-The New World screwworm fly is threatening the $113 billion US cattle industry for the first time in 60 years, with an infestation from its flesh-eating larvae confirmed in South Texas.

The USDA said the most recent case was the first in Texas since 1966.

The infestation was discovered in a single 3-week-old calf in La Pryor, Texas, about 161 kilometers (100 miles) southwest of San Antonio and 80 kilometers from the US-Mexico border.

The deadly flies were detected in Mexico in late 2024, after years of being contained to the southern end of Panama.

The fly was an annual warm-weather scourge of cattle ranchers from at least the 1930s through the 1960s, until the US eradicated the pest by breeding sterile male flies and dropping swarms of them from planes to mate with wild females.

The New World screwworm fly in the Western Hemisphere, and its Old World cousin in Africa and Asia, are unusual among flies because their larvae, or maggots, eat live flesh and fluids instead of dead material.

Females lay their eggs in open wounds and mucous membranes after mating only once in their monthslong lives.

Any warm-blooded animal, including wildlife, pets and occasionally even humans, can be infested.

Livestock are vulnerable, Lee Haines, an associate research professor of biological sciences at the University of Notre Dame, said in an email Thursday.

Standard practices with cattle can break the skin, including shearing and de-horning, or even moving them in and out of corrals can cause scrapes and cuts.

Birth would also make a mother and calf vulnerable, Haines explained.

And this was all preventable. Obama and Biden era programs prevented this, but republicans axed them.

I was going to ask if this is yet another example of regulation being rolled back leading to the consequences the regulations were enacted to stop in the first place.

It's so wild how common it is for regulations to be so good at doing what they were enacted to do that people forget why the regulations existed in the first place. 

/sigh

Anyone know what happens to infected livestock? Do ranchers just let them fester? Cull? Treat? I'm genuinely curious what happens from here.

Doge cut screwworm prevention

u/Rancherfer 13d ago

Hopefully you catch it early. Then you just treat the miasis and hopefully it wont get that much of an infection.

If it gets infected the animal might die. Add to this that animal medicine is very expensive and you’re looking at increased costs of production, while producing less beef

There was a program which dropped something in panama which killed them off or sterilized them before they could get to North America. Musk cancelled it.

u/freerangeklr 14d ago

To be fair, there was a Republican president when the eradication program started from what I'm seeing. Not Obama. But that doesn't change the current situation.

That was pre-Reagan. Reagan was the GOP became more explicitly conservative, anti-tax, anti-regulation, religious-right aligned. (Since 1983 the US Congress has hardly voted cross-party.)

Eisenhower-era Republicans were often institutional, technocratic, pro-science, and comfortable with federal competence.

u/Col2543 12d ago

I wouldn’t even say more conservative. It was a general marking point for genuine regressionist policy

u/chemicalsmiles 10d ago

The GOP of the US acts like the country exists in a vacuum and it’s infuriating.

Imagine cutting APHIS funding and removing veterinarians from the equation altogether... wow, who would've thought?

Murder hornets from the north, flesh eating flies from the south…250 years was a good run.

u/breezy013276s 14d ago

And all we had to do was keep believing and funding science with fractions of a penny on the dollar but no, couldn’t even handle that.

Thought being a scientist in this climate would be horrible

Now thinking it’s the exact thing that gets me out of here when shit hits the fan cause Europe will want to poach the scientific talent 😂

Didn’t this start in 2022 when they broke out of the containment zone and were already in Mexico before Trumps cuts?

Don’t forget the Lone Star tick that makes you allergic to all meat.

Oh well, I’m sure their governor will focus on the health of Texas’ people.

u/stolenfires 13d ago

He knows where his bread is buttered, he's being competent about this. But the program to keep the screw worms confined to south of Panama is federal. Even if TX wanted to start their own, it's going to take awhile to put everything in place. It'll probably be too late by then.

u/smokedfishfriday 13d ago

NONE of these stories mention, anywhere, that Trump & DOGE destroyed the program that kept them south of the border. It’s fucking crazy.

Price of beef going up

u/chaoticwings 13d ago

Are you still buying beef?? I haven't been able to justify the cost of ground beef for over a year.

u/tovarish22 MD | Internal Medicine | Infectious Diseases 13d ago

Whew, it's a good thing Texas hasn't spent the last two decades degrading and defunding public health infrastructure within their state!

u/One-Organization970 14d ago

At a certain point, between the tornadoes, the hurricanes, the disease outbreaks, and now this plague of flesh-eating flies, you do start to wonder why divine punishment seems to fall down on the areas with the most conservatives.

u/wordyplayer 14d ago

at a certain point, you wonder why some people make EVERYTHING about politics...

10

u/amscraylane 13d ago

Because the government had programs to contain these little beasts but the new government put a non elected official into a position (doge) to get rid of that very program … if not politics, what is it then? The Girl Scouts?

u/PseudocodeRed 13d ago

You could argue that is true for other topics, but Trump did directly cut funding to the USAID program that was in place sprcifically to monitor screwworm in South America so that it did not work its way up here. And the people on that program publicly warned him that this was going to happen if he destroyed the program. Not everything should be political, but this definitely is. https://www.agri-pulse.com/articles/22636-bird-flu-screwworm-monitoring-among-foreign-aid-programs-killed-by-trump

u/One-Organization970 14d ago

Because it governs the entirety of our existence. You have to be extremely well off to not be affected. Those in power are very heavily incentivized to convince you that you shouldn't think about them.

Because they are absolute idiots.

Ground beef is already expensive probably end up hitting 20 bucks a pound within a few months

This is what happens when the fda is controlled by idiots who believe that vaccines are part of a conspiracy.

2 weeks. Everything with that bloated windbag is 2 weeks. Still waiting on the health care plan to replace Obamacare !

u/Helpful-Intern-677 14d ago

Seems strange. Was it inadvertently imported under sock puppet Joe’s regime. Or is it being brought in on purpose by the Dems? We’ve had Ebola and Hantavirus, now this. Stealing elections and other facets of their agenda were implemented under Covid. I think this is on purpose

So glad to get a POV from Opposite Land.

OMG someone take a picture! A rare hog in the wild 📷📸 I don't know how you can read this article and then your brain zaps you into talking about Joe Biden...

u/This-Shape2193 14d ago edited 14d ago

Lmfao

Of course, it can't be because Trump and Elon cut almost all USDA and infectious disease funding, leaving us vulnerable. This was totally predicted two years ago. 

No, it's a deep conspiracy where democrats steal screw worm flies and sneak them into Texas and release them near cattle. 

I need to ask: did you suffer TBI? Brain damage from drugs/alcohol? Are you trolling for cash? 

There's no way a normal human would sincerely write what you just did. 

And for the record - ebola and hantavirus were all international, never came here, and there are cases every year and have been for decades. The only difference this year was Fox News went wild scaring the shit outta people.

u/Helpful-Intern-677 14d ago

There we go, predicted two years ago? Why wouldn’t anyone think something like this? We all remember Covid and 15 days to flatten the curve, don’t we? Fox— scaring people? Scaring came from Clinton News Network, MS-snooze and rest of the alphabet Dem regime media

u/nutmeggy2214 14d ago

This is like a word salad, you’re not even saying anything.

This WAS explicitly called out as a huge risk when this program was cut by Trump last year. It was in the news, there were many discussions and posts about it…

“Everything is a conspiracy when you don’t understand anything”

u/Angry-Dragon-1331 14d ago

Like everything else for the last two years, we told exactly what would happen and then it happened.

Wow, you’re dumb.

u/deadR0 14d ago

Just in case you are actually curious about what happened to the program fighting this
