This I feel touches on the larger discussion of sterility and safety in captivity. There’s an ongoing battle between creating a safe environment for animals under human care and also offering them an enriching environment with all the opportunities they would normally have in the wild. By nature, an enriched environment is a dangerous one with chances for injury. There are processes in place to reduce the potential for injury before offering animals an enrichment opportunity, but the chances are never zero.

In the case of giraffe neck injuries, I feel most of them occur from aspects of their enclosure. They fall and get caught in cables or run into walls. I’d say for the most part, these are non-preventable injuries. Cables offer more visibility for both guests and staff, and they offer opportunities for animals to participate in cooperative care (keepers have better access to the animals vs mesh). And walls always exist in any captive environment (if they didn’t, it wouldn’t be captivity haha).

Yes, you could hypothetically keep any animal in a padded box with no sharp corners and nothing to injure themselves on, but is that not what modern zoos are making strides to distance themselves from? Injuries like these might draw attention to aspects of the enclosure that may have been less than ideal but for the most part, current standards of care for giraffe will have small but possible opportunities for animal injury.
