Meat from a lab? Startups cook up alternative to slaughter

Memphis Meats, based in Emeryville, California, is one of a growing number of startups worldwide that are making cell-based or cultured meat. They want to offer an alternative to traditional meat production that they say is damaging the environment and causing unnecessary harm to animals, but they are far from becoming mainstream and face pushback from livestock producers.

"You are ultimately going to continue the choice of eating meat for many generations to come without putting undue stress on the planet," said Valeti, a former cardiologist who co-founded Memphis Meats in 2015 after seeing the power of stem cells to treat disease.

The company, which also has produced cell-grown beef and duck, has attracted investments from food giants Cargill and Tyson Foods as well as billionaires Richard Branson and Bill Gates.

A report released in June by consulting firm A.T. Kearney predicts that by 2040, cultured meat will make up 35 percent of meat consumed worldwide, while plant-based alternatives will compose 25 percent.

"The large-scale livestock industry is viewed by many as an unnecessary evil," the report says. "With the advantages of novel vegan meat replacements and cultured meat over conventionally produced meat, it is only a matter of time before meat replacements capture a substantial market share."

But first cultured meat must overcome significant challenges, including bringing down the exorbitant cost of production, showing regulators it's safe and enticing consumers to take a bite.
