Introduction
Under normal circumstances, pork liver can be safely consumed within 3 to 6 months when stored frozen at -18°C under well-sealed conditions; consumption beyond 6 months is not recommended, and the actual shelf life should be determined based on specific storage methods. Before freezing, pork liver should be thoroughly washed, cut into appropriate portions, and tightly wrapped with plastic wrap or placed in sealed bags. When ready to use, thaw it slowly in the refrigerator—avoid thawing at room temperature.
Under normal circumstances, pig liver can be safely consumed within 3 to 6 months when stored properly in a well-sealed container at -18°C. It is not recommended for consumption beyond 6 months, and the actual usability depends on the storage method. Details are as follows:
After thoroughly cleaning fresh pig liver, seal it airtight to prevent exposure to air before placing it in the freezer. This helps preserve its nutritional value and texture, with optimal quality within 3 months. If stored correctly without thawing and refreezing, and if there are no signs of spoilage such as off-odors or discoloration, pig liver may still be safe to eat within 6 months, generally posing no significant health risks.
If frozen for more than 6 months, or if improperly sealed or repeatedly thawed and refrozen, pig liver becomes prone to bacterial growth. Oxidation may also lead to nutrient loss and deteriorated texture, potentially resulting in spoilage symptoms such as graying, stickiness, or unpleasant odors. Consuming such spoiled pig liver may cause gastrointestinal discomfort, including abdominal pain and diarrhea, and should be strictly avoided.
Before freezing, pig liver should be thoroughly washed, cut into appropriate portions, and tightly wrapped with plastic wrap or placed in sealed bags. When ready to use, thaw it slowly in the refrigerator rather than at room temperature. For better food safety and nutrient absorption, fresh pig liver is preferable—purchase and prepare it immediately for best results.
