Opinion: Your dog feels as guilty as she looksA short mention of our work on disgust in this opinion piece written by Frans de Waal.

That's disgusting! How primates decide
|
Fastidious apes turn up their noses at filthy food"Just like humans, small rainforest apes called bonobos lose their appetites when food is placed on or near faeces."
Is disgust a universal emotion?"She bought replicas of poop online from Barcelona, Spain, which has a scatological fixation. “When I arrived in Gabon, I had two bags – including one full of fake poops,” recalls Sarabian. “At the customs, they were stopping everyone to check the bags and I was like ‘oh nooo, what am I gonna say?’ I thought I may have to bribe someone for getting fake poops in the country, but by the time my turn came, they were checking one bag [per passenger] and luckily they chose the other bag.” Sarabian blogs about her fieldwork here."
What grosses out a chimpanzee?"In 2015, researchers from Kyoto University's Primate Research Institute went to the Primate Center at the 'Centre International de Recherches Médicales de Franceville' (CIRMF) in Gabon to test whether chimpanzees are grossed out by some of the same things as humans, particularly those that are sources of infectious disease."
Monkeys keep their food clean, sort of"We all have our standards. For humans, it’s the five-second rule. For macaques, it’s “think twice before eating food off a pile of poop.” The monkeys have several ways of keeping their food (sort of) clean. And the most fastidious macaques, it seems, are rewarded with fewer parasites."
Scientists prank monkeys with fake poop for real research"Proving that there really is a job for everyone, scientists at Kyoto University have pranked monkeys with plastic made to look like poop, and got a paper published out of it [...]"
The yuck! factorIn his latest book "Mama's last hug" (2019),
Frans de Waal talks about "Emotions that make us humans" and refers to our work on disgust in non-human primates. 
Children's book about animal emotions
In her last book, Lotte Stegeman dives into the world of animal emotions by compiling scientific stories about jealousy, fear, anger, joy, disgust, grief, empathy, pain, and love. Super happy to have contributed to the chapter on disgust and shed light once again on the marvellous Kojima macaques (by telling the anecdote that put me on that 'disgust journey'...) Watch out for the translated version coming soon!

A sense of disgust in bonobos?"These primates, known for their liberal attitudes toward sex, are also generally open-minded when it comes to new foods -- as long as the grub is clean."
Weird chimp experiments reveal their bizarre poop eating etiquette"Chimpanzees famously fling their own poop and have no problem picking seeds out of it, but scientists say our primate cousins may be a bit more hesitant about touching feces that isn’t their own. It may sound kind of obvious that they would be grossed out by a stranger’s poop, but disgust of another chimp’s biological goods hadn’t been observed in these animals before."
Chimps will happily eat their own poop, but touching moist things grosses
