Plastic straws are better, as are incandescent light bulbs.

The proof is in the pudding / free market. If the alternatives (paper straws, LED bulbs) were better, people would voluntarily buy them!

> To make their product, the food company’s scientists collect living cells from Pacific salmon and grow them in cell cultivators that mimic the inside of a wild fish—controlling factors like temperature, pH and nutrients, per their website. After harvesting them, the team incorporates plant-based ingredients to make the hunk of cells taste, feel and look like salmon fillets.

So... Like a wild fish, but with NO IMMUNE SYSTEM WHATSOEVER, which requires your sterilization protocols to be effectively perfect.

NASA has tried and failed to get their sterilization protocols to perfection levels for Mars landers, and consistently failed despite using basically zero organic materials.

We're going to cook this stuff, yes, sure (aren't we?)... but the squick is rational. And the problem gets inherently worse at larger scale production.

margalabargala•1h ago
No, not really, because the parent comment is freaking out about a problem that doesn't exist.

It's not going to be possible to grow a thing that looks like a piece of salmon but is secretly riddled with viruses and bacteria.

Either the lab gets their sterile technique right and they wind up with something that looks like salmon, or they get it wrong and you wind up with bacteria slop. Things that look like salmon can only become so if no bacteria and viruses are present.

mapt•1h ago
A fair point, but wouldn't it only become unrecognizable at levels that mean you're effectively eating pus instead of salmon? My understanding is that the effective innoculation needed to give botulism to a human baby (who has an immune system, just less of one than we do) is <100 spores, which is picograms.

There's just such a gulf between the prices at which this is feasible for food use, and the prices at which existing large bioreactors can culture animal tissue.

If we can't even get plant slop ("algal biodiesel") culture consistent and cheap enough to burn in an engine, or get plant slop ("tilapia feedstock algae") cheap enough to industrialize to outcompete chickens... I don't know that I'm comfortable eating bioreactor meat that can only survive in the FDA danger zone.

dekhn•1h ago
In the real world I don't think you'll find salmon that don't have bacteria and viruses (https://www.nature.com/articles/s41598-023-43345-x shows both "good" and "bad" bacteria and certainly many salmon are infected with a range of viruses (not sure if there are any "good" viral infections, but some are not fatal).

Don't forget that salmon and most other deep sea fish are immediately frozen when caught, which not only helps preserve flavor, but eliminates parasites (https://en.wikipedia.org/wiki/Diseases_and_parasites_in_salm...)

arrosenberg•1h ago
Can you explain why this situation is any different than regular meat? I.e. Fish immune systems don’t stop parasites from being present in the meat, flash freezing is what kills the parasites.
goda90•1h ago
This obviously varies by animal, but some meats are safe to eat raw or undercooked if the animal was healthy because the meat doesn't have lots of pathogens inside it. Flash freezing won't kill bacteria or viruses that the immune system of an animal might.
mapt•1h ago
Parasitic worms are huge, complex multicellular animals that co-evolved to sometimes survive the immune system response to their presence; Freezing kills them because they are huge and the scale of ice crystals severs important body parts. Living bacteria, living fungi, spores from these, viruses, and importantly heat-resistant toxins produced by these, are what I'm worried about.

One of modern humanity's oldest activities is fermenting carbohydrates in large bioreactors into alcohol, yogurt, and pickles, but there are a lot of things that turned out not to work in that history.

When we try to fabricate, say, monoclonal antibodies using large cultures of multicellular tissues for pharmaceutical work, the price ends up coming out to millions of dollars a kilogram.

I am implicitly skeptical of the protocols of a protein tissue culture that has to be produced at the ~$30/kg price level.

Could you eat it and not die? I'm sure!

But could you feed people with a billion meals worth of batches and have nobody die? I'm less sure! My understanding is that tissue culture failures are frequently the bane of a biologist's research program.

LeifCarrotson•56m ago
Fish immune systems sole reason for being is to stop parasites from being present in the meat while the fish is alive. They're literally swimming through a soup of arthropods, plankton, algae, bacteria, and viruses that would love nothing more to turn their meat into more of themselves. There's always a bigger fish that is trying to eat them, yes, but the smaller critters want to eat as well!

Freezing doesn't kill the parasites, it slows the clock that started ticking when the fish was killed. It's not pasteurization, like what's done to canned tuna. It just slows the clock when you refrigerate or freeze the fish, but does not reset it to zero. And of course, if you're eating fresh fish that was healthy when it was killed, there's no need for an intermediate freezing or pasteurizing step.

This situation is different because the "clock" starts when the cell cultures are removed from the donor salmon. The whole blob/tank/plate/catalyzing surface (I'm not sure what the design is, I wish they had more documentation) on which the product grows for the whole time that the product is growing is vulnerable to a single bacterium that would grow out of control, like an immunocompromised human might be killed by an ordinary illness that most people would shrug off in 24 hours.

dekhn•46m ago
Freezing (properly) is widely considered (by scientific establishment) to kill most parasites, not just slow them down.
mapt•41m ago
When biologists talk about parasites, they're talking about numerous organisms from multiple kingdoms in one of the widest ecological niches.

When the FDA talks about freezing killing parasites in fish, they're talking specifically about anisakis worms - https://en.wikipedia.org/wiki/Anisakis

Don't worry, if you catch any disease you can use any antibiotic that still works after spraying farmed salmon willy-nilly for years.
mapt•16m ago
Antibiotics only work on live bacteria, and only sometimes. "Any disease" is a much broader category.
fastball•1h ago
What? The requirements for this are nothing like what is required for sterilization of a Mars rover. NASA's goal is to not have a single iota of foreign organic material on rovers, which is obviously not even close to what is required here. The only thing you need to worry about with this stuff is whether there are any dangerous bacterium in it (e.g. salmonella), which can be readily monitored and avoided without herculean effort. And unlike real salmon, parasites and viruses won't have much opportunity to gain a foothold.
MostlyStable•1h ago
The lack of an immune system is not a health and safety risk, it's a business risk. An infected batch won't get served to humans it will just die/fail and need to be thrown out. Fighting infection is one of the reasons that lab-grown meats are so expensive. I have seen reasonably convincing technical analyses which claim that it would require pretty massive technological innovations (that are not anywhere on the horizon so far) to make any lab-grown meats economically viable. That's very likely the reason for the fact that (as pointed out in another comment), this is not pure salmon, it's salmon mixed with vegetable product. That was almost definitely a cost-saving measure.

My personal guess is that the first actually economically viable lab-grown meats will be of endangered/extinct animals that the extremely wealthy will be willing to pay the exorbitant costs that it takes to create them for the novelty factor.

mapt•37m ago
There are very likely degrees of infection which are not obviously spoiled, but which have health consequences if consumed. The locus at which the antibiotic/etc protocols are mostly but not entirely effective.

If they're actively pushing into the market, that means they're selling _something_ at maybe $30-$100/kg. Would you trust that something, knowing what you know of animal tissue bioreactors? Would you trust a restaurant serving thousands of meals of that something?

Surimi is not mostly fish, it is mostly soy, wheat, various starches. Fish (blended Alaskan pollock usually) is a minority of material in most packagings.

This came as a shock to me. The macronutrients don't lie, though. Fish is protein and a little fat, carb content is fractions of a gram, and these labels are telling me that there's more carbohydrate than protein.

The ingredient labels that the FDA allows, do find a way to lie. If you read a ten-ingredient label that says "Ingredients: Beef, wheat flour, corn flour, oats, textured vegetable protein, canola oil, vegetable oil, xanthan gum, carageenan, salt", and tell people that this is the highest-percentage ingredient to the lowest-percentage ingredient ordering, most people will assume it's >75% beef, but all the label is saying numerically is that it's >10% beef; If every other ingredient was in the 9.0 to 9.9% range then the beef input would be around sixth of the material. Add more ingredients and this can be manipulated even more.

I also don't think this is comparable. Blended Alaskan pollock had an immune system before it hit the cold chain.

derefr•48m ago
Look more closely. Here's their actual ingredients list (from https://www.wildtypefoods.com/faqs/why-are-there-other-ingre...):

> In addition to water and cell-cultivated salmon, our saku contains fats derived from canola, sunflower seeds, and algae, soy (an allergen), potato starch, konjac (a root vegetable), beta-carotene and lycopene (natural colors), carrageenan (an extract from red seaweed), and natural flavors.

Think about why each of these things are in there:

• Fats — because the parts [tissues] of the salmon that we eat, have not just muscle cells contained in them [the part that tastes + mouthfeels + cooks like salmon], but also fat cells (adipocytes), to contribute the taste + mouthfeel + cooking properties of "fatty tissue" [which is how we expect salmon to be] vs "lean tissue". And sure, the people creating this thing could have another tank growing "salmon-derived adipocytes", with some hormone bath to trick those adipocytes into absorbing and metabolizing nutrients from the environment to grow heavy with fat... but why bother? (That actually sounds dangerous, in fact — you might end up eating big doses of fish hormones trapped in the fat.) At the micro level, a little sphere of fat is a little sphere of fat; you can use a salmon adipocyte, some other kind of adipocyte, or even just a skin of sodium alginate, and the taste and texture of the result will be identical, as long as the fat inside the bag has identical properties (glyceride chain length, mostly).

• Natural colors and flavors — weirdly enough, because salmon grown on its own wouldn't look or taste fully like salmon. The look and flavor of salmon comes not just from what the salmon itself produces via the action of its cells/proteins/DNA, but also from "impurities" — things the salmon eats, that end up depositing into the salmon's tissues over time. Like how eating shrimp makes flamingos pink. Salmon without those things is white, and missing some of the sweetness we associate with salmon. (You can even notice this in salmon meat from different conditions; wild-caught salmon usually gets more of these nutrient sources than farmed salmon, so wild-caught salmon is often a much deeper reddish-pink color than the orange of farmed salmon.)

• Starch, maybe carrageenan (and the implicit ingredient, water) — together, a simulacrum of (slightly-viscous) salmon blood. Using water alone wouldn't work; it's too thin, it'd just run out of the muscle tissue like a water from a sponge, desiccating the tissue over a span of minutes. You need some thickener to prevent that. (I suppose you could make salmon blood plasma + platelets. Might be more nutritious if you did. Not sure how you'd get it into the tissue reliably, without any kind of circulatory system in there. And it probably doesn't make much of a difference to taste or texture even if you did. But this might still be a v2.0 goal of theirs.)

• Soy and konjac (and also maybe carrageenan here) — a simulacrum of connective tissue, i.e. collagen. This is likely the matrix holding the cells in place. There's no such thing as "cells stacked directly on other cells" that actually stays together; there needs to be some non-cellular tissue matrix that the cells slot into. (Compare/contrast: "meat glue." Is a chicken nugget chicken?)

Why not actual collagen as a matrix, or maybe, say, gelatin? Why not ground-up shrimp as a colorant instead of beta carotene + lycopene? Why vegetable oils instead of animal fats? In all these cases, probably because their goal with these ingredients seems to be to only build this salmon out of plants + cells, rather than any animal byproducts. An unstated premise here seems to be that they want to design the process such that no matter how far it gets scaled up, there's no point at which it would be more economical to switch one of the ingredient sources from "make it in a bioreactor" to "get it from an animal byproduct sources", and at even further scale, "drive animal slaughter to get said byproduct as the product."

AFAICT, this is almost the closest thing you will ever be able to get to something you can call "salmon" — or maybe more specifically, "animal-harm-free salmon" — that can be created solely in a lab.

(To get any closer, you'd need to get pretty mad-science-y. You could, in theory, genetically engineer a... tree, or what-have-you, that would metabolically synthesize the salmon blood plasma, the salmon connective tissue, the salmon-prey-species tissue trace impurities, etc.; and also act as a host to a commensal salmon cell population; eventually putting all that together inside a fruit or something. Pluck and peel the fruit, and inside — salmon muscle matrix tissue, fully cellularized, with solutes. [Though probably with the tree's vascularization, rather than salmon vascularization.] We're probably 50 years from understanding genetic engineering well enough to do that; and even then, it'd probably be operationally impractical, due to salmon muscle tissue rotting at any temperature a tree would grow at. But that product would technically be "closer to salmon", I guess.)

bowmessage•46m ago
> Why not actual collagen as a matrix, or maybe, say, gelatin? Why not ground-up shrimp as a colorant instead of beta carotent + lycopene? Why vegetable oils instead of animal fats?

Simple answer: they're cutting corners -- increasing shelf life, decreasing production costs, and overall increasing profits, like many of the big food corporations operating today.

lukevp•31m ago
The cost of the processes for these alternative meats astronomically outweighs the cost of ingredients, especially the cell culturing. It is unlikely that any of these companies are even making profit at this point. This is a long play to get the public to buy into this alternative food source, and only then will the scaling be enough to reasonably profit from any of this. There’s a baseline cost that they have to hit (farm raised salmon) and it’s incredibly cheap. Swapping out ingredients won’t make it cost competitive. Scaling up bioreactors might.
derefr•21m ago
I don't know about that.

Buying some filtered animal-derived blood plasma on the open market and letting the tissue grow/soak in it, would likely be a lot cheaper than precision mixing+dispersing of thickeners + reverse-pressure-gradient tissue impregnation of those thickeners. Food-grade blood plasma is the lowest-demand animal byproduct there is — it's what gets rejected out of even blood-sausage manufacture.

Same with collagen vs., specifically, carrageenan — collagen's cheap in bulk and works great for getting animal cells to stick to it; carrageenan's expensive, finicky to work with, and there are concerns about the carcinogenic effects of its long-term consumption. Many food-product manufacturers have moved away from previous formulations containing carrageenan; companies are only sticking with carrageenan at this point if there's nothing else that works within their constraints. Judging by other carrageenan-containing products, those constraints are probably something like "plant-derived; solid at room temperature; melts in your mouth; decent compressive strength, yet tears easily under tension."

And vegetable oils would be cheaper than animal fats... but vegetable oils with the same set of health guarantees as salmon (i.e. "omega-3 rich" vegetable oils) are not. And their product does claim to have the same health benefits as real salmon; so presumably they are aiming for that omega-3:omega-6 ratio target, since it's usually the headline "health benefit" of eating salmon. Which means they're probably buying, continuously-measuring, and mixing different oils to hit that ratio — similar to what orange-juice processors do to create a homogeneous juice.

We’ve worked hard to ensure that cultivated salmon cells are the first ingredient in our salmon saku (after water). After we harvest our cells, we integrate them with plant components to create the desired texture and flavor of a traditional salmon fillet.

In addition to water and cell-cultivated salmon, our saku contains fats derived from canola, sunflower seeds, and algae, soy (an allergen), potato starch, konjac (a root vegetable), beta-carotene and lycopene (natural colors), carrageenan (an extract from red seaweed), and natural flavors.

Hmm. They also compare their place to a microbrewery but I can't find any photos of the actual production process, generally a point of pride for a microbrewery. It sounds less like "lab grown meat" than literally "lab grown cells" + other stuff to mimic aspects of meat texture/flavor/color.

> CO2, food safety

I'm not 100% sure either of those has been proven out.

I could see CO2, but it sort of depends on how much power the bioreactor and sterilization consumes and how much methane is release. Granted, it'd be easier to capture those and easier to place these reactors in or near a grocery store, for example, for immediate delivery.

Food safety is almost certainly going to be a bigger problem. The big problem with bioreactors is they are cultivating the ideal substance for very nasty bacteria/fungus/etc to flourish in. Bioreactors do not have immune systems. That means keeping things absolutely sterile is of the utmost importance. I'm sure when the initial products are produced safety will be pristine. However, what happens when the CEOs of these companies decide to cut back? Heck, what happens when the new guy forgets to do a sterilization cycle or runs it short?

A major issue is these will be regulated by the FDA which has a history of doing a poor job of keeping food safe. I'd feel better if it were under the jurisdiction of the USDA.

Looking beyond just eating the output, encouraging research into bioreactors and effective sterilization is a great path towards lab grown organs for humans. Imagine a world where getting a heart transplant isn't a lottery anymore. This is a worthy path for research imho.

Imagine a world where you have to take whatever "heart" a pioneering lab can produce for under $100. Are you gonna be in the first group of recipients to risk it, knowing that these labs are largely unregulated startups?

I can cherish the research path and value the intended endpoint, but knowing what I know of agribusiness, early approval to market seems a mite reckless. Particularly in 2025. Particularly with "sushi-grade fish".

We produce millions of tons of affordable meat from industrial production of animals THAT HAVE immune systems, swimming in antibiotics, that the FDA tells you to cook thoroughly because it's definitely full of salmonella. We chop it up using child labor on production lines that would make you a vegetarian if you saw them.

Unfortunately the alternative for not using a lab grown heart in that scenario would be death, not a human heart. So I’m guessing many people will take it.

You bring up a good point, a future steak factory will be a lot more centralized than the distributed system of farms we have today. So an outbreak in one would significantly disrupt the market, at a minimum, and in the worst case cause a mass outbreak. The flip side is that a factory has a higher ceiling for cleanliness and disease surveillance. I would be wary of foreign lab grown meat for this reason.

Their first additive after water and salmon cells is canola derived so any environmental or food safety claims should factor that in.

Canola is often sprayed with neonicotinoids and the oil processed with solvents like hexane.

I'd personally prefer to get my omega acids from real salmon.

I'm already picky with processed food. This takes the cake on the highest form of processed available.

Hard no from me, not even once.

There’s a whole industry for cell-cultivated meat since the FDA approved it a few years ago.

Salmon is just one example.
