Fish bones are typically not dangerous to swallow but may become impacted within the gastrointestinal tract and cause clinical symptoms, according to The Indian Journal of Radiology & Imaging. Most fish bones pass through a person's system without causing serious complications.
An article in the Huffington Post states that, contrary to popular myth, fish bones are edible. Because fish bones are sharp, choking and internal cuts are potential hazards but can be avoided if proper care is taken. According to Serious Eats, fried fish bones are commonly eaten in Japan, especially as a quick snack or in bars. The frying makes the bones more palatable than they would otherwise be. People should not eat the bones of mammals, but the bone marrow is edible.
