Editing Mary Mallon (section)

===Career===
From 1900 to 1907, Mallon worked as a cook in the New York City area for eight families, seven of whom contracted typhoid.{{sfn|Elsevier|2013|p=56}}{{sfn|Walzer Leavitt|1996|p=16}} In 1900, she worked in [[Mamaroneck, New York]], where within two weeks of her employment, residents developed typhoid fever. In 1901, she relocated to [[Manhattan]], where members of the family for whom she worked developed fevers and [[diarrhea]]. Mallon then went to work for a lawyer and left after seven of the eight people in that household became ill.<ref name="TheStraightDope">{{cite web|author1=Dex|author2=McCaff|url=http://www.straightdope.com/columns/read/1816/who-was-typhoid-mary|title=Who was Typhoid Mary?|website=The Straight Dope|date=August 14, 2000|access-date=June 7, 2011|archive-url=https://web.archive.org/web/20171230172306/https://www.straightdope.com/columns/read/1816/who-was-typhoid-mary/|archive-date=December 30, 2017|url-status=live}}</ref>{{sfn|Adler|Mara|2016|pp=140–141}}

In June 1904, she was hired by a prosperous lawyer, Henry Gilsey. Soon four of the seven servants were ill. No Gilsey family members were infected because they resided separately, and the servants lived in their own house. Immediately after the outbreak began, Mallon left and relocated to [[Tuxedo Park, New York|Tuxedo Park]],{{sfn|Soper|1939|p=703}} where she was hired by George Kessler. Two weeks later, the laundry worker in his household was infected and taken to [[St. Joseph's Regional Medical Center]], where her case of typhoid was the first in a long time. The investigator Dr. R. L. Wilson concluded that the laundry worker had caused the outbreak, but he failed to prove it. The laundry worker died soon afterward.{{sfn|Adler|Mara|2016|p=137}}

In August 1906, Mallon began a job in [[Oyster Bay (hamlet), New York|Oyster Bay]] on [[Long Island]] with the family of a wealthy New York banker, Charles Elliot Warren.{{sfn|Campbell Bartoletti|2015|p=180}} Mallon went along with the Warrens when they rented a house in Oyster Bay for the summer of 1906. From August 27 to September 3, six of the 11 people in the family came down with typhoid fever. According to three medical doctors, the disease at that time was "unusual" in Oyster Bay. The landlord, understanding that it would be difficult to rent a house with the reputation of having typhoid, hired several independent experts to find the source of the infection. They took water samples from pipes, faucets, toilets, and the cesspool, all of which were negative for typhoid.{{sfn|Marineli|Tsoucalas|Karamanou|Androutsos|2013}}{{sfn|Soper|1939|p=699}}<ref>{{cite web|url=https://orauportal.fda.gov/courseware/FD202W100/SCORM_FD202_Module_3_Microbiology/Module_3_Dinner_With_Typhoid_Mary.pdf|title=Dinner With Typhoid Mary|website=FDA|access-date=July 1, 2018|archive-url=https://web.archive.org/web/20191221191421/https://orauportal.fda.gov/courseware/FD202W100/SCORM_FD202_Module_3_Microbiology/Module_3_Dinner_With_Typhoid_Mary.pdf|archive-date=December 21, 2019|url-status=dead}}</ref>
