When these folks are faced with the gruesome reality of how a farm animal is converted into their meal, they will be disturbed or disgusted. If they are given the opportunity to witness it happen, they will be thoroughly traumatized. And if they are given the responsibility to perform the deed themselves, they will make an effort to shirk their assignment. The choice of converting to vegetarianism, if they haven't already, will definitely be considered.
There are a multitude of ways a character can find themselves in this situation. Common examples include visiting a relative's old-style farm, or students learning about nutrition and the food chain. A gag that shows up on occasion is when a Cloudcuckoolander tries to slaughter an animal in a blatantly inappropriate venue or public space, such as a family party.
If kids are around, you can expect them to bond with the animal and refuse to part with it as it has become their pet. This can result in Adopt the Food.
In most cases, the actual killing of the animal is avoided, (or at least not shown) as this is typically a comedy or drama trope used in works that aren't dark enough to portray the actual slaying of an animal.
- Silver Spoon: One of the realities that Yugo Hachiken has to accept when he decides to enroll in an agricultural-vocational high school is that the animals used for the practicums are sometimes slaughtered for meat. The first time he encounters this is when a third-year student nonchalantly beheads a chicken right in front of him in order to make smoked chicken as thanks for Hachiken and a couple of his friends helping him catch the chickens that got loose. Then Hachiken gets quickly attached to a runt pig he names Butadon despite knowing that he's destined for the slaughterhouse once he's three months old. The first sign that he's accepting this reality is when he's staying with Aki's family during summer break and her grandfather accidentally kills a deer while driving his truck. When he decides to take advantage of the situation for free meat, he offers Hachiken the chance to butcher it while being guided through the process; after a few minutes of hesitation and blindfolding the dead deer, he decides to do so. Another sign that he accepts this reality is when he decides to buy the meat that Butadon will be turned into.
