When lab-cultured "meat" production first began, companies depended on fetal bovine serum (FBS) as a growth medium. Producing FBS involves extracting blood from the fetus of a pregnant cow when the cow is slaughtered. Given its high cost, it appears that FBS is usually only used during small-scale lab trials.Does lab-grown meat have blood?
In reality, it turns out that many lab-grown meat products actually contain a shocking amount of blood. More specifically, they often rely on fetal bovine serum (FBS), or blood taken from unborn cow fetuses, Mother Jones reports.
What does lab-grown meat contain?

Why is lab-grown meat not good?
Health concerns of lab-grown meat
One potential health concern that stands out is the cancer-promoting properties of cells that proliferate exponentially in vitro. Consuming lab-grown meat with such faulty cell lines may have unwarranted effects on the human body, the exact effects remain unknown.
What is fetal cow blood used for?
FBS is the liquid portion that remains after blood is drawn from bovine fetus coagulates. It's the most widely used serum supplement for in-vitro cell culture (for eukaryotic cells). Additionally, it plays a vital role in the research of human and veterinary vaccines and has applications in stem cell research.
The Truth About Lab-Grown Meat
Why are pregnant cows sent to slaughter?
This practice, which is legal, is apparently due to financial reasons, since a pregnant cow weighs more and will therefore be sold for a higher price.
What is bovine blood?
Bovine blood is made up of 80.9% water, 17.3% protein, 0.23% fat, 0.07% carbohydrate, and 0.62% minerals (Alencar, 1983). Blood composition is similar to meat composition except for the iron (36.3 mg/100 g of blood), which is ∼10 times the concentration in meat (Wismer-Pedersen, 1979; Alencar, 1983).
Would vegetarians eat lab-grown meat?
By definition, a vegan diet does not include consuming meat or any form of animal products. For this reason, lab-grown meat would not be considered vegan because the ingredients needed to produce the synthetic meat are all derived from animals.
What are the pros and cons of lab meat?
Pros
- It is more sustainable. There is no doubt that lab grown meat is a more sustainable solution. ...
- The animals suffer less (or not at all) ...
- It has less bacteria. ...
- We are many years from producing large quantities. ...
- It is very expensive to produce. ...
- We don't know how to regulate it.
Does lab-grown meat taste different?
Because lab-grown meat is meat, it should theoretically share the same taste and texture as conventional meat, if formulated correctly. The only difference is the process by which the quantity of meat 'expands'.
What are the disadvantages of lab-grown meat?
The Downsides of Lab-Grown Meat
Animal agriculture accounts for more than 14% of global GHG emissions caused by human activity, but lab-grown meat may, in fact, worsen climate change. Although it's expected to produce more CO2 than the more potent methane, CO2 takes much longer to dissipate.
How soon will we be eating lab-grown meat?
Lab-grown meat could make strides in 2022 as start-ups push for U.S. approval. Cultivated meats are real animal products made in a lab. Regulators in Singapore approved cultivated chicken for sale in 2020, while the FDA and USDA are considering it in the U.S.
Is lab-grown meat ethical?
Cultured meat avoids many of the environmental harms of conventional livestock (although to what extent remains contested) and requires none of the harm to animals of traditionally-sourced meat.
Does Beyond meat use animal blood?
Yep, the Impossible Burger and Beyond Meat Burger are both vegan -- neither contains any animal products of by-products. In a statement to CNET, Impossible Foods confirmed that its burger is vegan but noted it has used animal testing to evaluate the safety of its heme protein (also called soy leghemoglobin).
What is 3D printed meat made of?
Recently, Israeli bioprinting company MeaTech 3D Ltd announced that it succeeded in printing a 104 gram (3.67 oz) cultivated steak using their proprietary 3D printing technology. Made of real cultivated fat and muscle cells, the steak is believed to be the largest cultured steak produced to date.
Does lab-grown meat have a future?
“New studies show cultivated meat can have massive environmental benefits and be cost-competitive by 2030,” it trumpeted, suggesting that a new era of cheap, accessible cultured protein is rapidly approaching. The finding is critical for GFI and its allies.
What is your opinion on lab-grown meat?
Lab-grown meat not only addresses issues of animal cruelty, sustainability, and food security, it is also clean — free of antibiotics and harmful microbials. Nevertheless, to call a spade a spade, lab-grown meat is still very much animal meat and therefore not suitable for vegans and vegetarians.
Do vegans support lab meat?
Lab-grown meat could be a solution that benefits everyone. No animals are killed in the process, we vegans will love that. Meat eaters don't have to radically change their diet just yet, they will be happy with that. The environment benefits significantly, we will all love that.

Is Lab Meat Vegan? Lab-grown meat is meat, meaning it is not vegan. However, the concept may create a “loophole” for some due to the fact that it can be made without the slaughter of animals. Not all lab-grown meat production is free from animal use.
Are stem cells vegan?
However, other animals and animal products are necessary in order to make lab-grown meat, namely stem cells and fetal serum. This means that while lab-grown meat has the potential to save lots of animal lives, it is by no means vegetarian or vegan and definitely not cruelty-free.
What animals blood is closest to humans?
Studies have shown that pigs are the best candidates for xenotransfusions, with porcine blood having more similar characteristics to human blood than blood from other animals. “The size of red blood cells is similar,” writes David Warmflash of the Genetic Literacy Project.
What does fetal calf serum contain?
There are 1000+ components found in FBS, including proteins, electrolytes, lipids, carbohydrates, hormones, enzymes, and other undefined constituents, which are necessary in many culture conditions to support cell growth.
How do they extract fetal bovine serum?
Fetal bovine serum (FBS) is a common component of animal cell culture media. It is harvested from bovine fetuses taken from pregnant cows during slaughter. FBS is commonly harvested by means of a cardiac puncture without any form of anaesthesia.
Can you eat a cow fetus?
Slink veal is made from stillborn calves, or unborn calves taken from slaughtered pregnant cows. It's illegal in the US and Canada.
