When it comes to canned food, the age-old saying “when in doubt, throw it out” is usually the best policy. Opened canned food can be kept for a limited period of time depending on the type of food and how it is stored.
Canned food with a high acid content, such as tomatoes or fruit, can last for up to three days in the refrigerator as long as they are stored in an airtight container. Low-acid foods such as vegetables and meats can last up to four days if stored properly. It is important to remember that once a can is opened, it should not be left at room temperature for more than two hours.
Any opened canned food that has been sitting out for more than two hours should be discarded immediately. Bacteria growth begins to occur rapidly when food is left at room temperature and this can lead to serious illness if consumed. If a can has been opened and then refrigerated, it should be eaten within four days or discarded.
Freezing Opened Canned Food
Opened canned food that is not going to be eaten within four days of opening should be frozen for longer storage. Foods such as vegetables, meats and fish can all be frozen and will keep their flavor and texture better than if they were just left in the fridge for an extended period of time. It’s important to remember that all canned food should be thoroughly cooked before being frozen, otherwise bacteria growth may still occur during freezing.
Conclusion
In conclusion, opened canned food should not be left out at room temperature for more than two hours before being discarded. High-acid foods such as tomatoes or fruit should be eaten within three days of opening while low-acid foods like vegetables and meats should be eaten within four days if kept in the refrigerator or frozen for longer storage.
