Q

Foodborne Illness

what is a foodborne outbreak

A

When two or more people get the same illness from the same contaminated food or drink, the event is called a foodborne outbreak.

Public health officials investigate outbreaks to control them, so more people do not get sick in the outbreak, and to learn how to prevent similar outbreaks from happening in the future. http://www.cdc.gov/outbreaknet/outbreaks.html

Q

Norovirus

A

A very contagious virus
You can get norovirus from an infected person, contaminated food or water, or by touching contaminated surface
The virus causes your stomach or intestines or both to get inflamed (acute gastroenteritis)
Prevention – hand washing, avoid contact with infected people

20
Q

Norovirus

A

Symptoms
Stomach pain
Nausea
Diarrhea
Vomiting

Treatment
Non-specific
Fluid replacement
Self limiting

21
Q

Calicivirus

A

Similar to norovirus in symptoms and treatment
Caused by a different virus

22
Q

Government Action to Prevent Foodborne Disease

A

Federal, state and local agencies are responsible for protection of the public from foodborne illness

23
Q

FDA and Department of Agriculture (USDA)

A

Responsible for ensuring foods are safe, wholesome and properly labeled
Regulate the safety of the food supply
Inspect products, promulgate and enforce regulations, work with the industry to improve safety

24
Q

USDA

A

Responsible for safety of meat and poultry, including products containing more than 2% of cooked meat or poultry, and eggs
Requires inspection of processing plants daily
Requires presence of inspector on site whenever a slaughtering plant is in operation

25
USDA
Account for about 20% of federally regulated foods Account for about 27% of foodborne illness outbreaks Has the power to ban importing of meat and poultry from countries with inferior food safety systems
26
FDA
Responsible for all other foods, including seafood, produce, grains Responsible for about 80% of federally regulated foods Account for about 67% of reported foodborne illness outbreaks
27
FDA
Inspections may occur once every 10 years Don’t inspect farms unless there is an outbreak Does not have the power to ban importing of fruits, vegetables, grains or fish from countries with inferior food safety systems (but the USDA does!)
28
USDA/FDA
Many inconsistencies between the 2 agencies, what are they? Issues with the system Patchwork legislation Division of responsibility Lack of coordination
29
USDA/FDA
Inconsistencies among different types of food in the way food safety is regulated System depends too heavily on detecting and correcting problems after they occur rather than focusing on prevention
30
HACCP
HACCP: Hazard Analysis Critical Control Point Originally invented by NASA to ensure food safety in outer space A proactive approach to food safety Focuses on procedures Implemented by the Clinton administration as a preventive approach to meat and seafood safety
31
HACCP
Puts the responsibility on food businesses to analyze their procedures Requires government inspectors to verify compliance Identifies potential sources of contamination and devises ways to avoid them Should reduce the need for inspections The USDA reports nearly 96% compliance
32
HACCP Procedures
Conduct a hazard analysis Determine the critical control points Establish critical limits Establish monitoring procedures Establish corrective actions Establish verification procedures Establish record-keeping and documentation procedures
33
HACCP Procedures
Very similar to other cause and effect/failure mode and effects analysis models
34
Irradiation of Food
The use of radiation to kill microbial contaminants of food Opposition among consumer groups FDA has approved irradiation of red meat, poultry, pork, fruits and vegetables, seeds, herbs and spices, eggs and wheat Foods that have been irradiated must be labeled as such Controversial?
35
CDC Program PulseNet
Consists of public health laboratories in all 50 states and Canada Network permits timely comparisons of pathogens that may cause outbreaks in various parts of the country Identifies common sources of contamination Enables public health officials to take action to halt distribution of contaminated foods Passive surveillance (waits for information to be reported by doctors, hospitals, labs)
36
CDC Program FoodNet
An active surveillance network Designed to help public health officials better understand the epidemiology of foodborne diseases Contact labs, survey physicians, contact members of the general public
37
CDC Program FoodNet
Data collected provides information on less severe foodborne illnesses that are often not reported to public health authorities Data helps officials at the USDA and FDA identify where their regulatory systems should be improved Includes investigators at the USDA and FDA and ten state health departments
38
Additives and Contaminants
Food safety standards include limits on additives and contaminants in food Additives are intentional, purposely incorporated into food to improve taste, color, nutritional value and resistance to deterioration
39
Contaminants Detected by Inspection Include
Dirt Hair Rodent feces Insect parts Pesticide residues Hormones Antibiotics
40
Drugs and Cosmetics
Prescription and OTC drugs regulated by FDA though different levels of regulation exist between the two Complex system for new drug approval Cosmetics more loosely regulated No requirement for safety testing Warning label must be on products not tested
41
Food and Drug Labeling and Advertising
Regulations established in 1994 require labels on prepared foods to contain information on Fats including saturated and trans-fats Fiber Vitamins Other nutrients and recommended daily intakes for these nutrients
42
Politics of the FDA
FDA regulates products accounting for approximately 25% of consumer dollars spent FDA criticized for Being too slow in approval of new drugs (criticism from the drug companies) Being too ready to approve new drugs (criticism from consumer advocates)
43
Politics of the FDA
FDA’s issues led to a review by the IOM which recommended Increased funding for improved monitoring of the safety of drugs post marketing Greater authority for the FDA to require companies to conduct follow-up clinical studies on newly detected adverse effects
44
Politics of the FDA
Congress passed legislation in 2007 that addressed some of these recommendations Reauthorized the use of user fees for the drug approval process Increased funding for post-marketing studies and surveillance Granted the FDA authority to require companies to conduct follow-up clinical studies on newly detected adverse effects
45
Safe Food and Drugs
What is the role of the pharmacist?: Education Regulation compliance OTC medication recommendation Referral to primary care providers Others?
