New Report Reveals Two-Thirds of European Honeybee Pollen Contaminated By Dozens of Pesticides

More than two-thirds of the pollen that honeybees collect from European fields is contaminated by a cocktail of up to 17 different toxic pesticides. These are the shocking findings of a new study released yesterday.

In addition to pesticides-related chemicals, the report also identifies substances used in insecticides, acaricides, fungicides and herbicides, produced by agrochemical companies like Bayer, Syngenta and BASF. To mark the release of the report and protest against the chemical industry's role in bee decline, more than 20 activists unfurled a giant banner outside the headquarters of Bayer, in Germany.

The study, The Bees' Burden: An analysis of pesticide residues in comb pollen (beebread) and trapped pollen from honey bees, is the largest of its kind, comprising more than 100 samples from 12 European countries. In total 53 different chemicals were detected.

The study is a snapshot of the toxicity of Europe’s current agricultural system. It demonstrates the high concentrations and wide range of fungicides found in pollen collected around vineyards in Italy, the widespread use of bee-killing insecticides in pollen from rape fields in Poland, the detection of DDE—a derivative of DDT—a pesticide banned decades ago, and the frequent detection of the insect nerve-poison Thiacloprid, a neonicotinoid, in many samples from Germany.

“This study on contaminated pollen reveals the unbearable burden of bees and other vital pollinators,” said Matthias Wüthrich, a Greenpeace ecological farming campaigner. “Bees are exposed to a cocktail of toxic pesticides. This is yet more proof that there is something fundamentally wrong in the current agricultural model which is based on the intensive use of toxic pesticides, large-scale monocultures and corporate control of farming by a few companies like Bayer, Syngenta & Co. It shows the need for a fundamental shift towards ecological farming.”

The report confirms the findings of a recent study carried out by the European Food Safety Authority (EFSA). In its study, EFSA acknowledges vast knowledge gaps related to the health of bees and pollinators, including on the effects of chemical "cocktails," and calls on the EU and national governments to fill this gap with further scientific investigation.

In light of its findings on pollen contamination and following EFSA’s recommendations, Greenpeace calls on the European Commission and policy-makers across Europe to:

  • Extend the scope of restrictions already imposed on the use of certain pesticides harmful to bees, namely clothianidin, imidacloprid, thiamethoxam and fipronil, so that their use is completely banned.
  • Fully ban all other pesticides harmful to bees and other pollinators (including chlorpyrifos, cypermethrin and deltamethrin).
  • Set ambitious Europe-wide action plans to better assess pesticide impacts on pollinators and reduce their use.
  • Encourage research and development of non-chemical alternatives to pest management and promote the widespread implementation of ecological farming practices on the ground.

The Navajo Nation have decided to stop pursuing the acquisition of a beleaguered coal-fired power plant in Arizona, locking in the plant to be taken offline and its associated coal mine to close later this year.

A Navajo Nation Council committee voted 11-9 last week to stop pursuing the purchase of the 2,250-megawatt Navajo Generating Station, which with the Kayenta coal mine provides more than 800 jobs to primarily Navajo and Hopi workers as well as tribal royalties.

A coalition of utilities that own the plant said in 2017 it would cease operations due to increased economic pressure, and the plant's future has proved a flash point for national and regional energy policy and raised larger questions on how Native communities will handle ties to fossil fuel industries as the economy changes.

Is it just us?

Other countries don't seem to have a problem getting their high-speed rail systems on track. This superfast, fuel-efficient form of mass transit is wildly popular throughout Asia and the European Union. Japan's sleek Shinkansen line, the busiest high-speed rail system in the world, carries an estimated 420,000 riders every weekday. In China, the new Fuxing Hao bullet train now hurries more than 100 million passengers a year between Beijing and Shanghai at a top speed of 218 miles an hour, allowing its riders to make the trip of 775 miles — roughly the distance from New York City to Chicago — in about four and a half hours. Spain, Germany and France together have more than 4,500 miles of track dedicated to high-speed rail, over which more than 150 million passengers travel annually.

Ocean Heroes Bootcamp

By Coda Christopherson (11) and Lea Eiders (15)

Growing up in a plastic-free home, I was sheltered from the plastic waste crisis. I (Coda) went to a very progressive school that had vegan lunch items, farm animals and ran on solar power. My mom produces zero-waste events and my dad is a sailor, so we're very passionate about the ocean. When I was nine years old, we moved back to Manhattan Beach, California and I started 3rd grade in a public school. This was the first time I really understood that plastic-free living is not the norm; single-use plastics were everywhere, especially in the cafeteria. Once I recognized this problem, I knew I had to make a difference.

A major California avocado producer issued a voluntary recall of the popular fruit over concerns they could be contaminated with Listeria monocytogenes, USA Today reported.

Henry Avocado issued the recall Saturday after a routine government inspection at its California packing facility turned up positive test results for the bacteria on "environmental samples," the company said in a statement. No illnesses have been reported.

Acting Secretary David Bernhardt visited Watson Hopper Inc., a manufacturer of rigs and oil drilling equipment in Hobbs, New Mexico on Feb. 6, 2019. Tami A. Heilemann / DOI

Oil executives gathered for a conference laughed about their "unprecedented" access to Trump administration officials, according to a recording obtained by Reveal from the Center for Investigative Reporting.

In the recording, taken at a June 2017 meeting of the Independent Petroleum Association of America (IPAA) at a Ritz-Carlton in Southern California, members expressed excitement about one official in particular: David Bernhardt, who had been nominated that April to be deputy secretary at the Department of Interior (DOI). Bernhardt would be confirmed the following month.

"We know him very well, and we have direct access to him, have conversations with him about issues ranging from federal land access to endangered species, to a lot of issues," IPAA political director Dan Naatz said in the recording.
