Evans, Sanitary Engineer, Region V, Chicago, reports an outbreak of gastro-enteritis among persons on a train traveling between Chicago and Fort Pierce, Florida. It was stated that 15 passengers had diarrhea. Of these, only 1 was available for questioning as the others had debarked prior to arrival at Fort Pierce. Water was suspected to be the vehicle of infection and a sample was sent to Chicago for analysis. Samples of perishable foods were requested and instructions were given to obtain new stocks of these foods. Instructions were also given to flush and chlorinate the water systems. No labora tory reports are available at this time. Dr. Edward Lane, County Health Officer, New York State, reports an outbreak of gastro-enteritis among persons who dined at a country club. The number of persons eating at the club and the time of the meal was not given. There were 28 persons who became ill from 1 to 4 hours after the dinner. The order slips revealed that the only common item of food was cauliflower with cream sauce. The incubation period and the symptoms (sudden vomiting, diarrhea, abdominal distress, and some prostration) confirm the diagnosis of staphylococcus food poisoning. An investigation revealed that one of the food handlers who prepared the sauce had a 4-day-old cut on one palm. Other than this, the sanitary conditions prevailing among the food handlers in the kitchen were excellent. Table 1.
