The question for our political leaders is has the issue attained a critical level of public consciousness for further unwarranted actions to be taken?

Topic: Irridiation Policy in US Public School Lunch Programs
INTRODUCTION
According to a 2002 audit by the General Accounting Office, outbreaks of food borne illness in U.S. schools have increased at a yearly rate of about 10 percent. In 1999, there were 50 school-related outbreaks nationwide with 2,900 illnesses. Supporters of irradiation say it could reduce the number of food borne illnesses.
The 2002 Farm Bill directs the USDA to not prohibit the use of approved food safety technologies on foods purchased for the National School Lunch Program. This legislation effectively opened the door for the purchase of irradiated beef products with federal funds.
On May 29, 2003 the U.S. Department of Agriculture released specifications for the purchase of irradiated ground beef in the National School Lunch Program. The use of this technology is not mandatory. Local school districts have the option of ordering irradiated beef products to be served in their school cafeterias. While several consumer groups have expressed concern that irradiated beef is unsafe, there is additional concern that students and families are not informed when these products are being served. The USDA strongly encourages schools to provide information to school employees and student families, but they lack the authority to mandate the provision of this information.
The USDA’s Food and Nutrition Service provided all school districts with an informational package to prepare them to decide whether to order irradiated beef products. In addition, the package included a brochure with answers to commonly asked questions about irradiation.

IRRADIATION PROCESS
Defined
Radiation is broadly defined as energy moving through space in invisible waves. Radiant energy has differing wavelengths and degrees of power. Light, infrared heat and microwaves are forms of radiant energy. So are the waves that bring radio and television broadcasts into our homes.
The radiation of interest in food preservation is ionizing radiation, also known as irradiation. These shorter wavelengths are capable of damaging microorganisms such as those that contaminate food or cause food spoilage and deterioration. Sources of ionizing radiation used on food products include gamma rays, X-rays and electron beams. Gamma rays are radioactive fission products of Cobalt60 and Cesium-137. Cobalt60 is the most widely used source of gamma radiation. It is produced by exposing natural cobalt59 to neutrons in a nuclear reactor, where the reaction between the two species yields the radioactive cobalt60.
Advantages
Irradiation is known as a cold process. It does not significantly increase the temperature or change the physical or sensory characteristics of most foods. An irradiated apple, for example, will still be crisp and juicy. Fresh or frozen meat can be irradiated without cooking it.
During irradiation, the energy waves affect unwanted organisms but are not retained in the food. Similarly, food cooked in a microwave oven, or teeth and bones that have been X-rayed do not retain those energy waves.
Ionizing radiation can eliminate or greatly reduce the populations of microbial pathogens, and extend the shelf life while preserving the desired nutritional and sensory properties of refrigerated poultry and red meat. Food borne pathogens can be greatly reduced in population and sometimes completely eliminated from foods by low doses of ionizing radiation.
Disadvantages
When food is hit with enormous doses of gamma rays (usually from cobalt-80) radiotoxin molecules are created. The FDA calls these molecules “radiolytic by-products” and classifies them into two categories, known and unknown. The known category includes such compounds as formaldehyde and benzene. The unknown category is defined as chemical molecules that have not been characterized and are not found anywhere in nature.
Vitamins E, K, the entire B group, amino acids and essential fatty acids are all known to be adversely affected. Irradiation also accelerates the growth of a nasty mold called aspergillus. This mold produces potent natural carcinogens called aflatoxins. One study conducted by the FDA itself in 1979, demonstrated that food irradiation increases aflatoxin production by more than one-hundred-fold.
The irradiation process only penetrates up to 1-2 inches. Not all pathogens are surface phenomenon, which may create a false sense of security.
The bactericidal efficacy of a given dose of irradiation is also dependent on the following factors:
* the type of organism;
* the numbers of organisms (or spores) originally present;
* the composition of the food;
* the presence or absence of oxygen;
* the physical state of the food during irradiation,
* and the condition of the organisms.
------------------------------------------------------------------------
HISTORY OF IRRADIATION IN THE UNITED STATES
1921: A patent was granted for the process to kill Trichinella spiralis in meat by using x-ray technology.
1963: The Food and Drug Administration (FDA) approved irradiation to control insects in wheat and flour.
1964: The FDA approved irradiation to inhibit sprouting in white potatoes.
1971: The FDA approved irradiation of several packaging materials.
1985: The FDA approved irradiation at specific doses to control T spiralis in pork.
1986: The FDA approved irradiation at specific doses to delay maturation, inhibit growth, and disinfect foods, including vegetables and spices. The Federal Meat Inspection Act [administered by United States Department of Agriculture (USDA)] was amended to permit gamma radiation to control T spiralis in fresh or previously frozen pork.
1990: The FDA approved irradiation for poultry to control Salmonella and other food borne bacteria.
1992: The USDA approved irradiation for poultry to control Salmonella and other food borne bacteria.
2000: The USDA’s regulations were amended to allow irradiation of refrigerated and frozen uncooked meat, meat byproducts, and certain other meat food products to reduce levels of food borne pathogens and to extend shelf life.
2003: The USDA approves irradiated beef within the public school lunch programs.

PRIMARY STAKEHOLDERS
Irradiation Industry
The irradiation industry would favor the use of irradiation as a matter of economic survival. Irradiated beef currently accounts for less than 5% of overall meat sales.
.
USDA/FDA
The USDA and FDA support the use of irradiation in the public school system. The USDA states that protection of the public from food borne illness is a priority. The FDA concluded that irradiation is safe in reducing disease-causing microbes and that it does not compromise the nutritional quality of treated products.
Public School Boards
Public school boards have little incentive to purchase irradiated beef. The additional cost ($0.13 to $0.20 per pound, approximately 16%) would place an unacceptable burden upon an already financially stretched system. The salience of concerned parents would cause numerous debates over the issue, thus turning public school systems away from the controversy. If the irradiation process is accepted, the public school system may also benefit from the protection against tort lawsuits in the event a child is sickened by contaminated beef products. However, they may also incur lawsuits from unknown long term effects from the use of irradiation.
Beef Industry
The beef industry will greatly favor irradiation of beef products in the public school system. They believe it twill serve as a protective measure against negative public perception and civil liability in the event of contaminated beef products causing an outbreak of food borne illness.
Students/Parents
Students and parents may not even be aware that irradiated beef is being used in the public school system. Irradiated meat will arrive at schools with labels indicating they have been treated by irradiation; however, notification to students and parents is not required. Although there has been little evidence to support the assertion that irradiated beef may potentially be harmful, there is resistance to its use in the schools by some students and family members.
The World Health Organization, American Medical Association and
American Dietetic Association
All three of these groups endorse irradiation as a means to protect against harmful pathogens.
Consumer Groups
Various consumer groups argue that the process destroys vitamins and nutrients and can develop chemicals that are linked to birth defects and cancer, and strongly oppose its use. Consumer surveys have also shown that the vast majority of consumers believe the most effective way to reduce the risk of foodborne illness from bacteria in meat is for people at home to take more care to properly prepare and cook meat.
The Center for Food Safety and The Institute for Agriculture and Trade Policy feel that more research is needed on irradiation’s safety before serving it to school children.
------------------------------------------------------------------------
PRIMARY POLICY PROPOSALS
The following policy proposals outline a course of action that may be implemented with regards to the approval of irradiated beef in the public school system.
1. Continue to provide irradiated beef products to schools who request them under the USDA’s existing regulations.
2. Continue to provide irradiated beef products to schools that request them, but require the school system to inform students and parents of the decision.
3. Reinstate the ban on the use of USDA funds for the purchase of irradiated beef products in school lunch programs.
4. Prohibit the serving of any beef products which have undergone irradiation compliant with USDA specifications.
5. Require all public school lunch programs to use beef products that are treated with irradiation.
------------------------------------------------------------------------
GROUP ENDORSEMENT
Prohibit the use of irradiated products in federally funded school lunch programs until more extensive research becomes available and other measures against food borne illnesses are addressed.
Public Health Benefit From Our Proposal
* Risks associated with long term effects of irradiation will not be passed on to uniformed students.
* Supporters of irradiation will not get a quick fix to global sanitation problems.
* Sanitation practices will have to be improved.
* Will not promote a false sense of security.
* Research for safer alternatives to improve sanitation may be investigated.
* Parental distrust of school boards will not occur.
Economic and Social Costs
* Increased cost of beef will not be passed on to school boards and parents.
* Less time and money will be spent on dealing with concerned students and parents.
* School boards may need to be proactive and invest into developing additional sanitation practices.
* May incur costs associated with alternative federal mandate solutions to food safety.
* Less public distrust.
* Potential tort lawsuits.
Administrative Feasibility
* Repealing the current policy will provide the least complicated solution to administrative problems within the public school lunch program.
* However, the food borne illness issues will not be solved unless:
* Federal legislation implements a more diligent sanitation program.
* The meat/food industry makes significant advances to internal practices.
* School boards take another step to go above and beyond the existing requirements including:
* Additional training
* Awareness programs for staff and students
* Disclosure to parents/students about current regulations would not be an issue.
* The school boards will no longer be the center of the controversy.
Political Considerations
The meat/food industry represents a powerful lobby and the issue of irradiation is primarily driven by financial considerations. We believe the USDA and FDA will never have appropriate funding or legislation necessary to inspect and enforce more stringent regulations upon the beef industry. The USDA and FDA are looking for quick fix to a global health issue. Politicians generally want to avoid conflict; by eliminated the option of feeding irradiated beef to uninformed school children, public distrust will be avoided.
Other political considerations include:
* Environmental issues with irradiation facilities.
* Irradiation of meat may open the doors to additional low cost imported beef thereby exacerbating the problems faced by family farms.
* Additional concerns about possibly contributing to the globalization of the food industry.
