“Our FoodCORE-supported Team Salmonella has greatly improved our ability to conduct salmonellosis surveillance in New York City. We are now better prepared to obtain food histories and provide surge capacity during critical outbreaks.”

Program Highlight

In the fall of 2009, NYC DOHMH established Team Salmonella to improve surveillance for Salmonella infections. Since then, the timeliness and completeness of interviews have greatly improved. Complete and timely interviews help solve foodborne outbreak investigations. Before Team Salmonella, fewer than 10% of people with a Salmonella infection were interviewed. With Team Salmonella, the proportion of people interviewed has increased to a range of 85-90% annually.

Additionally, patients with a Salmonella infection are contacted within the same day of when NYC DOHMH receives the report from a health care provider or laboratory. This is significantly better than the 3 weeks it used to take before Team Salmonella was created. Overall, Team Salmonella has greatly improved NYC’s ability to investigate and solve suspected outbreaks.

Percent of People with Salmonella Infections Interviewed by Year, New York City, 2009-2015

Percent of People with Salmonella Infections Interviewed by Year, New York City, 2009-2015. Data—2009: 34%, 2010: 82%, 2011: 78%, 2012: 86%, 2013: 89%, 2014: 90%, 2015: 85%.Total number of Salmonella infections by year: 2009 (not available), 2010 (not available), 2011 (n=1169), 2012 (n=985), 2013 (n=1380), 2014 (n=1127), 2015 (n=986). This figure shows a bar graph that compares the percentage of people with Salmonella infections interviewed in New York City from 2009 - 2015. The height of each bar on the graph represents the percentage of people with Salmonella infections who were interviewed. The percentage of people interviewed dramatically increased from 2009 to 2010 when Team Salmonella began performing interviews in September 2009. Since then, the percentage of people interviewed has steadily increased. In 2009, only 34% of people with Salmonella infections were interviewed. In 2010, 82% were interviewed. In 2011, 78% were interviewed. In 2012, 86% were interviewed. In 2013, 89% were interviewed. In 2014, 90% were interviewed. And most recently in 2015, 85% were interviewed.
