A blocking-transmission vaccine against trichinellosis will allow preventing swine infection and will contribute to disease control. In this chapter, different vaccine candidates so far developed against T. spiralis, including first-, second-, and third-generation vaccines, are discussed.

What kills trichinosis?

The actual temperature that kills the trichinella parasite is 137°F, which happens to be medium-rare. But be forewarned: Every iota of meat must hit that temperature to kill the parasite, and cooking bear meat to medium-rare isn’t a guarantee of that.

Does trichinosis go away?
