 26, 1965
Details:
  • Description:
    For the Month of April, 1965 During April a total of 1,274 isolations of salmonellae from human sources were reported to the Salmonella Surveillance Unit for an average weekly total of 318. This represented a slight increase of 15 recoveries per week over March 1965 and a decrease of 57 isolations per week over April 1964. The trend observed in the first quarter of 1965 is continuing with total isolations running approximately 2 per cent fewer than the human recoveries during the same period last year. Outbreaks of infection due to Salmonella heidelberg continue to be a problem, primarily in the states west of the continental divide. A report is included in this issue of an outbreak of gastroenteritis due to S. heidelberg in Hawaii. At the time this issue goes to press, reports have been received of a common source outbreak due to j>. heidelberg in the State of Oregon. Preliminary information indicates that the source in this outbreak may be eggs and egg products contaminated with S. heidelberg. Previous outbreaks of S. heidelberg infection have been noted in the states of Washington, Utah, and California. Salmonella enteritidis is being reported with increasing frequency from states in the Middle and South Atlantic Regions. A hospital-associated outbreak of infection due to J5. enteritidis is currently under investigation in Richmond, Virginia. Increased activity of £>. enteritidis is also noted in reports from Maryland and Pennsylvania. The possibility that a product involved in interstate commerce in this area is the common source accounting for the increased activity is being considered. A comprehensive review of the status of salmonellosis in the State of Hawaii is included under Special Reports in this issue. Further studies on the frozen turkeys implicated in the large outbreak of gastroenteritis in Boulder County, Colorado (SSR No. 35) are included under Food & Feed Surveillance.
