Screwworms in US: Human risk is low—but they can burrow through your skull

Classic Dr. Mole article, complete with horrific (thankfully linked and forewarned) imagery.

Given how terrible screwworm is, it saddens me that we weren't able to hold the line against them at the Darien Gap. I assume a drop in funding resulted in fewer sterile flies released, and allowed them to return.

I've always thought that sterilization like this was always a neat strategy. But, I'm reminded of the quote: "You're implying that a group composed entirely of female animals will breed?"

Then I'm like wait "Life finds a way". How long before we have sperm dependent Parthenogenesis a-la Poecilia Formosa?

So DOGE defunded USAID programs for monitoring and containing screwworms in Central America. I'm sure this outbreak is just a coincidence though.
Well to be fair in this case, it appears the collapse of the "front line" at the Darien Gap happened in 2022, so a link to Covid-related disruption is possible. But perhaps a look at year by year funding of the barrier project would provide more clues.

An issue with control strategies is that they exert massive evolutionary pressure on the target species. You can see this in human timescales with bacterial antibiotic resistance.

If you don't continuously adapt your techniques, then it's just a matter of time until you see insects resistant to the sterility technique, whether via parthenogenesis, promiscuity, rigorous sexual selection, or some other strategy. That's why ongoing research is important even if the problem is "solved".

Covid killed +750,000 Americans under Trump.
Measles killed a dozen and infected hundreds in schools, under Trump.
Polio now is back, under Trump.
HIV research and treatments threatened, under Trump.
Ebola back in full swing, due to USAID cuts, under Trump.
Hantavirus treatments in jeopardy, under Trump.
NIH and other medical researchers canned by Trump.
Global infectious diseases now up, thanks to Trump administration reckless cutting budgets to waste money on a ball room, UFC ring, ridiculous arch, and more waste and grift.

I believe the containment breach happened before DOGE cuts (happened in 2025) and Mr Trump cancelled the ban of livestock crossing the US/Mexico border shortly before DOGE cut the program.

I'm sure we'll get a press conference with RFK Jr. eating a bowl of screwfly larvae saying that they're healthy and nutritious.
Do you think he will have 'screw worm' parties to help people get it so they can build a natural immunity to them - you know, like people would have covid parties...

Oh it is worse than that.

US beef is highly undesirable internationally, and has been for 30-ish significant years. Why? Remember that Mad Cow scare? Yea well, the "F" in FDA is joked by FDA workers as being silent--as things like cattle herds and turnover are more or less untracked by regulators. Which makes tracking things like screwworms or Mad Cow a spilt milk problem as soon as it is found. Cattle ranching in the USA is an industrial-scale activity, and actually screening for these ailments, given the herd turnover and national movement and international-import of cattle, into the US as stock makes it nigh on impossible.

Which is why after Mad Cow US beef took a nose dive. You can't trust the quality or that it is bug-free. TypeAshton did a vid on it last year:

My friend who is a veterinarian predicted that we'd start seeing cases in dogs - but she thought we'd have a few more months.

This is really horrific. Regular flies can cause flystrike in livestock which is pretty horrible, but usually those wounds have to be pretty big. (They can hide under wool, feathers, or just because herds of cattle roam unsupervised.) Tiny wounds on the scalp, bug bites? Eeesh, there's no way to notice those kinds of tiny opportunities on yourself or your pets.

The one tiny thing I can hope for is that Texans will start reconsidering their political choices and relationships with government when their pets are impacted. Good government exists to keep our lives comfortably boring - and like cybersecurity, it can be hard to convey the value of Things That Didn't Happen because someone was working hard in the background.

"Insects restaurant"? I think your auto-correct made a poor choice on your behalf. Resistant presumably.

The containment breach was noticed in 2022 yes, and was likely the result of various covid-related disruptions and exceptions, both getting sterile flies deployed and also less control over the movement of livestock. (One might point out that priorities and choices made during the first Trump Administration are likely highly contributory.)

DOGE cuts on top of an already alarming situation were just the perfect example of the cluelessness and shortsightedness of how the Trump administration approaches literally everything. Haw haw haw why we pay for sterile flies in Panama and Mexico? Obvs the dumbs.

And less than a week ago Brooke Rollins, head of the USDA, was saying Everything Was Fine.

I can tell you among my veterinarian friends, they've been incredibly concerned for months. Anyone with any expertise in the area knew this was a very big deal.

I think everyone with a degree in medicine has been tearing their hair out over the last year and a half. My PCP was eyes-glazed at the vaccine decisions last year and it hasn't gotten better,
