Additionally, liver can be contaminated with bacteria, such as E. coli and Salmonella, which can cause food poisoning.
To minimize the risks associated with eating liver, it is essential to handle and cook it properly. Liver should be stored in the refrigerator at a temperature of 40°F (4°C) or below, and should be cooked to an internal temperature of at least 165°F (74°C) to kill any bacteria that may be present. It is also essential to choose liver from reputable sources, such as local farms or butcher shops, to minimize the risk of contamination.
Can liver be consumed by individuals with certain health conditions?
Liver can be a nutritious and healthy addition to a balanced diet, but it may not be suitable for individuals with certain health conditions. For example, individuals with high cholesterol or heart disease may need to limit their intake of liver due to its high fat and cholesterol content.
Additionally, individuals with certain liver diseases, such as liver cirrhosis or liver cancer, may need to avoid eating liver altogether. This is because liver can be high in toxins, such as heavy metals and pesticides, which can exacerbate liver disease. It is essential for individuals with certain health conditions to consult with their healthcare provider or a registered dietitian to determine whether liver is a safe and healthy choice for them.
