Better: Above 60°C pasteurizes the contents so killing all bacteria.
Technically pasteurization is met by holding the food over a specific temperature for a specific time, so over 63-65°C for 30 minutes, or 100°C for 12 seconds.
Normal pasteurization is very similar to cooking in times and temperature, and so pasteurization cooks both the food, altering texture, appearance and taste, and the bacteria.
UHT means ultra high temperature pasteurisation, which heats, eg, milk well over 100°C for only a couple of seconds and immediately cools it, minimizing the alteration of the milk.
So, by keeping the stew over 70°C, the stew is completely food safe.
This has already been put to rest by the scientists, unsurprisingly.
It’s much more common among those who got covid without having had the vaccine (either on those who had covid before the vaccine, or those who didn’t take it).
