“Cell culture media ingredients can be sourced in a variety of ways. The US Davis authors assume in their study that media ingredients would be produced and purified on an individual basis, as in the pharmaceutical industry,” ​noted the GFI.

But if the cultivated meat industry were to pursue this method of sourcing and purifying media inputs, the costs would likely be too high for the vast majority of products to be competitive with conventional meat, we were told. “As the UC Davis study demonstrates, it also comes at a high environmental cost. So it wouldn’t make economic or environmental sense for cultivated meat to take this method forward. Nor would it be necessary.”
