The term "measly beef" refers to the presence of which of the following in muscle tissue?

The term "measly beef" specifically refers to the presence of cysticerci, which are larval forms of the beef tapeworm known scientifically as Taenia saginata. When cattle are infected with this parasite, the cysticerci develop in their muscle tissue, leading to the characteristic appearance of the meat. The presence of these cysts (or cysticerci) can visually affect the muscle, giving it a "measly" or granular look, hence the term.

The implications of finding "measly beef" extend beyond aesthetic concerns; there are potential health risks to humans who consume undercooked or contaminated beef. If ingested, the cysticerci can develop into adult tapeworms within the human gastrointestinal tract, leading to further complications.

Understanding this specific condition is crucial in veterinary and food safety contexts, as it highlights the importance of monitoring livestock health and ensuring that meat products are safe for consumption.
