Montero JT, Anderson L, Greenblatt JF, Welch JJ, Talbot EA. New Hampshire Department of Health and Human Services, Concord, New Hampshire An outbreak of Salmonella enterica Enteritidis occurred in June - July 2003 in New Hampshire. During the outbreak, nineteen people were reported ill, three were hospitalized, and one developed kidney failure following the illness. All isolates had indistinguishable pulsed-field gel electrophoresis patterns when tested by Xba I and Avr II enzymes. Case interviews, cohort study and a case-control study were conducted. Statistical analyses revealed an association between disease and consumption of potato salad prepared by one local food establishment. Relative risk in the cohort study was 4.38 (95% CI 0.66 - 29.03), and odds ratio in the case-control study was 5.71 (95% CI 0.53 – 61.41). The Mantel-Haenszel odds ratio was 7.32 (95% CI 1.28 – 41.83). The food facility was inspected two weeks and one month after the disease onset of the last recognized case. There were no food samples or other environmental samples available for microbiological testing during the investigation. Three primary deficiencies were noted during the inspection: inadequate egg boiling technique; inappropriate storage of the finished product; and the use of multi-use rubber gloves for the mixing of potato salad. The multi-use gloves were not sufficiently cleaned and sanitized, were inappropriately stored and were used for the period of three-four weeks. Multi-use gloves may have contributed to this outbreak and official recommendations for their use must be clarified.
