Chief Health Officer Dr. Lamont Sweet advised that, since the first case of E coli 0157:H7 was confirmed Thursday morning, a thorough investigation has begun. "So far, we have found that the water is clear, and that food preparation, food handling processes and hygiene practices are good," he said. "It is likely that the source of the bacteria is food borne. We will be taking every opportunity to determine the source; however, it is quite possible that we may not be able to identify where it came from."

Since October 29th, 14 patients and 31 staff members have experienced symptoms of E coli. Two patients of Hillsborough Hospital and one staff person were admitted to the Queen Elizabeth Hospital. The two patients died; however, the test results to determine whether they had the E coli bacteria are still not complete.

To date, two cases of E coli 017: H7 have been confirmed. Hospital staff are now conducting tests on all 75 patients, all Dietary staff, and all other staff who have had symptoms.

Cecil Villard, Director of Acute Care and Mental Health with Queens Region Health, advised that every precaution is being taken to support patients, families and staff. "We have been in touch with the families of all the patients at the hospital and everyone who may have received food from the hospital to see how they are and ensure they have the information they need," he said. "We are asking all staff who have had symptoms to stay home until their test results are clear. Food preparation and handling processes will continue to be monitored as an extra precaution."

Dr. Sweet advised that there have been no new cases presenting with symptoms since Wednesday, November 6th. "Symptoms usually appear between two and ten days after coming in contact with the bacteria," he said. "Health Canada is now assisting us in the investigation which includes conducting food histories on all those who have had symptoms."

Dr. Sweet advised that the best way for people to prevent becoming ill from E coli is to ensure that beef and poultry products are well cooked, and that fruits and vegetables are washed well.
