Seven Steps for Approval of
Animal Health Products
Scientific Discovery
Bringing an animal health product to market is a complex process. Only one in 20,000
discovered chemicals ever makes it from the laboratory to the farm. And only one in 200
potential drugs makes it through pre-clinical testing and approval. All this takes time. It can
take three to four years to license a new animal vaccine, and a decade or more to take an
animal drug from discovery to approval. It's also expensive. In 1990, the animal health
products industry spent more then $400 million on research and development, twice what was
spent in 1980.
Preliminary Trials
Once a scientist discovers a new material that might be useful in animal health, the potential
product is put through a series of preliminary trials. Tests are conducted in test tubes, on
simple organisms such as bacteria, yeasts or mo!ds. New tools from biotechnology and
computer models are also used to determine how the compound behaves in living systems.
Pre-Clinical Trials
At the pre-clinical trial stage, tests are performed on animals to estimate the approximate
dosage and check for any adverse effects. If, after these trails, the company remains
convinced that the compound has potential, the appropriate federal agency is notified. The
Food and Drug Administration approves applications to investigate new animal drugs and
feed additives. The U.S. Department of Agriculture reviews research plans for vaccines or
other animal biologicals. The Environmental Protection Agency issues permits for some
experiments.
Clinical Trials
The fourth stage in the approval process involves clinical trials, with tests conducted to
ensure the safety and effectiveness of a product. Generally, the government assigns a team of
scientists to work with manufacturers to make sure that all necessary tests are conducted and
all data are reviewed. The regulatory agencies must be sure that , drugs used in animals don't
have residues in meat, milk or eggs, and they must determine how long it takes to deplete any
traces of the drug from edible products. If the compound will be used in pregnant animals or
if it leaves significant residues in tissues for a long time, breeding studies are undertaken to
determine if it is toxic to the embryo or causes birth defects. Researchers also conduct field
trials to demonstrate how the product works under typical farm conditions in various parts of
the country. In addition to conducting clinical trials, the manufacturer must be able to prove
that it can consistently produce a quality product.
Seven Steps for Approval
of Animal Health Products
Regulatory Review
With the clinical trials complete the tests are then
reviewed by the appropriate regulatory agency. If
the compound can be proven safe and effective, the
government will give the manufacturer permission
to produce and sell the product.
Product Approval
When a product is approved, its label becomes part of
the federal record. Because the label is a legal document, it
cannot be changed without government approval. Livestock
producers are required by law to adhere to label instructions
when they use an animal health products.
Monitoring
As a final check, the government monitors the food
supply for illegal drug residues. The FDA Milk Safety
Branch, along with state regulators, monitors the milk
supply, and the USDA Food Safety and Inspection
Service randomly tests slaughtered animals to ensure
that meat is free of illegal residues. Each year, FSIS
tests more than 40,000 samples for more than 100
animal drug and pesticide products. Over the last 10
years, the violation rate has steadily declined. In 1990,
only 0.3 percent of all samples tested showed illegal
levels.
