Here is the process for making lab meat. Let me know if it sounds healthy or humane to you…
How Biotech Grows Meat in Labs
To make fake meat, cell lines are taken from a living organism. They’re then manipulated to grow quickly and consistently. "What are cells that proliferate quickly? Either cancers or fetuses. They have cells that proliferate very quickly," van Hamelen says.4 For lab- grown meats, biotech is cryptic about what types of cell lines are actually used.
Normally, cells grow in a structure in your body. The cell lines being grown in bioreactors in labs are grown in a thin film or growth medium. In the body, the growth medium is your blood, van Hamelen explains, a complex substance that laboratories try to replicate using fetal bovine serum (FBS) — blood taken from living calf fetuses.
"It’s really gruesome how this is harvested," she says,5 pointing out that this negates the narrative that lab-grown meats are made without animals. FBS is often used to grow cultured cells because of the proteins and vitamins it contains. A 2013 study stated, "In many common culture media, the sole source of micronutrients is fetal bovine serum (FBS) ..."6
When lab-grown chicken made by U.S. startup Eat Just debuted in Singapore in 2020 — marking the first cultured meat to be sold at a restaurant7 — it was produced using FBS.
In order to develop synthetic "blood" instead, precision fermentation, using genetically engineered microbes, is used, along with artificial hormones, which can’t legally be added to food in the European Union. Micronutrients and minerals must also be sourced, making the process "insanely expensive," van Hamelen says.8
If I find any peer reviewed studies, I’ll link them. At this point the FDA doesn’t seem to care about safety checks or peer reviews
