Pesticides
Poisoning
Many of our wild felines, especially jaguars, have been purposefully
poisoned with pesticides used in several crops.
The most notorious agent is Carbofuran, marketed under many brand
names in Brazil - the best known being Furadan,
manufactured by FMC Corporation.
Farmers are well aware of jaguars’ eating habits. The cats
kill the prey, hide the carcass and return many times, until they
no longer find anything to feed from it. Farmers stuff granulated
poison – the worst form of all – into the prey’s
carcass and the jaguar will die and extremely painful death. It
is common knowledge that “just a handful will sure kill the
beast.”
What happens next? How many animal species – birds, reptiles,
insects – will be feeding from that same carcass? And after
this secondary killing, how many others will be feeding from their
carcasses in turn? The environment is thus directly contaminated,
and the effects on people and animals can easily be anticipated.
We selected a few testimonies and recent data involving Carbofuran
in Brazil and in other countries as well.
FURADAN (Carbamate)
“Of all carbamates, Furadan
is the most widely used as nematocide, insecticide and acaricide
in the great majority of developing countries - and in some other
countries too.
The price this popularity pays is contamination of foodstuff, air
and water – therefore with effects on man, mammals and fish.
The preference for this pesticide is due to the fact that alternative
products, such as organochlorides, have a longer list of toxicity
problems with residues, and organophosphates are not only more toxic,
but have a well-defined neurotoxic action as well.
The action mechanism of Furadan (cholinesterase
inhibitor) causes acute intoxication, generally leading to death
from inhalation or contact. All animals that touch a poisoned carcass
- vultures, flies or small carnivores - will be killed. When Furadan
is applied to crops in high wind – and we may have up to 70%
straying – birds, insects, reptiles and even fish are at risk.
A lethal Midas, it will kill whatever it touches.”

Jaguar in museum was killed by poison, was
the medical opinion.
BELÉM – The Forensic Institute in Pará published
the conclusion of the autopsy performed in a jaguar that lived in
the Emilio Goeldi Museum and was found dead last May. It was first
presumed the jaguar had fallen victim to ingestion of rodent control
product, but the institution proved that other products were used
for that purpose. The Museum director, Mr. José Malcher,
said that high doses of poison were found in the jaguar’s
stomach, bladder and blood.

Asbestos and pesticides on the list of dangerous products Experts
recommend that all forms of asbestos and three pesticides be included
in the Rotterdam Convention on dangerous products trade.Campinas,
SP – The Rotterdam Convention list of dangerous chemical products
must be revised, to include three pesticides and all forms of asbestos
among imports/exports subject to Previous Informed Consent.That
was the recommendation of an expert committee appointed by the Convention
signatory countries in charge of examining and assessing the risks
of nearly 70,000 chemicals currently sold in the international market,
and the nearly 1,500 launched every year. Inclusion of the four
new items shall be discussed at the next international meeting in
September.The Rotterdam Convention regulates international trade
of dangerous chemical products, requesting importing countries to
ban the ones that cannot be safely managed. Once allowed, imports
must be labeled and unequivocally identified, ensuring the right
to information.
The Convention has already been signed by 73 countries –
including Brazil – and ratified by 18. It will come into effect
once there are 50 signatory countries.The original products list
included 22 organic pesticides considered to be highly toxic, five
bromate and chloride industrial chemicals and one asbestos form
– the only mineral regulated by the Convention. Of the three
pesticides to be included by recommendation of experts, one is monocrotophos,
used as insect and acaricide control in cotton, rice, citrus and
corn, mainly in Asia. It is highly toxic for birds and mammals and
has intoxicated farm workers from respiratory depression.Also Granox
TBC and Spinox T, two formulations that mix fungicides and Carbofuran
insecticide were included. Carbofuran
has already been banned in 25 countries and was found to be the
cause of death of Senegal farm workers.The third fungicide is DNOC,
a mixture of insecticide, herbicide and fungicide, already banned
in Peru and in the European Union. Inclusion of all forms of asbestos
in the Rotterdam Convention was influenced by the mineral banning
in Australia, Chile and the European Union. Asbestos is carcinogenic
and leads to a pulmonary disease called “asbestosis”
upon inhalation of particles, when the asbestos is broken. “This
decision is a major step towards elimination of asbestos related
risks”, said Reiner Arndt, German, head of the experts committee.
“Even in countries like mine, where asbestos products were
banned a long time ago, we still have problems with decontamination
of old buildings and the high costs involved in treatment of people
affected by asbestos-related diseases”. In Brazil, asbestos
is banned in some States. A motion by the National Environment Council
(CONAMA) proposed that asbestos be banned throughout the country
in toys, brake linings, clutches and industrial equipment applications
by December 31, 2003, while water tanks, roof tiles and pipes would
be banned by 2005 and chloride-soda diaphragms by 2008.Environmentalists
and occupational health specialists consider this schedule too flexible.
In the State of São Paulo, ban on asbestos in brakes and
automotive parts started to be enforced in May this year. Liana

“However, the problem that affects ecosystems most –
especially where these have been simplified, like in the State of
Paraná – is soil treatment. Herbicides and pesticides
are the major threat in that region. Evidence to that is the article
– at the same time an outcry and an alert– published
in “O Jornal” in June 1983 under the heading “201
victims of pesticides in the Municipality of Maringá alone”.
An overview of the pesticide and herbicide contamination problem
in the State of Paraná indicates that in 1982/83 there were
a total of 1,600 cases of intoxication, and 26 deaths. The most
dangerous to health, and also responsible for the shockingly high
number of contamination cases were, according to the newspaper:
Endrex-20, totaling 187 victims; Nuvacron-400, 145; Furadan,
174; Folidol-60, 168; Azodrin, 149; Metaxystox, 131 cases. The people
most subject to contamination are farm workers who move from one
harvest to the next.”

Damages in other countries - Carbofuran
Carbofuran is one of the most effective
new poisons. Furadan 4-F, a carbofuran
product brought to us by FMC Corporation, was the poison that brought
down the birds in Bitter Lake. Carbofuran
chemicals are estimated to kill at least 1 to 2 million birds each
year in the United States alone. In 1994, restrictions were imposed
on FMC, but 2 million pounds of the poison in liquid form are still
used every year. The active ingredients in the chemical are lethal
to birds even when used as per the instructions on the label. According
to Birding Magazine, "Perhaps more than any other chemical,
carbofuran is used intentionally and
illegally to poison birds and other wildlife" (August 2000)

Poisoning
The laying of any poisoned bait is illegal, whether it is laid
to deliberately kill a bird of prey or whether it is laid for a
fox or magpie. A poisoned bait may take the form of an opened up
rabbit carcass or piece of meat which has been sprinkled with poison,
eggs that have been injected with poison - often discoloring the
contents of the egg - or the carcass of a pigeon, sheep etc. Many
poisons are fast acting, so that victims are often found close to
the baits.
In 2000 alone, 109 poisoning incidents were reported to the RSPB,
well over 10% of the total number of reported incidents. Alphachloralose,
Carbofuran and aldicarb were the most
commonly used poisons, but also used were mevinphos, dichlorovos
and strychnine. The use of carbofuran
in illegal baits has been growing over recent years, particularly
in Scotland.
Poisoned baits are indiscriminate and can be dangerous to wild
birds and other animals, and companion animals. Carrion feeding
birds such as buzzards and red kites are particularly vulnerable.
In 2000, 31 buzzards were known to have been killed, along with
10 red kites, two golden eagles and 15 peregrines. Fifty-one non
birds of prey were also killed, the majority of which were owls.
The UK Agricultural Departments run a poison hotline on 0800 321600,
on which suspected incidents of poisoning can be reported. If you
think you have found poisoned bait or victims, do not touch; warn
others to stay away, note the exact location and details of any
evidence, cover if possible, but don't destroy the evidence, and
phone the above number.

Poisoning of wildlife reported in January
to March 2001:
• Just a week after the seminar, a weakened and hungry Whitebacked
Vulture was found in the center of town, Mandume Avenue. Extreme
thirst and the debilitated condition of the bird makes poison ingestion
a prime possibility. He has recovered well and been released.
• A week later, thanks to publicity received on poisons and
pesticides, 150 weakened and very thirsty vultures were reported
from north east of Mariental. At a guess, poison - possibly low
dose intakes of aldicarb (also known as blougif), were suspected.
Mr Haindongo, the MET director for the southern region, was most
ready to assist these birds, but the local farming community felt
that they were able to provide the suggested assistance themselves.
Sheep and springbok were slaughtered and the birds were fed for
4 days. On the fifth day the last of the birds took to the air and,
as far as we know, none died.
• During the same week a farmer, approximately 250 km west
of the poisoned vulture event, contacted NARREC with a very ill
Martial Eagle. A fantastic response from the farmer got the eagle
to Windhoek in 4 hours. Two days after the initiation of treatment
the bird regurgitated a pellet with granules attached. The granules
indicate aldicarb, a highly toxic Carbofuran
that is sometimes misused in agriculture and also used illegally
as a rodent control. The pellet is being analyzed by the National
Forensic Science Institute, in Windhoek. Martial Eagles are not
generally scavengers, but this bird is only a two year old. The
question remains where did the eagle pick up this poison. (see unregistered
aldicarb at the end of this news). The bird has recovered and been
released
• A farmer 30 kilometers north of Windhoek is suspected of
poisoning dogs belonging to a large community living on neighboring
land. According to community leaders, the farmer sent samples of
poisoned meat into this community. Many dogs, cats and chickens
died. Four people were seriously poisoned through secondary poisoning
and had to be hospitalized.

An Avenging Angel on the Trail of the Pigeons Poisoner
NewYork Times-Jan 13,2000 By ROBIN FINN
NEW YORK -- As sympathetic victims, common urban pigeons -- even
those murdered by the elusive poison-wielding serial killer who
has been stalking them in Manhattan for the past two years -- are
a tough sell.
Mark MacDonald, a detective for the American Society for the Prevention
of Cruelty to Animals, who has become the guardian angel of all
living local pigeons and an avenging angel for the deceased, accepts
that the 8 million or so pigeons that use New York as their personal
coop-and-poop receptacle will never be mistaken for man's best friend.
The ancient Egyptians and Romans found pigeons most useful when
cooked; Venice recently dealt with its pigeon overpopulation problem
by gassing 20,000 birds. In New York, exterminators can use avitrol,
a legal poison, to eliminate nuisance birds who befoul the terraces,
windows and canopies of the city's luxury abodes. MacDonald bemoans
but accepts that, too.
"For every 50 pigeons killed today, there's 50 more born tomorrow,"
he says. But propagation isn't the point. What MacDonald doesn't
accept is mean-spirited murder, especially murder with a domino
effect that has also killed hawks, peregrines, sparrows, bluejays
and a pair of Central Park mallards: "This Mr. Evil is never
going to make pigeons an endangered species," asserts the gray-muzzled
MacDonald, who slicks his hair back Eddie Munster-style and whose
investigative mode is equal parts DeNiro, Columbo and Dumbo (he
says it helps to play dumb when you're about to confiscate an illegal
or battered pet or to collar the ringleaders and patrons at pit-bull
and cock fights).
Against the pigeon killer, though, MacDonald is trying to play
it smart. He has to: "He's going to make my life miserable
until he makes a mistake and we catch him, and God forbid the poison
does trickle down to a child or a domestic pet before we get him."
“With or without public sympathy, but with the support of
"National Geographic Explorer," which ran a special about
his efforts last Sunday on CNBC (it will be rebroadcast on Saturday),
MacDonald is staying his course. There's a killer on the loose,
and he intends to find him, cuff him and charge him with animal
cruelty, now a felony that commands a four-year jail term and $2,500
fine.
It's an unsolved metropolitan mystery where the trail has turned
cold after more than a thousand deaths. The detective has nightmares
about the elusive bird-hater who continues to toss an illegal and
terribly toxic poison, carbofuran,
into city streets and parks where pigeons congregate. Accustomed
to achieving closure in his cases, MacDonald has become obsessed
by his inability to do so with this one, now in its third year.”

Though the entire concept of Rid-A-Bird is just sick, there is
another pesticide that is more dangerous to nature. Called the black
plague of pesticides, it is carbofuran,
and it kills an estimated 2 million birds a year. The poison is
extremely, extremely toxic: once, a sheep rancher put out some to
kill coyotes he thought were killing his sheep. Several coyotes
came and ate the poison. They died within minutes. Later, some eagles
came to eat the coyotes. They died with their heads still in the
coyote's bodies. Scattered around were several magpies which had
also tried to eat the coyotes. The terrifying thing about all these
poisons is that they are ALL PERFECTLY LEGAL. In fact, the government
encourages uses of many of them, and spends most of its research
money discovering new ways to kill innocent animals. It has banned
a few dangerous pesticides for use in the US, but continues to export
them to other countries.

Effects on Birds
Carbofuran is highly toxic to birds.
One granule is sufficient to kill a small bird. Bird kills have
occurred when birds ingested carbofuran
granules, which resemble grain seeds in size and shape, or when
predatory or scavenging birds have ingested small birds or mammals
which had eaten carbofuran pellets.
Carbofuran is very toxic to pheasants,
chickens, fulvous tree ducks and Japanese quail. Red shouldered
hawks have been poisoned after eating prey from carbofuran
treated fields (J. Wildlife Manage. 47(4):1129. 1983). Levels of
carbofuran occurring in Kansas fields
have been high enough to cause a reduction in the weight, food intake
and ability to move of adult male bobwhites (Arch. Environ. Contam.
Toxicol. 11(5):611-615.1982).
Effects on Fish
Carbofuran may be teratogenic to
frogs (Toxicol. Lett. 22(1):7- 13.1984). It is very toxic to trout,
Coho salmon, perch (Hdbk. Acut. Tox. Chem. Fish & Aqua. Invert.
1980), bluegills (8), and catfish (Toxicology 23(4):337-345.1982).
The 96-hour LD50 for fish is 150 ug/L.

FURADAN WILL BE BANNED AFTER 1998,
so alternate pesticides are being tested for control of rice water
weevils under the leadership of Dr. M.O. (Mo) Way, entomologist
at Texas A&M's Agricultural Research and Extension Center, Beaumont.
Furadan was banned because its misuse
has caused bird kills.
Furadan has long been the most effective
pesticide for control of water weevils, the number one insect pest
of rice in Texas. But the U.S. Environmental Protection Agency has
banned use of the insecticide, whose chemical name is carbofuran,
after 1998 because its misuse has resulted in bird kills.
"We're evaluating pesticides to replace Furadan,"
says Dr. M.O. (Mo) Way, entomologist at the Texas A&M University
Agricultural Research and Extension Center at Beaumont.

Carbofuran-LETHAL EFFECTS
In acute toxicity tests with aquatic organisms, LC-50 (96h) values,
with only one exception, exceeded 130 ppb. The exception was the
larva of a marine crab with an LC-50 (96h) value of 2.5 ppb. In
tests of longer duration with fish, safe concentrations were estimated
to range between 15 and 23 ppb. Among the most sensitive species
of birds tested, the acute oral LD-50 was 238 ppb (?g/kg body weight),
the dietary carbofuran LD-50 value
was 190 ppm, dermal LD-50's exceeded 100 ppm, and the LC-100 value
in drinking water was 2 ppm. Mammals were comparatively resistant,
having LD-50 acute oral toxicities >2 ppm, a dietary LD-38 of
100 ppm after 8 months, and dermal LD-50's >120 ppm. However,
only 2 ppb as an aerosol killed 50% of rhesus monkeys in 6 hours,
and 40 ppb killed all pheasants within 5 minutes. Bees and earthworms
were relatively sensitive to carbofuran, but test conditions were
sufficiently different to preclude a strict comparison with vertebrate
species. Among photosynthetic species, concentrations of 200 ppm
carbofuran partly inhibited germination
of rice seeds, but not other species tested, after exposure for
24 hours. Effects of carbofuran on
plants are considered negligible when contrasted to faunal damage
effects.
Carbofuran administered to birds
in the diet for 5 days, plus 3 days postexposure on an untreated
diet, produced 50% kill values of 140 to 1459 ppm dietary carbofuran;
younger birds were more sensitive than older ones (Table 5). Food
consumption in groups of Japanese quail (Coturnix japonica) with
high carbofuran-induced mortality was
markedly depressed during the first 3 days of treatment (Hill and
Camardese 1982). Red-winged blackbirds, the most sensitive bird
species tested in food repellency tests, consumed a normal ration
of food contaminated with carbofuran
(Schafer et al. 1983). As a result, carbofuran
has a high potential for causing acute poisoning episodes in birds
(Schafer et al. 1983). Field application of carbofuran
granules to corn, at planting, in Maryland during 1980 was presumed
to be responsible for deaths of songbirds (order Passeriformes)
and white-footed mice (Peromyscus leucopus); all organisms contained
high levels of carbofuran in the gastrointestinal
tract and liver, suggesting extensive feeding in treated fields
(Balcomb et al. 1984a). A similar situation occurred in Perry, Florida,
after treatment of pine seed orchards (Overgaard et al. 1983). Laboratory
studies with house sparrows (Passer domesticus) and red-winged blackbirds
demonstrated that ingestion of a single carbofuran
granule is fatal to either species (Balcomb et al. 1984a,b). In
groups of old-field mice (Peromyscus polionotus) fed 100 ppm dietary
carbofuran for 8 months, mortality
was 38%; however, growth, development and behavior was normal among
survivors from this group and their offspring (Wolfe and Esher 1980).
In a preliminary study with rats and old-field mice fed 100 ppm
of dietary carbofuran, parents lost
weight (but none died), and the survival of young was reduced (Wolfe
and Esher 1980)
