This sounds scary. But hepatitis E is not common in the United States. You can avoid hepatitis E by practicing good hand hygiene and cooking beef liver to an internal temperature of 160 degrees Fahrenheit.

Food Poisoning

As with any food, food poisoning is a risk, but it is very low. You are more than twice as likely to get food poisoning from fruits and vegetables. Only 22% of food poisoning infections arise from meat and poultry .

You can prevent food poisoning by cooking liver to an internal temperature of 160 degrees Fahrenheit.

Vitamin A Toxicity

Vitamin A toxicity results from consuming excessive amounts of vitamin A. Symptoms of vitamin A toxicity may include :

Pregnant women who experience vitamin A toxicity may have an increased risk of birth defects. However, vitamin A toxicity is rare. It is most often caused by supplements containing retinol as opposed to natural food sources.

Consuming more than 600,000 IU of vitamin A may lead to poisoning. You may also experience vitamin A poisoning if you regularly ingest more than 25,000 IU of vitamin A daily .

You can avoid vitamin A toxicity by being mindful of your beef liver consumption. A 100-gram serving of beef liver contains 16,899 IU of vitamin A. You can eat this daily without risks of vitamin A poisoning.
