In his paper “The Effects of Herbicides in South Vietnam,” Dr. Gerald C. Hickey—who was affiliated with Cornell University’s Southeast Asia Program when the paper was published by the National Academy of Sciences, National Research Council—describes the effects of defoliants on Vietnamese highlanders. The highlanders’ descriptions of the effects of herbicides on their land, animals, and their own health are in many cases similar to those of Americans who have been exposed to herbicides.
There was a definite pattern in the perceptions regarding the effects of the herbicides on those residing in or near the sprayed zones. The most common symptoms reported were abdominal pains and diarrhea. Informants from Long Djon also reported that in addition to these symptoms, the villagers complained of experiencing a stinging sensation in their nasal passages just after the spray drifted into the settlement. Many developed coughs that lasted more than a month. At Dak Rosa, according to some residents, many villagers went into the swiddens following the spraying, and in addition to the common symptoms noted above, these people broke out with skin rashes that lasted many weeks. Dak Tang Plun residents also reported widespread skin rashes, cramps, diarrhea, and fevers. A Plei Ro-O informant reported these same symptoms, noting that some villagers coughed blood.
Polei Krong informants stated that the villagers suffered these same ailments, that the skin rashes looked “like they had been burned, with small blisters all over the red areas.” Dak Siang informants noted that after some of the villagers drank from the stream which was in the sprayed area, they became ill with abdominal pains and diarrhea that lasted for days. They also reported that some villagers had eaten bamboo shoots from the sprayed area, after which they became dizzy “like you feel when you have drunk too much from the wine jar,” and this was followed by vomiting. Polei Krong residents, according to one informant, fell ill with abdominal pains, diarrhea, vomiting, and fever within one day after the spraying…
A difficult area of inquiry concerned possible deaths due to the herbicides. Sickness and death are common occurrences in highland villages, and infant mortality is particularly high. Some of the informants expressed the opinion that there was an unusually high number of deaths, particularly among children, following the spraying. However, they were very cautious in concluding that the spraying affected childbirth.
Informants from Long Djon had reported a stinging in the nasal passages just after the spray drifted over the settlement, and this was followed by villagers being afflicted with coughs. They added that more children than adults were afflicted, and that “many children died.” The victims developed skin rashes, and those with rashes that did not clear up died. One elderly lady noted that she knew of one stillborn case following the spraying, but she could not say whether it was due to the herbicide (she, like other informants, always pointed out that stillbirths were not unusual in their villagers). At Dak Rosa informants attributed the outbreak of skin rashes to the fact that many villagers went into the swiddens following the spraying. They also noted that some women carried their small children on their back in the fields, and they brushed against leaves containing the “medicine” that had been sprayed. Some of these children subsequently developed bad rashes all over their bodies. They looked, the informants said, “like insect bites,” and all the victims died. One informant knew of three such deaths. Another informant reported knowing of five stillbirths after the mothers, during pregnancy, had worked in the sprayed swiddens. The informants felt that there was an unusually high number of such deaths following the spraying.
Most of the informants interviewed reported widespread deaths among their domestic animals following the spraying. The Long Djon informants noted that since they were refugees they had few animals, but most of their chickens and pigs died shortly after the spraying, and the Dak Rosa villagers reported the same thing. Informants from Dak Tang Plun said that all of their chickens, most of their pigs, and some of their cattle died, and the young man from Plei Ro-O reported the same thing, specifying that this occurred within four or five days after the spraying. He also noted that villagers found a number of dead wild animals, particularly wild boar, in the nearby forests. Polei Krong informants also pointed out they found dead wild boar in the forest. They, too, saw all of their chickens, pigs, dogs, and small cattle die, although big cattle survived. Both the Polei Kleng and the Plei Jar Tum villagers said that their pigs, dogs, and chickens died, and the latter added that they also lost cattle. Plei Ngol Drong informants reported that all of the pigs, chickens, dogs, goats, (they noted that goats are “very strong”), and cattle died…
Although some of these reports may sound highly exaggerated, Dr. Hickey and others have pointed out that before the US sprayed their villages and farmlands, the highlanders of Vietnam had never been exposed to synthetic drugs or chemicals, and it is conceivable that their susceptibility to herbicides was much greater than that of people living in highly industrialized nations where even tests on young children have demonstrated that their bodies contain residues of synthetic substances. Some areas of Vietnam were also sprayed repeatedly with Agent Orange containing levels of TCDD hundreds of time higher than the dioxin content of 2,4,5-T now in use in the United States. Yet even after Dow had “refined” its production process to reduce the content of dioxin in 2,4,5-T, the effects of this herbicide on animals and humans have been extremely toxic, although without a national effort to determine just how many people have become ill, died, lost their farm animals, and left their land because of herbicide spraying, the full extent of the problem may never be known.
Consider, for example, the case of Eve and Vern DeRock, who were living on a farm in an Oregon valley sprayed by International Paper Company in March 1977. One week after the spraying, fifteen of the DeRock’s experimental cows aborted their calves. But like so many people who believed that “killing off a few weeds” would never do anyone harm, the DeRocks dismissed the miscarriages as “bad luck” and tried to re-breed their heifers. Out of fifty-four, only six conceived and the DeRocks, totally unaware that TCDD could be stored in beef fat, wound up butchering a few cows for their own use and selling the rest. The following spring when the surviving cows gave birth, five of their offspring were born with gross deformities and died within four days. Soon the DeRocks began experiencing stomach pains, loss of strength, and “summer colds” that seemed to resist ordinary treatment. Following a fire in an area of their farm that had been treated with herbicides just a few weeks earlier, Vern collapsed. And after a series of tests, doctors performed exploratory surgery on Eve, only to discover chronic liver failure, sending her home with the expectation that she would die as soon as her liver stopped functioning.4
But through all this the DeRocks did not stop eating the beef and butter they had stored in their freezer. No one from the company that was spraying herbicides or a state or federal health agency appeared to explain to them how dioxin gets into the food chain and consequently into the human body. More than a year after their land had been sprayed and their lives disrupted, if not ruined, the DeRocks happened to see a documentary on Vietnam veterans that explained the health effects of Agent Orange. The documentary also described the research of Vietnamese doctors who have linked Agent Orange to liver cancer in their own country, and the very next day the DeRocks stopped eating the meat and butter they had stored. Their health began to improve, but they have not been compensated for their suffering and, they realize, the Vietnamization of Oregon continues. Even after the emotional and financial hardships the DeRocks have endured, they cannot be sure that the helicopters will not return—there is no law to prevent them from doing so.
