Our new investigation just out detailing how @EPA is still approving products that contain the worst pesticides

This includes pesticides that EPA has mandated use reductions or incentivized replacement like #chlorpyrifos, methyl bromide and #atrazine

biologicaldiversity.org/campaigns/pest…
I went through FOIA records on new pesticide products that were approved by the EPA in 2017-2018 and found that most new pesticide product applications, about 94%, are ultimately approved

*All denials were procedural in nature, not because the product was deemed too dangerous
A review of individual ingredients in the products that were approved from 2017 to 2018 indicated that many contain the most hazardous pesticides still in use, some of which have been banned by multiple other countries and even targeted for phaseout in the United States
Up first we’ve got the pesticide you love to hate: chlorpyrifos, with two products approved in 2017.

In fact there were 15 pesticide products approved with an organophosphate or carbamate in 2017-2018, including chlorpyrifos, malathion, acephate and oxamyl
Keep in mind, for the last 20 years EPA has been incentivizing approval of new pesticides that are supposed to replace organophosphates

So the EPA is publicly saying that it is pushing companies to replace OPs, yet it keeps approving new products as recently as last year
Next we’ve got the endocrine disruptor atrazine with 17 products! approved by EPA in 2017-2018

EPA actually got Syngenta to agree to modestly reduce the use of atrazine by 2020

Just one problem, all 17 new products are from companies other than Syngenta

(sigh)
2 products containing methyl bromide were approved in 2017 and 2018. Methyl bromide? Wasn’t that banned like 10 years ago?

Silly person, there are still exempted uses that it appears will never go away. Why we need more products for the handful of uses still left, I don’t know
Again, keep in mind that for the last 20 years the EPA has been fast-tracking approval of new pesticides that are supposed to replace methyl bromide.

Noticing a pattern yet?
EPA’s public face is to make you believe that the agency is moving in the right direction, replacing older pesticides with newer ones that are supposed to be safer.

But it’s not actually doing anything
Sure, incentives for replacements are great if you follow them up with hard deadlines to phase out a bad pesticide

But this is not being done. Nearly all pesticide cancellations in the U.S. are voluntarily done by industry

ehjournal.biomedcentral.com/articles/10.11…
You can’t keep approving pesticide products that contain the worst-of-the-worst pesticides and claim to be doing anything to reign in their use.
Other lowlights from 2017-2018 include:

EPA approved 6 products containing #paraquat

91 products that are "Restricted Use"

69 products that contain a pesticide the EPA has designated as a “known” or “likely” carcinogen

44 products containing a bee-killing #neonicotinoid
38 products containing #glyphosate – yes that’s right, 38 products for a single pesticide approved in 2 years

But watch out glyphosate, your “replacements” are drifting towards you (pun intended)

33 products containing 2,4-D and

32 products containing #dicamba
It just never ends. EPA has been in charge of pesticides 50 years. This is just two years’ worth of product approvals. Over these 2 years the # of pesticide products approved is nearly 600 per year!!

I’m not sure we need 600 pesticide products period, let alone each year
The U.S. is literally a dumping ground for toxic pesticides that many other countries won’t even touch and our regulating authority has seemingly no desire to change that…but it tries really hard to make you think it does

It’s just smoke and mirrors

The House Subcommittee on Economic and Consumer Policy just released an investigation into seresto that found the flea collar should be taken off the market

A lot of new info in the report that had not been reported on previously

I'll sum it up 🧵

investigatemidwest.org/2022/06/15/con…
Here’s the report. It takes you through the approval of the collar in 2012 to the present. It provides examples of EPA failing to stand up to an industry that feels so entitled, that even the mention of commonsense restrictions was met with derision

oversight.house.gov/sites/democrat…
We have a lot more detail of what EPA was seeing and saying – stuff that was redacted in our FOIA documents

Seresto had 163% more incidents labeled either “Death” or “Major” than the 2nd most dangerous product, and 428% more than the 3rd

As someone who is not opposed to genetic engineering but often at odds with how it is currently used in agriculture, I think we need more nuanced looks at GMOs in the media.

Instead we get this

nytimes.com/2021/07/20/mag…
In academia I genetically engineered non-pathogenic bacterial cells and human cells to better understand the genetic basis of chronic diseases like cancer. I understand how genetic engineering works and the promises it can hold, particularly in the biomedical field
It’s easy to find some small company that genuinely wants to better people’s nutrition through genetic engineering and use that as a poster child

But it's a disservice to not adequately explain “what is” instead of “what could be” in some fairytale world that does not exist

We’re in the middle of a public health crisis and the pesticide industry and USDA are working to weaken international guidance aimed at making sure lifesaving medicines still work in the future

How and why is the pesticide industry doing this? 👇

nytimes.com/2020/09/24/hea…
For starters, medically important antibiotics are used as pesticides to kill bacteria on crops. Fungicides, similar to antifungals used in humans, are also widely used as pesticides

The more you use them, the more likely it is that fungi or bacteria will become resistant
Increasingly, there is worry that the overuse of these medicines as pesticides can lead to antibiotic and antifungal resistance in human pathogens and cause these medicines to not work when our lives depend on it

There's a small bright spot in EPA’s atrazine re-approval

Thanks to a legal settlement by conservation groups, atrazine will be prohibited in Hawaii, Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands and the North Mariana Islands

biologicaldiversity.org/w/news/press-r…
This is an incredible conservation win as these places are biodiversity hotspots. Use of atrazine will also be prohibited along roadsides, in forests and on X-mas trees in the continental U.S.

The harm from atrazine’s re-approval is immeasurable, but these areas will be spared
This is being billed by the EPA and industry as “voluntary” measures they are taking, but there is nothing voluntary about this.

They had to do this as the absolute minimum step of beginning to come into compliance with the Endangered Species Act.

The ecological risk assessment for #chlorpyrifos was released today. The career scientists at EPA found that invertebrates could be exposed to more than 8,600-fold more than the level known to harm them

content.govdelivery.com/accounts/USAEP…
For mammals it's 1,900-fold more than the level known to cause harm. For birds it's 380-fold. For fish it's 160-fold.
The Fish and Wildlife Service found that #chlorpyrifos would put 1,400 endangered species at risk of extinction?

No wonder

I need to do something to stop stewing over the supreme court, so I'm just going to tell the story of how the endocrine disrupting pesticide #atrazine went from being on its last leg in the U.S. to being rubberstamped for the foreseeable future

biologicaldiversity.org/w/news/press-r…
No one is going to tell this story because there are a thousand other scandals happening right now and because it's super wonky.

Unlike a lot of the big environmental rollbacks that will hopefully be reversed after the election, this will likely fall under the radar
In 2016, under the Obama admin., EPA put out a devastating eco risk assessment of atrazine basically saying that its use has to be scaled back dramatically or there will be serious environmental consequences

In 50 years, this was the most hard-lined position EPA had taken
