title: Food-borne tonsillopharyngitis outbreak in a hospital cafeteria.
abstract: OBJECTIVE
  A food-borne tonsillopharyngitis outbreak was reported between 9th and 13th of February, 2008, in Söke State Hospital, Aydın, Turkey.
  
  
  METHODS
  This descriptive cohort study was carried out immediately after the outbreak. In order to determine the probable origin, a questionnaire involving demographical features, clinical features, and possible risk factors was distributed to 403 persons. The participants of the questionnaire (n = 403) were divided into two groups: the study group (n = 252); those with any two of the following three complaints; sore throat, fever, and dizziness, and the control group (n = 151); those without these complaints.
  
  
  RESULTS
  This investigation revealed that 252 people were affected by this outbreak. Group A β-hemolytic streptococci were isolated from the throat cultures of 63 affected individuals (25%) and an employee working in the patisserie that made desserts served for lunch. Since the number of people who ate the milky dessert was statistically higher compared to the non-eaters, the milky dessert was thought to be the origin of the outbreak.
  
  
  CONCLUSIONS
  We suggest that throat infections among employees working in food production may cause outbreaks of upper respiratory tract infections.
