**3.** *Taenia* **egg survival and dispersal**

Taeniid eggs can survive for up to a year in moderate temperatures and are commonly found on vegetables, soil, and water samples, posing a risk to consumers. Invertebrates may serve as transport hosts for taeniid eggs, and wastewater treatment systems are not completely effective in removing them, making access to surface water and using sewage sludge as pasture fertilizer significant risk factors for bovine cysticercosis [5, 6]. However, flies and dung beetles play no significant role in transmitting *T. solium* to pigs, and corralling reduces but does not eliminate

the infection risk with cysticercosis (**Figure 2**). Other mechanisms of egg dispersal should be evaluated for a better understanding of transmission dynamics [8].
