Upon her release, Mallon was given a job as a laundry worker, which paid less than cooking—$20 per month instead of $50. After a time she wounded her arm and the wound became infected, meaning that she could not work at all for six months.<ref name=pbs/> After several unsuccessful years, she started cooking again. She used fake surnames like Breshof or Brown, and accepted jobs as a cook against the explicit instructions of health authorities. No agencies that hired servants for affluent families would offer her employment, so for the next five years, she worked in a number of kitchens in restaurants, hotels, and spa facilities. Almost everywhere she worked, there were outbreaks of typhoid.{{sfn|Soper|1939|pp=708–710}} However, she changed jobs frequently, and Soper was unable to find her.<ref name=TheStraightDope/>

In 1915, Mallon started working at [[Sloane Hospital for Women]] in New York City. Soon 25 people were infected, and two died. The chief obstetrician, Edward B. Cragin, called Soper and asked him to help in the investigation. Soper identified Mallon from the servants' verbal descriptions and also by her handwriting.{{sfn|Soper|1939|pp=708–710}}<ref name=pbs/>

Mallon fled again, but the police were able to find and arrest her when she took food to a friend on Long Island.<ref name=TheStraightDope/><ref name="isbe">{{cite web

Little is known about her life during the second quarantine. She remained on North Brother for more than 23 years, and the authorities gave her a private one-story cottage. As of 1918, she was allowed to take day trips to the mainland. In 1925, the physician Alexandra Plavska came to the island for an internship. She organized a laboratory on the second floor of the chapel and offered Mallon a job as a technician. Mallon washed bottles, did recordings, and prepared glasses for pathologists.{{sfn|Walzer Leavitt|1996|p=195}}{{sfn|Campbell Bartoletti|2015|p=141}}
