MORE PET FOOD CONTAMINATION NEWS--FDA AND NY TIMES - MAY 8, 2007
Sent: May 8, 2007
The Opinion Page of the May 7 on-line version of the NY Times demands that the FDA be given more legal authority, money and inspectors so that the safety of both imported animal and human food can be ensured. It may be that thousands of our pets have died as the result of contaminated food from China--the same thing could happen to human beings.
It continues, saying that the FDA upgraded its food safety programs last week, creating the position of Commissioner for Food Protection and naming a highly respected scientist to fill it. Although this should focus attention on this subject, the writer feels that nothing much will change until Congress provides money and legal authority to police overseas producers.
The FDA, which is in charge of monitoring the vast majority of the food supply, has no program to check the adequacy of foreign regulatory systems and inspects a tiny fraction (1%) of imports.
Congress, the writer states, must give the FDA authority to evaluate food safety systems and plants in all countries that export food to us. The Chinese, especially, should be required to fully open their procedures to FDA inspection.
If you feel the above is needed, please contact your State and Federal congressional representatives and urge them to do what is needed to save both animal and human lives.

Second--from the FDA/USDA on the danger (or lack thereof) to people:
FDA/USDA Joint News Release: Scientists Conclude Very Low Risk to Humans from Food Containing Melamine
FDA Press Office: 301-827-6242
USDA Press Office: 202-720-4623
There is very low risk to human health from consuming meat from hogs and chickens known to have been fed animal feed supplemented with pet food scraps that contained melamine and melamine-related compounds, according to an assessment conducted by scientists from five federal agencies.
In the most extreme risk assessment scenario, when scientists assumed that all the solid food a person consumes in an entire day was contaminated with melamine at the levels observed in animals fed contaminated feed, the potential exposure was about 2,500 times lower than the dose considered safe. In other words, it was well below any level of public health concern.
The risk assessment is an important new science-based component of the continuing federal joint investigation into imported wheat gluten and rice protein concentrate from China that contained melamine and melamine-related compounds.
The risk assessment was conducted by scientists from the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) of the Department of Health and Human Services (HHS), the Environmental Protection Agency (EPA), U.S. Customs and Border Protection (CBP) of the Department of Homeland Security (DHS) and the Food Safety and Inspection Service (FSIS) of the U.S. Department of Agriculture (USDA). This team is now compiling a scientific assessment of the risk to animal health associated with ingestion of animal feed containing melamine and its compounds.
FDA and USDA are in the process of identifying a group of experts to convene a scientific advisory board that would be charged with reviewing the risk assessment. This group would also be asked to contribute to future scientific analysis related to the risk of melamine and its compounds to humans and animals.
In the course of the investigation, it was discovered that pet food was contaminated by wheat gluten and rice protein concentrate that contained melamine and its compounds. Subsequently, scraps of contaminated pet food that contained only low levels of melamine were distributed to farms in a limited number of states and added to the feed consumed by swine and poultry. These scraps constituted only a small percentage of the farm animal rations. In addition, melamine is known to be excreted in animal urine. When exposure levels are much higher, as was the case with cats and dogs, the melamine and its compounds appear to cause the formation of crystals in the kidney systems, resulting in kidney damage. There was no indication of kidney damage in hogs. Both hogs and chickens known to have been fed contaminated feed appear to be healthy.
This dilution factor was an important piece of data considered in the multi-agency science-based human risk analysis and helps to support the conclusion that there is very low risk to human health from eating meat from animals that were fed the contaminated product. This conclusion supports the decision announced on April 28 not to recall meat from animals that were fed contaminated product.
Currently, swine and poultry on farms suspected of receiving contaminated feed are being held under state quarantine or voluntarily by the owners. In several cases, feed samples have tested negative for melamine and related compounds. These tests were conducted by federal laboratories or state laboratories using approved methods. It is assumed that because only small amounts of the contaminated feed were mixed with other rations, the melamine and related compounds were no longer detectable. USDA has concluded that, based on the human risk assessment and the inability to detect melamine in the feed samples, these animals no longer need to be quarantined or withheld from processing.
In other cases, feed samples have tested positive for melamine and related compounds; feed samples were not available; or feed samples have not yet been submitted for testing. These animals continue to be withheld from processing, but are not yet being culled, pending the results of the animal risk assessment. This assessment is expected to be completed within one week. At that time, USDA will determine whether these animals can be released for inspection and further processing.
USDA and FDA continue to conduct a full and comprehensive investigation. As additional information is confirmed, updates will be provided and decisions will be made using the best available science to protect the public's health.
To ensure no further contaminated products enter the U.S., the federal government will continue to monitor imported wheat and corn gluten as well as rice protein concentrate and isolates arriving from all countries destined for human and animal consumption. The FDA import alert for these products sourced from China remains in effect and U.S. Customs and Border Protection will continue laboratory testing of the products as they enter the U.S. The inspections are a precautionary measure to ensure the safety of products entering at U.S. ports of entry. There is no evidence to suggest products bound for the human food supply are contaminated.
For additional information about the pet food and contaminated feed investigation, go to www.fda.gov or www.usda.gov. The human safety/risk assessment will be available online upon completion of an executive summary.
