Brazil's Bolsonaro Green-Lights 150+ Pesticides This Year

Politics

By Sue Branford and Thais Borges

With the ruralist lobby now in control of key sectors of the federal government, Brazil is rapidly approving new pesticides for use, some of which critics say are either unnecessary or excessively toxic. During the first 100 days of the Jair Bolsonaro administration, the Agriculture Ministry authorized the registration of 152 pesticides, putting Brazil on course to authorize more pesticides this year than in any previous year. Brazil is already the world's largest user of pesticides.

The number of pesticides authorized each year has risen rapidly, from 139 in 2015 under the Dilma Rousseff administration, to 450 in 2018 under the Michel Temer government (see graph). An even higher number is expected to enter the Brazilian market this year, as the Agriculture Ministry considers registration of roughly another 1,300 pesticides. Most of these requests are coming from foreign multinational companies, mainly based in the U.S., Germany and China, which is increasingly becoming an important supplier.

Pro-Pesticide Government vs. Environmentalists

Despite the rapid rise in authorizations, Bolsonaro's agriculture minister, Tereza Cristina, said "there is no general liberation" of new pesticide registrations. According to her ministry, the products will merely give farmers a greater choice of existing pesticides, and access to new chemicals and there is no reason to be concerned: "The use [of pesticides] is completely safe, provided they are applied as instructed, within a context of good farming practice and with the use of individual protective equipment," said the government.

Events within Brazil seem to deny the truth of Cristina's claims. Brazil has a higher per capita consumption of pesticides than any other country in the world — 7.3 liters per year per person — and it is already facing a serious problem with pesticide intoxication.

According to Guilherme Franco Netto, an Environment, Health and Sustainability Specialist at the Oswaldo Cruz Foundation, one of the world's top public health research institutions, about 100,000 cases of intoxication are recorded in Brazil each year. According to Alan Tygel, from the Permanent Campaign Against Pesticides and for Life, this figure seriously underestimates the real situation, as many rural workers fail to report pesticide intoxications.

Brazil: Pesticide Poisonings in Rural Areas

In July 2018, the human rights organization, Human Rights Watch, published a report documenting acute intoxication at seven locations in Brazil, including indigenous communities, schools and quilombolas — communities of runaway slave descendants.

"Pesticides sprayed in large plantations intoxicate children in schoolrooms in many parts of Brazil," said Richard Pearshouse, assistant director of the environmental and human rights division of Human Rights Watch. But the report found that many local inhabitants were too frightened to speak out.

In five of the seven impacted communities, people said they were afraid of suffering reprisals if they complained. In 2010 a rural farmer was shot dead after putting pressure on local government to forbid aerial spraying of pesticides — a common application practice in Brazil, even though it allows wind-carried toxic sprays to settle far from crops in surrounding communities and natural areas.

New Formulations Raise Alarms

Many of the requests given the go-ahead this year are for new formulations of already authorized pesticides."Once the initial manufacturer loses its patent, other companies start requesting registration so they can use the [same] active ingredients to produce new agricultural products," said Murilo Souza, from the State University of Goiás.

Leonardo Melgarejo, vice-president of the Brazilian Association of Agroecology, believes that this practice is harmful as it will inevitably lead to a big increase in consumption nationwide. "We are approving several variations of the same pesticide," he said. "We're heading for a situation in which farmers will be able to 'self-medicate,' with two pesticide shops on every block." Little research has been done to see how hundreds of various pesticides might interact to become more damaging.

The torrent of new approvals is also making it easier for Brazil's farmers to gain access to toxic pesticides with which the global community has serious concern. One such case is that of 2,4-D, an active ingredient in controversial defoliant Agent Orange, used by the U.S. Army during the Vietnam War and whose use is increasingly being controlled in other countries, after the World Health Organization's International Agency for Research on Cancer classified it in 2015 as "possibly carcinogenic to humans."

The latest wave of Agriculture Ministry authorizations seen on 10 April, gave the go-ahead to 31 products via an official federal decree — Act 24 — including three new formulations of 2,4-D requested by multinational pesticide makers and distributors. One request came from the Chinese company, Rainbow Defensivos Agrícolas, while the other two were initiated by Dow AgroSciences for formulations to be manufactured in South Africa and exported to Brazil.

These new Brazilian authorizations took place at a time when the Rio Grande do Sul Public Ministry, a group of independent public litigators, was carrying out an investigation into an allegation made by the Brazilian Wine Institute that last year the state lost almost a third of its grape harvest as a result of the aerial spraying of pesticides containing 2,4-D. Farmers spray this pesticide before they sow soy — also a time when grape, apple and olive trees are flowering, and when the spray can easily drift over neighboring farms.

"The data from our survey [that showed a loss of almost a third of the grape harvest] is a conservative figure, as it relied only on information spontaneously offered by farmers," said Helio Marchioro of Brazilian Wine Institute. In fact, grape farmers themselves are calling for a 2,4-D ban, even as the Bolsonaro administration approves new 2,4-D formulations.

Controversial Pesticides Approved for First Time in Brazil

Several of the pesticides authorized this year will be entirely new to Brazil. Some have already been classified by Brazil's National Health Surveillance Agency as "extremely toxic." These include: mancozeb, a broad-spectrum fungicide used in agriculture and horticulture; the fungicide fluazinam; and the insecticide chlorpyrifos. In 2018 the Pest Management Regulatory Agency banned the use of mancozeb in Canada, except for foliar use on potatoes, due to "unacceptable risks to human health." The U.S. Environmental Protection Agency (EPA) banned the use of chlorpyrifos in 2018 after its use had been associated with development disabilities in children.

One particularly controversial newly approved chemical is sulfoxaflor. This pesticide was one of several believed to have caused an outbreak in Brazil of colony collapse disorder — the catastrophic sudden disappearance of worker bees from a bee colony, leading to the death of hives. According to a survey carried out by Agência Pública and Repórter Brasil, half a billion bees were found dead in four Brazilian states in the first quarter of 2019 — a staggeringly large die off posing a threat to the pollination of fruits and vegetables and to native vegetation.

But at a press conference on April 9, Agriculture Minister Cristina seemed unaware that Brazil has already authorized sulfoxaflor. "The problem with the bees is that a product called sulfoxaflor was used. This [toxin] is not registered in Brazil," she said. "It probably entered Brazil illegally and is being used incorrectly and thus caused the death of the bees." In fact, sulfoxaflor was authorized at the end of last year by the Temer administration, though the official decree was only issued in January of this year under the Bolsonaro government.

Sulfoxaflor is classified by Brazil's National Health Surveillance Agency as "averagely toxic," but this evaluation is challenged abroad. Dow Chemical initially developed sulfoxaflor as a safer alternative to neonicotinoids, known to be harmful to bees. It was initially approved by the US EPA in 2013, a decision reversed in 2015 when studies found that sulfoxaflor was also dangerous to bees. Today sulfoxaflor can still be used in the U.S., but only in restricted circumstances.

Pesticide Deregulation in the Works

Environmental activist Alan Tygel believes that the rapid rise in the number of pesticide authorizations is directly linked to the growing power of the bancada ruralista agribusiness lobby in Congress. This lobby, he said, made its support for the impeachment of President Dilma Rousseff in 2016 dependent on government backing for pro-agribusiness measures. "From then on, the counterweight that came from progressive sectors, from family farming and from agroecology, was lost, and today the ruralist agenda faces fewer obstacles in its drive to have more pesticides approved and to push through more permissive laws," Tygel said. The Bolsonaro presidential campaign greatly benefited from ruralist support, and it greatly helped sweep the former Army captain and legislator to victory last October.

The next goal of the ruralist agenda — more permissive laws — may well get a major boost this year with congressional approval of PL 6299/2002, dubbed as the "poison package" by critics. The legislation, which would greatly deregulate pesticides, was endorsed by a Chamber of Deputies commission in June 2018 and it now awaits plenary debate. The Temer government justified the bill, presented to Congress by then Agriculture Minister and dedicated ruralist, Blairo Maggi, claiming that the country desperately needed to simplify the complicated process of getting new pesticides authorized in order to help farmers.

But Castro Moreira, president of the prestigious Brazilian Society for the Progress of Science, representing more than 100 scientific societies, disagreed strongly. He said at the time that the bill, "could have very serious consequences for the health of the Brazilian population and the environment … Its approval would be a backward step, because it follows the logic of mechanized agriculture, with high investments in fertilizers and pesticides, which is an outmoded way of thinking, dating from the end of the Second World War."

Current Agriculture Minister Cristina is a strong proponent of PL 6299/2002, but there is bound to be opposition to the bill's approval, though it will likely be difficult for critics to block the measure. The ruralists have never had a stronger grip on both the legislative and executive branches, and they seem determined to press their agribusiness agenda.

As President Bolsonaro ended his first 100 days in office, his popularity was slipping fast, with 30 percent of the population already assessing his administration as "very bad" and the markets believing the government is becoming unstable. However, that very perception of growing uncertainty seems to have only caused the ruralists to move forward with greater urgency. Meanwhile, conservationists and food experts continue to warn of the national and global environmental and health repercussions of Brazil's deregulated pesticide use — permissiveness likely to soon outstrip that seen among other major agricultural nations.

On Monday and Tuesday of the week that President Donald Trump held his first rally since March in Tulsa, Oklahoma, the county reported 76 and 96 new coronavirus cases respectively, according to POLITICO. This week, the county broke its new case record Monday with 261 cases and reported a further 206 cases on Tuesday. Now, Tulsa's top public health official thinks the rally and counterprotest "likely contributed" to the surge.

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Niq Steele / Getty Images

The patient in the case report (let's call him Tom) was 54 and in good health. For two days in May, he felt unwell and was too weak to get out of bed. When his family finally brought him to the hospital, doctors found that he had a fever and signs of a severe infection, or sepsis. He tested positive for SARS-CoV-2, the virus that causes COVID-19 infection. In addition to symptoms of COVID-19, he was also too weak to move his legs.

When a neurologist examined him, Tom was diagnosed with Guillain-Barre Syndrome, an autoimmune disease that causes abnormal sensation and weakness due to delays in sending signals through the nerves. Usually reversible, in severe cases it can cause prolonged paralysis involving breathing muscles, require ventilator support and sometimes leave permanent neurological deficits. Early recognition by expert neurologists is key to proper treatment.

We are neurologists specializing in intensive care and leading studies related to neurological complications from COVID-19. Given the occurrence of Guillain-Barre Syndrome in prior pandemics with other corona viruses like SARS and MERS, we are investigating a possible link between Guillain-Barre Syndrome and COVID-19 and tracking published reports to see if there is any link between Guillain-Barre Syndrome and COVID-19.

Some patients may not seek timely medical care for neurological symptoms like prolonged headache, vision loss and new muscle weakness due to fear of getting exposed to virus in the emergency setting. People need to know that medical facilities have taken full precautions to protect patients. Seeking timely medical evaluation for neurological symptoms can help treat many of these diseases.

What Is Guillain-Barre Syndrome?

Guillain-Barre syndrome occurs when the body's own immune system attacks and injures the nerves outside of the spinal cord or brain – the peripheral nervous system. Most commonly, the injury involves the protective sheath, or myelin, that wraps nerves and is essential to nerve function.

Without the myelin sheath, signals that go through a nerve are slowed or lost, which causes the nerve to malfunction.

To diagnose Guillain-Barre Syndrome, neurologists perform a detailed neurological exam. Due to the nerve injury, patients often may have loss of reflexes on examination. Doctors often need to perform a lumbar puncture, otherwise known as spinal tap, to sample spinal fluid and look for signs of inflammation and abnormal antibodies.

Studies have shown that giving patients an infusion of antibodies derived from donated blood or plasma exchange – a process that cleans patients' blood of harmful antibodies - can speed up recovery. A very small subset of patients may need these therapies long-term.

The majority of Guillain-Barre Syndrome patients improve within a few weeks and eventually can make a full recovery. However, some patients with Guillain-Barre Syndrome have lingering symptoms including weakness and abnormal sensations in arms and/or legs; rarely patients may be bedridden or disabled long-term.

Guillain-Barre Syndrome and Pandemics

As the COVID-19 pandemic sweeps across the globe, many neurologic specialists have been on the lookout for potentially serious nervous system complications such as Guillain-Barre Syndrome.

Though Guillain-Barre Syndrome is rare, it is well known to emerge following bacterial infections, such as Campylobacter jejuni, a common cause of food poisoning, and a multitude of viral infections including the flu virus, Zika virus and other coronaviruses.

Studies showed an increase in Guillain-Barre Syndrome cases following the 2009 H1N1 flu pandemic, suggesting a possible connection. The presumed cause for this link is that the body's own immune response to fight the infection turns on itself and attacks the peripheral nerves. This is called an "autoimmune" condition. When a pandemic affects as many people as our current COVID-19 crisis, even a rare complication can become a significant public health problem. That is especially true for one that causes neurological dysfunction where the recovery takes a long time and may be incomplete.

The first reports of Guillain-Barre Syndrome in COVID-19 pandemic originated from Italy, Spain and China, where the pandemic surged before the U.S. crisis.

Though there is clear clinical suspicion that COVID-19 can lead to Guillain-Barre Syndrome, many important questions remain. What are the chances that someone gets Guillain-Barre Syndrome during or following a COVID-19 infection? Does Guillain-Barre Syndrome happen more often in those who have been infected with COVID-19 compared to other types of infections, such as the flu?

The only way to get answers is through a prospective study where doctors perform systematic surveillance and collect data on a large group of patients. There are ongoing large research consortia hard at work to figure out answers to these questions.

Understanding the Association Between COVID-19 and Guillain-Barre Syndrome

While large research studies are underway, overall it appears that Guillain-Barre Syndrome is a rare but serious phenomenon possibly linked to COVID-19. Given that more than 10.7 million cases have been reported for COVID-19, there have been 10 reported cases of COVID-19 patients with Guillain-Barre Syndrome so far – only two reported cases in the U.S., five in Italy, two cases in Iran and one from Wuhan, China.

It is certainly possible that there are other cases that have not been reported. The Global Consortium Study of Neurological Dysfunctions in COVID-19 is actively underway to find out how often neurological problems like Guillain-Barre Syndrome is seen in hospitalized COVID-19 patients. Also, just because Guillain-Barre Syndrome occurs in a patient diagnosed with COVID-19, that does not imply that it was caused by the virus; this still may be a coincident occurrence. More research is needed to understand how the two events are related.

Due to the pandemic and infection-containment considerations, diagnostic tests, such as a nerve conduction study that used to be routine for patients with suspected Guillain-Barre Syndrome, are more difficult to do. In both U.S. cases, the initial diagnosis and treatment were all based on clinical examination by a neurological experts rather than any tests. Both patients survived but with significant residual weakness at the time these case reports came out, but that is not uncommon for Guillain-Barre Syndrome patients. The road to recovery may sometimes be long, but many patients can make a full recovery with time.

Though the reported cases of Guillain-Barre Syndrome so far all have severe symptoms, this is not uncommon in a pandemic situation where the less sick patients may stay home and not present for medical care for fear of being exposed to the virus. This, plus the limited COVID-19 testing capability across the U.S., may skew our current detection of Guillain-Barre Syndrome cases toward the sicker patients who have to go to a hospital. In general, the majority of Guillain-Barre Syndrome patients do recover, given enough time. We do not yet know whether this is true for COVID-19-related cases at this stage of the pandemic. We and colleagues around the world are working around the clock to find answers to these critical questions.

One of the initial reasons social distancing guidelines were put in place was to allow the healthcare system to adapt to a surge in patients since there was a critical shortage of beds, ventilators and personal protective equipment. In fact, masks that were designed for single-use were reused for an entire week in some hospitals.

Democratic presidential hopefuls Joe Biden and Senator Bernie Sanders greet each other with a safe elbow bump before the start of the Democratic Party 2020 presidential debate in a CNN Washington Bureau studio in Washington, DC on March 15, 2020. Mandel Ngan / AFP / Getty Images

By Jake Johnson

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.

"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."

The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."

In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."

"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."

 

The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.

Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."

"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."

Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."

"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.

On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.

Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.

"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.

Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."

 

Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."

Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."

"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."

"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."
