Can a metal detector detect a higher amount of iron in our blood?

For example if I eat mussels, which contain high amounts of iron, am I more likely to set of a metal detector?

The answer to your question is yes, but not from food intake.  There is a disorder called Hemochromatosis which results in a higher than normal iron content in the body.  A normal person has ~4 grams of iron in their body, while someone suffering from Hemochromatosis might have up to 50 grams in their body.  These extreme cases have been known to set off standard metal detectors, such as those found in airports.

For reference, a 3oz portion of mussels contains ~6mg of iron.  You would have to eat thousands of mussels in one sitting before the level of iron in your body would be high enough to set off a detector.
