This work is about getting data for policy from investigated outbreaks (not about detecting or investigating outbreaks)

Inves estigated ed O Outbrea eak Data: From om Good ood to o Great  Surveilla illance of in investig igated outbreaks is is u uniq ique  A peek eek beh ehind the e scen enes es  Estimation on of of food oodbor orne illness source attribution on  Extracting the data -- -- mak aking es estimates need eeded ed for policy Investigated outbreak data source: F oodborne Disease Outbreak S urveillance S ystem (FDOS S )

Foodborne D e Disea ease Outbreak S Surveillance System FDOSS SS Cap aptures data a from inves estigated ed o outbrea eaks on on agent nts, food oods, and settings respo ponsib ible le for illness illn Developed ed: 1973 Because: e: Outbreaks are the major way we learn what foods are causing illness and how to prevent it. Now: : S tates report hundreds of outbreaks each year through the National Outbreak R eporting S ystem (NOR S ). The data is used to determine pathogen-food combinations to target for prevention.

Goa oals of of Inves estigated ed Outbreak eak Surveill illance  Des escribe e char arac acter eristics of outbreak eaks  Determine major foods causing illness  Determine major agents causing foodborne illness  Determine settings for foodborne illness  Determine factors that repeatedly contribute to foodborne illness outbreaks  Obtai ain data a that can an be u e used ed to es estimate e food oodbor orne illness s illn source attrib ibutio ion Investigated outbreak data source: F oodborne Disease Outbreak S urveillance S ystem (FDOS S )

What i is Unique a about Inves estigated ed O Outbrea eak Survei eillance? e?  Col ollects reports on on grou oups of of peop ople  with the same illness  (rather than individuals with that illness)  The e food that cau aused ed the e illnes ess can an often en be e det eter ermined ed with cer ertai ainty  (rarely possible with individual illnesses)  Outbreak eak r rep eports contai ain a a weal ealth of d data  broad range of illnesses, foods, settings  even “unsolved” outbreaks provide information on symptoms, agents, settings
