Environment
Same pathogens but novel sources Produce Convenience foods Sources other than food (pets, pet food, bottled
water) Norovirus-not just person to person
Environment
International food sources A global food market
Foodborne outbreaks or issues in other countries may impact us
Localized outbreaks vs. widespread outbreaks
Host
Enteric infections associated with international travel
Host
Public awareness Media Educational initiatives Labeling
Host
Consumer demands• Convenient/Eating out • Want local and fresh (12 months of the year)• Ethnic foods
Public Health
Integrated approach to surveillance Lab techniques help improve detection Communication with all partners
What’s next
Changes in host, pathogen and source Continue to see more food available, more
consumer choices What does this mean for public health and
the food industry? Keep people safe and healthy
