Which option lists the complete time-temperature combination for roast pork or ham?

• A. 130 Degrees for 112 Minutes, 140 Degrees for 12 Minutes, 145 Degrees for 4 Minutes
• B. 130 Degrees for 112 Minutes
• C. 140 Degrees for 12 Minutes
• D. 165 Degrees for Less Than One Second

Answer: (A)

The idea being tested is pasteurization through a complete time–temperature progression. For roast pork or ham, safety can be achieved not just by one temperature, but by following a sequence that delivers the necessary microbial kill over time. The option listing 130°F for 112 minutes, then 140°F for 12 minutes, and finishing at 145°F for 4 minutes provides a full progression that, together, meets the required lethality for the meat. The final 145°F hold ensures the product reaches a safe level, while the earlier steps gradually bring the temperature up in a controlled way. This is why it’s the best choice: it includes all the steps needed to reach safe pasteurization. The other options are incomplete, either omitting stages or using an impractical quick, high-temperature burst that doesn’t fit the standard complete time–temperature approach for roast pork or ham.
