This might explain how wild deer develop prion diseases. My understanding is that they aren't eating the nervous tissues of other animals but perhaps an insect, parasite, or other lifeform is providing the infection.

Develop...maybe. CWD can stay dormant in soil for a long time (2+ years). https://dwr.virginia.gov/wildlife/diseases/cwd/what-are-prio...

Deer getting CWD from the soil wouldn't be unprecedented. Sheep get anthrax that way. Animals that keep their head down eating stuff off the ground are particularly susceptible to soil-borne infections.

Books have paragraphs, which are newlines and indentations, specifically to help people read in the face of what would otherwise be a wall of text. Being able to read large chunks of text with minimal or no formatting is useful, but so is knowing how to format the text you produce so it's easier for people to consume. We should all strive to be capable of both.

Most books paragraphs are larger than an HN comment without spacing. Since the ability to read books is crucial, it is better to exercise the skill of reading text without spacing than asking commenters to add them.

Books have an incentive to minimize whitespace, as it costs money (paper). Computer screens don't have this limitation so the cost: benefit calculation is different.

I thought the generally accepted science was that humans can learn disgust reactions socially, so that they are more adaptable on a non-evolutionary timescale. > The disgust system is a psychological mechanism for producing pathogen avoidant behaviour [10–12]. In previous work, we have stressed the universality of disgust, showing that there is much that is similar about disgust responses between animals and humans,…

How does this invalidate the point? The people who are using their brain to override their disgust system are probably doing something that's extremely maladaptive.

It invalidates it because you're saying disgust is evolutionary. The response is saying it's largely cultural, thus something that triggers disgust is not going against some "evolutionary truth" but is rather just another learned behavior.

If insects were such a valuable and risk free source of nutrition wouldn't we see a lot more human cultures eating them? They've been around forever, but somehow we share a mostly common disgust for eating bugs. Is it farfetched to assume that perhaps that disgust allowed us to survive.

That's simply not true. The UN FAO estimates that 2B people worldwide consume terrestrial insects regularly in their diets. Add in aquatic insects like shrimp or lobster and that number increases drastically.

2B people intentionally consume terrestrial insects.

99+% of humans incidentally consume terrestrial insects. Food processing is imperfect and insect contaminants are common.

"But the FDA allows up to 225 insect fragments per 225 grams of macaroni (yes, that's one piece of bug per gram) and 4.5 rodent hairs per 225 grams. Per 100 grams, the FDA allows either 10 fly eggs, five fly eggs and one maggot, or two maggots in most tomato products."

With the right conditioning, people can be made to accept all manner of madness.

The rejection of things can be "madness" too. We know that plenty of "natural" phobias are actually cultural, i.e. learned behavior. Toddlers and even infants pick up on social cues and develop fear and disgust responses by mimicking the behavior of adults and older children. "Conditioning" is an unnecessarily spooky framing for what is quintessentially "culture". My toddler's first reaction to ground pepper was to c…

Some aversions are cultural, others aren't. Which are which?

The fact that bug eating remains niche around the world, generally only seen in regions with a recent history of food insecurity, suggests that the conditioned madness is eating bugs, not aversion to bugs.

Cultural issues are as real as any other issues... Isn't it much easier to make an easy neutral change to your writing that will be positive for some readers than to assert their culture should learn to read better?

Following your reasoning we should all do efforts to translate all the documentation of all the software available in many languages, a major amount of work, instead of asking developers to learn English. And learning English is a major undertake compared to read comments without spacing.

I'm making a pragmatic argument, not a moral one. Adding spacing is easy and it helps more people enjoy your hard work. That's why you should do it.

I believe that improving accessibility of most knowledge through localization is a good thing.

There's the racial component as well. For instance Spaniards (ethnic Visigoths) have near-total immunity to bad pork, whereas Jews (Jewish Diaspora, ethnic Jews) are very vulnerable. Think of it this way: if there was a public service announcement by the early Jews, where would they write it down?

What do you mean immunity to bad pork?

Like eating pork that wasn't cooked very well, no problem. Or bad quality pork, perhaps.

In America it's irrelevant, the bacon is pre-cooked to high standards and comes from good sources. Partly because secular Jews eat that pork having no cultural norms around it, just driven by it being forbidden. They're vulnerable.

It's genetic, just like a certain tribe of Pacific Islander developed a partial immunity to prions, because they sometimes ate human central nervous system. It's genetic.

Survival of the fittest.

The importance of this subject is underestimated and applies as well quite independently of whether humans eat the insects directly or not. Consider the cuban tree frog for example, which has long since initiated its campaign in Florida to host and spread throughout the food chain the rat lungworm nematode. Rat lungworm (angiostrongylus) holds its own in the burgeoning presence of hideous and hostile parasites. It is…

So, reading this is intimidating. Can you ELI5 what risk these pose to humans or species in close proximity to us?

>ELI5

Hmm. That would come with the more frightening risk of HN community scrutiny, a sort of indelible scabies of the retrospective consciousness. What the hell..

If you're 5, or any age with a palate for insects, especially centipedes [1], cook them first or consider sugar free gummy worms until mom can prepare them properly.

More seriously, it depends largely on behavior, ie personal hygiene, industrial standards, awareness, etc. Some factors are potentially impossible to control, such as invasive species or other environmental factors.

There are older reports similar to [1] where children initiated the infection (of lungworm and other deleterious parasites) by consuming insects, and in some cases spread them to adults. There are many cases of vegetables infecting people too, eg lungworm in Hawaii [2]. Also many other species in man..most other countries.

In one study I read, a large and eclectic sample of vegetables and fruits from scattered European countries showed a high prevalence of infectious parasites in a significant percentage of the batch. Similar studies showed similar and worse elsewhere. One particularly interesting study found a vegetable farm which was frequently down wind of a kennel housing a large number of x (I've forgotten the animal type). The crop was riddled with wind-disseminated infectious parasites -- I forget the type, but it was nasty and somewhat impervious to the elements.

Invasive species, interference with wildlife, development, animal agriculture proximal to veg ag, climate and much more is involved. For anyone who realizes it as a formidable danger, I think the risk is smaller. For most, it's probably not large, but growing and, I personally believe, an insidious factor behind some misdiagnosed conditions.

Parasites are everywhere, with most posing minimal risk. Pinworms, for example, infect a surprising portion of the mighty and developed US population, which is why you can find pinworm medicine on the shelves of any pharmacy. They often go unnoticed, but in some, cause severe itching and further complications if untreated over many years. Children are common carriers and the eggs can be spread on/via dust particles that enter the nose, and by the very fingers that scratch the itch. Thankfully, a single dose of parantel pamoate and a thorough housecleaning usually eradicates the problem.

If you do vist Florida, which has been ill-advised by my HN editor[3], watch what you eat raw. Raw panther would be a great way to get trichinosis, with +20% of them carrying it. Wild hogs too, which is often where the panthers get it. Whether in Florida or Florence, raw foods pose risk, which sucks because they can also be the healthiest.

Indoor/outdoor pets are a difficult situation too. There are more and less serious threats here. I remember finding my best friend with little grains of rice crawling all over his arse. They are a form of tapeworm where fleas are the vector. Oddly, I could have eaten one if I so chose and have remained unaffected. However, if I'd eaten an infected flea, I'd be infected. The progottids of that particular species generally need to be ingested while inside the flea for it to settle in a new host. Edit: If the cat had laid in or passed over infected raccoon droppings, things could be much worse (think baylisascaris p). The mentioned tapeworms were easily eradicated with a single dose. Nothing works well on the former.

Most American health professionals will dismiss the risk of parasites as trivial, if that is any consolation. But if you prefer to pursue your concern, there is much to read and learn, from entertaining videos of people examining live worms in their restaurant sushi or wriggling through the salmon at Costco, to hard scientific studies and case reports of human and animal infections of many varieties everywhere in the world.

If I've failed to ELI5 or convoluted the subject, it's because it's a huge subject and I'm a mnemonically challenged dilettante with one finger to communicate with today. My advice is to not panic, don't develop complexes, and instead, be aware and learn and apply what you learn practically. And to be extra safe, avoid Florida -- it's getting crowded anyway.
