Stop Forcing Chemicals Down Animals’ Throats


Target: Senate President Pro Tempore, Patrick Leahy

Goal: Ban the cruel force-feeding of chemicals to animals during research experiments

New findings, led by environmental health scientist Laura Vandenberg at the University of Massachusetts Amherst, reveal that the method of force-feeding chemicals down the throats of animals, known as “oral gavage,” does not give an accurate indication of those chemicals’ effects on humans. Oral gavage typically involves pumping chemicals through an animal’s mouth with a tube or a syringe for days at a time.

In her report, Vandenberg recommends abandoning the technique of oral gavage due to its lack of accurate data. She writes, “We conclude that gavage may be preferred over other routes for some environmental chemicals in some circumstances, but it does not appropriately model human dietary exposures for many chemicals. Because it avoids exposure pathways, is stressful and thus interferes with endocrine responses, gavage should be abandoned as the default route of administration for hazard assessments of EDCs.”

According to PETA, pharmaceutical tests that involve gavage tubes “…have an appalling 92 percent failure rate in predicting the safety and/or effectiveness of pharmaceuticals.” The health and safety of animals used in these tests are often completely disregarded. Gavage tubes are also used to fatten up ducks who are raised for foie gras. In this case, a massive amount of grain is shoved down the throats of birds, so that their livers grow to severely unhealthy sizes.

There has never been any question regarding the inherent cruelty involved with oral gavage, but Laura Vandenberg’s study shows that the method causes animals so much stress that it is impossible to conduct an accurate study on the effects of any given chemical. By signing this petition, you will be urging government officials to save animals from unnecessary cruelty by banning this torturous technique once and for all.


Dear Mr. Patrick Leahy,

Environmental health scientist Laura Vandenberg recently found that the animal testing technique of oral gavage does not provide accurate data on the effect of chemicals in humans. Oral gavage, a method that involves force-feeding animals chemicals through a syringe or tube, causes animals so much stress that it is impossible to get accurate results.

Gavage is the same method that is used to force-feed ducks massive amounts of grain, so they can be fattened up and killed for foie gras. It is a horrifyingly cruel process and it needs to be banned.

Please use your status as Senate President Pro Tempore to save animals from unnecessary abuse by passing legislation that bans the cruel, ineffective method of oral gavage once and for all.

    Vivisection is not the answer, there are non animal alternatives. No animal should be tortured to death for the foolish choices humans make. Animal experimentation is also faulty science.
