Environmental Links to Health Concerns
• Drinking Water
• Food
• Land
• Built Environment
• Indoor Air
• Emergencies
Foodborne Illness Definitions
• Outbreak the occurrence of two or more cases of a similar illness resulting from the ingestion of a common food. (CDC)
•Agro-terrorism: [Terrorism] directed against agriculture, livestock, or other food supplies with biological, chemical, or [physical] radiological weapons. (FBI)
Importance of Preventing Foodborne Diseases
• Many are ill or die– 76 million US cases each year (estimated) – Of these…,
• 325,000 hospitalized• 5,000 died (CDC)
• Cost in 2000: $6.9 billion per year for 5 bacterial pathogens (USDA/ERS)
Potential Impacts
• Death and illness
• Economic consequences
• Panic/alarm• Loss of
confidence, or disruption, in food supply
Complex System, Many Food Interests
Food can be contaminated at any point, from farm inputs to fork.

Inputs
Potential Contaminants in Food
• Microbes and microbial toxins – Salmonella, Clostridium botulinum
• Chemicals– Cleaners, pesticides
• Physical hazards– Glass, Radioactive contaminants
Rajneeshee Religious Group Most “successful” food terrorism yet . . .
751 reported cases of salmonella poisoning linked to 10 Oregon salad bars
1984 criminal investigation, but intent actually revealed by ex-follower in 1985
Why? Plan to make certain voters sick, so chosen candidates would win and support group in land dispute
Strategies: Community/Retail Standards Protect Consumers
• Adherence to existing standards1. Verification and Assurance
2. Common Sense Management Plans
3. Hazard Analysis Critical Control Points
4. Active Managerial Control of Risk Factors
…BUT…be aware… “Complete Safety” cannot be assured!
- Do I know my process/product?– Am I aware of what could cause a
problem?– Do I understand how to control threats?– Have my key employees been involved in
planning?– Has effective training occurred?
2. Common Sense Management Plans
3. Hazard Analysis Critical Control Points (HACCP)
• A system for ensuring safe food production
• May be used from “Farm to Fork”
The objective is to make the product safely and to be able to prove it!-- Bill Schafer, U of M
HACCP Principles
1. Hazard Analysis
2. Critical Control Point
3. Criteria/Standards
4. Monitoring
5. Corrective Action
6. Record Keeping
7. Verification/Validation
4. Active Managerial Control (AMC) of Risk Factors
• System for controlling risk
• Places responsibility on establishment
• Manager certification
• On-going worker education
• Recognizing accomplishment of safe food!
Strategies: Surveillance (Finding Illness and
Confirming with Lab Testing)
• FoodElert– 24/7 emergency contacts for the food industry
• Sharing of food testing results by government labs (FoodNet, PulseNet)
• Poison Control Centers (FERN)
MN Public Phone number: 1- 877- FOOD ILL
(1- 877- 366-3455) to report foodborne illness
• Federal: Information Sharing and Assessment Centers (PDD 63: www.fas.org/irp/offdocs/pdd/pdd-63.htm)
• Food Center is one of 8 ISACs www.fmi.org/isac/• Members can report national food threats
– fax web form to (202) 323-2079 or (202) 323-2082
Strategies: Public-Private Collaboration
Strategies: Communication
The Health Alert Network Links all local and state public health
agencies Alerts public health contacts, health care
providers, emergency workers, etc.
Summary
• Private and public cooperation is required to maintain and strengthen the food system.
• Following established guidelines will enhance security, including watching for signs and symptoms of: chemical , biological, and physical contamination.
• Core public health measures help ensure safer food, including: assessing threats, developing common sense and
practical policies, communicating, and assuring food safety standards are met.
