Worms appear inside live beads because the internal structure of the egg has been damaged or the live beads have deteriorated in a hot environment. Live beads are a famous local specialty of Nanjing, which are chicken embryos that are about to hatch into life but are not fully formed. Since live beads are liquid inside, if they are not stored properly, they may be contaminated by bacteria or deteriorate in a high-temperature environment, resulting in the destruction of the internal structure and thus the development of worms. Therefore, when consuming live beads, attention should be paid to the preservation conditions and consumption hygiene.
