Nestlé said in a statement on Thursday that it has developed a new line of pet food — Purina Beyond Nature’s Protein — that uses insect protein, millet and fava beans. One of the new recipes mixes black soldier fly larva, chicken, and fava beans; a second includes chicken, pig’s liver, and plant protein from millet. Nestlé said that using insect and plant protein would help protect the planet. The products are slated to go on sale next month in Switzerland. According to Nestlé, its Purina brand is sold in 70 countries.
