A nugget of life

In the summer of 2013, I blogged about meat that is grown in labs and bioreactors, which are essentially the prototypes of the factories of the future.  I wrote then: "It is only a matter of time before we perfect such techniques and produce beef or other animal foods without the animals."

It is not that I am a cave-dwelling carnivore.  Far from that.  As with any other development, this too fascinated me.  It interested me so much that I wove this news item into appropriate contexts in my introductory classes.  Student response was typically and overwhelmingly one-sided--meat that doesn't come from killed animals but is produced in factories is unnatural.

I would then nod along, and ask them if they eat pasta.  Of course they did.  "Isn't pasta produced in factories?  Have any of you tried making pasta?"

Once--and only once--a young woman's hand went up.  "Sometimes I make pasta with my grandmother," she said.  And then added that it was a lot of work.

My point was this: If students eat "factory-produced" pasta and hot dogs and whatever else, why should they view the lab-grown meat any differently.

I love this Socratic tradition, which I might not get to practice for too long though.

Seven years after that blog post, the world is now getting closer to making cultured-meat a reality in the marketplace.

The first lab-grown, or cultured, meat product has been given the green light to be sold for human consumption. In the landmark approval, regulators in Singapore granted Just, a San Francisco–based startup, the right to sell cultured chicken—in the form of chicken nuggets—to the public.

Just had been working with the regulators for the past two years and was formally granted approval on November 26.

You need a reminder on how this meat is produced?

Most cultured meat is made in a similar way. Cells are taken from an animal, often via a biopsy or from an established animal cell line. These cells are then fed a nutrient broth and placed in a bioreactor, where they multiply until there are enough to harvest for use in meatballs or nuggets.

There is no killing involved. "The cells for Eat Just’s product are grown in a 1,200-litre bioreactor and then combined with plant-based ingredients."   The fact that there is no killing involved makes all the difference to many millions. 

Of course, the killing is not the only issue, which is why there are many firms in the race:

Dozens of firms are developing cultivated chicken, beef and pork, with a view to slashing the impact of industrial livestock production on the climate and nature crises, as well as providing cleaner, drug-free and cruelty-free meat. Currently, about 130 million chickens are slaughtered every day for meat, and 4 million pigs. By weight, 60% of the mammals on earth are livestock, 36% are humans and only 4% are wild.

For now, as with any innovation, the costs are high, and the process is energy-intensive.  But, again as with most technologies, scaling will rapidly decrease costs and the demand for energy.

At some point, the US-based research/entrepreneur will go global--that's the plan

"We didn't work two years to get the approval just to sit on this," says Tetrick. "After Singapore we'll move to the US and Western Europe." But US availability won't be that simple: A regulatory process for cultured meat doesn't yet exist between the USDA and FDA

I imagine that tRump, who famously eats steak with ketchup, would have freaked out with this news story!

There are interesting parallels between the cultured meat and electric car sectors: Both are introducing a technology that can inspire initial resistance from consumers and existential alarm from conventional producers, both involve a major shift in infrastructure, and both need some degree of regulatory air cover to succeed.

It has been a long, long way from the African Savanna, and there is no going back.
