Although reported contamination is fairly low, the warning is that swordfish should be consumed infrequently due to a prevalence of low levels of mercury. Most "oily" fish - like swordfish - share similar warnings worldwide, and fish near the top of the food chain are more likely to accumulate damaging levels by eating other fish that have accumulated high levels by eating smaller fish who ...

On the subject of other exotic foods:

They apparently are planning to build a brand new "zoo" to display the croc, and hope the whole town will get rich off the tourists who will come flocking in.

There apparently is no existing zoo.

They apparently have not considered that they'll have to feed it.

It ate (they think) at least one fisherman in July (for a snack) and witnesses saw it take a water buffalo in August. It was hungry enough to be baited into four traps (which it destroyed) and finally to be snared within the last few days.

[hmmm. Do we have more fishermen to spare or more surplus water buffaloes? It probably won't eat lawyers or Republicans due to professional courtesy. ...]

Better to boil the $@#!% now and start a belt factory(?). But they might not have a refrigerator big enough to hold 2370 lb of meat, so maybe someone has a recipe for pickled crocodile? Any suggestions?
