My question: Yes / no, is the following a verifiable fact?
"Pigs are clean animals and do not carry parasites in their body."
Please think gradually:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
