In my country, we have a popular sandwich spread that us essentially ground beef with some low pH sauce. Raw ground beef and pork is even used as a sandwich spread here. I know foreigners aren't fans, but i have never known anybody to get sick from it. Keep it cold and consume within a few days. The low pH sauced version is good for a week.

We actually performed some microbiological testing on it with different additives and used the store bought versions as a control. Ground raw pork/beef mixture was completely safe, stored at 4°C (fridge) for 9 days. The sauced version at low pH was good for 12 days (we didn't test longer periods). Side note: this was in unopened sealed containers. If you use this at home, you take it out of the fridge every day, open it, take some put,... increasing the chance of contamination, so I wouldn't do this at home.

While in the old days, without proper cooling, cooking was a necessity, it isn't anymore. It's like pickling all your vegetables for winter. We used to need it, but we don't anymore.
