“…An outbreak of Shigella dysenteriae associated with consumption of coconut milk dessert has been reported in Thailand (Hoge, Bodhidatta, Tungtaem, & Echeverria, 1995), and more recently, Denmark and Australia have reported outbreaks of S. Sonnei associated with baby corn imported from Thailand (Lewis et al, 2007). Although culture-confirmed Shigella incidence isolated from patients with diarrhea in Thailand is 0.6/1000 population per year (von Seidlein et al, 2006), we did not isolate any Shigella in this study.…”

“…This relationship between food and pathogen was recognized by Table 1. Selected recent multinational foodborne outbreaks due to contaminated produce items [3,6,7,[9][10][11] Year Pathogen outbreak investigators even before the complex cycle of vertical transmission in the egg-laying hens and internal contamination of eggs was understood [22]. Even more dramatically, the first recognized outbreak of E. coli O157 infections heralded both the newly recognized foodborne pathogen and what turned out to be its predominant food vehicle, ground beef [23].…”

The growing burden of foodborne outbreaks due to contaminated fresh produce: risks and opportunities

2009

View full text Add to dashboard Cite

Foodborne outbreaks from contaminated fresh produce have been increasingly recognized in many parts of the world. This reflects a convergence of increasing consumption of fresh produce, changes in production and distribution, and a growing awareness of the problem on the part of public health officials. The complex biology of pathogen contamination and survival on plant materials is beginning to be explained. Adhesion of pathogens to surfaces and internalization of pathogens limits the usefulness of conventional processing and chemical sanitizing methods in preventing transmission from contaminated produce. Better methods of preventing contamination on the farm, or during packing or processing, or use of a terminal control such as irradiation could reduce the burden of disease transmission from fresh produce. Outbreak investigations represent important opportunities to evaluate contamination at the farm level and along the farm-to-fork continuum. More complete and timely environmental assessments of these events and more research into the biology and ecology of pathogen-produce interactions are needed to identify better prevention strategies.

“…Outbreaks of shigellosis have been associated with crowded conditions and poor personal hygiene, such as in prisons, daycare centers, schools and psychiatric institutions [5][6][7][8][9]. Large-scale outbreaks of foodborne shigellosis have been caused by infected food handlers practicing poor standards of personal hygiene [10][11][12][13]. Information on predominant sources and transmission routes of infections is crucial for targeted prevention of foodborne illnesses, and outbreaks frequently offer the only arena for gaining knowledge.…”

We report on the first foodborne outbreak of Shigella sonnei described in Austria. On July 14 2008, AGES was informed of a cluster of 22 laboratory-confirmed cases of infection with S. sonnei restricted to public health district X in the province of Salzburg. All cases had attended a youth-group trip to a small village in the province of Tyrol from July 7 to July 9. An outbreak case among the trip participants was a person who (1) attended the trip and (2) fell ill with diarrhea in the period between July 8 and July 12. Among the 61 trip participants, 42 fitted the outbreak case definition, including 31 culture-confirmed cases. A household outbreak case was a person who (1) did not participate in the trip, (2) fell ill with diarrhea not before July 10 and (3) had household contact with an outbreak case between one and three days before onset of illness. Of the 11 household outbreak cases, 10 were tested by stool culture and four of these had a laboratory-confirmed S. sonnei infection. In addition, one of the two hostel staff tested positive for S. sonnei. All 36 isolates were biotype gl, lysotype 12, and were indistinguishable from each other by PFGE. A cohort study among the trip participants revealed a risk ratio of 2.71 for consumption of salad (on at least 1 of the 3 days of the trip) (95% CI: 1.38-5.32, P = 0.004). Among the 42cases, 34 could be explained by consumption of salad. The landlady of the hostel, who prepared the salad with bare hands, was a carrier and was assumed to be the source of contamination of the salad. Without proper epidemiological analytical investigation of this shigellosis outbreak, its association with food consumption would not have been identified.

Outbreaks of shigellosis in Denmark and Australia associated with imported baby corn, August 2007 – final summary

Abstract: The recently reported concurrent outbreaks of Shigella sonnei infections in Denmark and Australia have been found to be linked to a common baby corn packing house in Thailand via trace-back of the distribution chain.
