Salmonella surveillance report ; no. 42, OCTOBER 28, 1965

For the Month of September 1965.During September, 2,518 human isolations of salmonella were reported for an average of 504 per week. This represented an increase of 32 over August and a decrease of 21 from the figure for September, 1964 (See Figure 1).The cumulative number of reported human recoveries through September (15,585) was less than the comparable figure for 1964 of 15,970 (See Table I). The indication is that 1965 will represent a decrease from 1964 in reported human isolations.A total of 652 nonhuman recoveries were reported during September for a decrease of seven from the previous month.A Salmonella saphra alert, prompted by the occurrence of 10 cases in Texas during the past six weeks appears under CURRENT INVESTIGATIONS.Included under Reports from the States this month is a report on a recent outbreak of Salmonella heidelberg gastroenteritis in New Jersey and a review of typhoid fever in California in 1964. A review of salmonellosis in Korea and a report of the second quarter isolations of salmonellae in the Netherlands are included under the International Section.Continued interest in the problem of contamination of brewer's yeast and cottonseed meal with salmonellae is reflected in reports of surveys of these items by state and federal laboratories in the Food and Feed Surveillance Section.I.
