Answer ( 1 )
Heat resistance in a nutshell
Salmonella is not very heat tolerant. At 70°C (158°F) it is killed in well under a minute. That is why most food safety guides pick 74°C / 165°F as the target internal temperature, it adds a small safety cushion.
D values you can use
The D value is the time needed at a given temperature to cut the population by one log. Typical numbers in normal foods are:
• 60°C → about 2–5 min
• 65°C → about 30–60 s
• 70°C → about 5‑10 s
Six D values give a 6‑log kill that regulators call safe enough.
Food matrix effect
High fat or dry foods protect the cells a bit, so peanut butter needs longer than chicken broth at the same temperature.
Practical takeaway
Get the coldest point of the food to at least 74°C for a few seconds or hold it at 60°C for the times listed in sous vide tables and Salmonella will be gone.
