Cockroach¹ Milk: Yes. You Read That Right

SCOTT SIMON, HOST:

Is there a time in the future when the voice of a barista might ring out, latte with cockroach milk? Pour a cup of coffee while we tell you about the female Pacific beetle² cockroach. She does not lay eggs like most insects. She gives birth to live babies.

BARBARA STAY: It's a delightful³ little cockroach, not the kind that runs in sewers⁴ and is a pest in kitchens and bakeries.

SIMON: That's Barbara Stay. She was working in a lab at the University of Iowa when she discovered that Pacific cockroach beetle embryos⁵ take in food from their mother.

STAY: What they were drinking that was being produced by the food sack - by the uterus, essentially⁶, of the mother - was a liquid substances that they were sucking in. But in the gut⁷, crystals formed. And so it was after I discovered they were drinking it that I saw these crystals in the gut.

SIMON: Another researcher, Professor Subramanian Ramaswamy in Bangalore, India, took a closer look at those crystals.

SUBRAMANIAN RAMASWAMY: It turns out that weight by weight, this is three times more calorific value than, say, buffalo⁸ milk.

SIMON: That's three times richer in calories than buffalo milk. One scientist apparently⁹ took a taste of the yellowish substance and found it tasted like nothing. So you could, in theory, splash it into coffee or pour it over cornflakes. So could a competitive health food market that already stocks cow, goat, almond, soy, cashew, hemp¹⁰, rice and coconut¹¹ milk now see cockroach milk as the next superfood?

RAMASWAMY: In principle, it's a protein coming from a living organism, so in principle it should be fine. But today, there is no evidence that it is actually safe for human consumption.

SIMON: What a relief. Cockroaches¹² must be hard to milk anyway.
