Thank you for your valuable feedback. Yes, liver is a detoxifying organ so I also used to believe liver would accumulate toxins but later found out that it was not true. The mechanism is different. Therefore I consume beef liver over the last 3 decades and had no side effects. I pedantically get checked for many blood markers. If animal liver holds toxins healthcare professionals wouldn't recommend it as a nutritious food, they wouldn't eat it itthemselves and health authorities would ban it.
