cod liver oil dangerous?

Hello~ I have been taking Cod Liver Oil (and other supplements) for about three weeks and I feel great. I have even noticed that my skin has been looking healthier from the liver oil. Howeverm someone just emailedd me the following excerpt from the Wellness Guide to DDietary Supplements. Is there any truth to this? Any help would be greatly appreciated. Thank you:

• Cod liver oil, bottled or in capsule form, has special problems. It is the richest source of vitamins A and D. Just one teaspoon has 4,500 IU of A, for instance, and the standard dose is one to three teaspoons a day. The capsules contain less oil, but the vitamin can still add up, especially on top of the amount you get from foods and from a multivitamin, if you take one. Recent studies have found that as little as 6,000 IU of vitamin A daily can interfere with bone growth and promote fractures. And women of childbearing age should not exceed 10,000 IU of vitamin A because of the risk of birth defects. Too much vitamin D can also be toxic.

• Cod liver oil is made from livers, of course. The liver is a filter, so toxins (such as PCBs) get concentrated there. Thus cod liver oil is more likely to be contaminated than other fish-oil supplements.
