Second, surveillance for foodborne illness
does not always delineate illnesses from Salmonella
in shell eggs versus those from Salmonella
in egg products. The Centers for Disease Control
and Prevention (CDC) conducts surveillance for
illnesses from Salmonella through two programs:
the Foodborne Diseases Active Surveillance
Network (FoodNet) and the National
Salmonella Surveillance System of the Public
Health Laboratory Information System (PHLIS).
When a suspected outbreak of foodborne salmonellosis
is investigated, it is not always possible
to identify the food vehicle. Further, if a
vehicle is identified, it may be difficult to identify the precise nature of the ingredients in the
vehicle. Hollandaise sauce, for example, may be
implicated in an outbreak of illness, but whether
the sauce was made with shell eggs or egg
products may be unknown (CDC, 2005).
