Safety

The meat is boiled before fermenting. The database says to keep it in a refrigerator for up to a week; without refrigeration it sours quickly. The method leaves the boiled meat to ferment for 1–2 days and gives no salt or acidity figure. The CDC says bacteria multiply rapidly between 40 °F and 140 °F (about 4 °C and 60 °C), and perishable food such as cooked meat should not be left out for more than 2 hours, or 1 hour above 90 °F (about 32 °C).
