There have been two major recalls from Big Pharm (McNeil and Pfizer) who used empty plastic containers that somehow absorbed a terrible chemical (fungicide) from storage, and when they were filled with drug, and sealed, the fumes reacted with the contents and bingo...

The first recalls for Tylenol etc products started 2 yrs ago, and
the recent Lipitor by Pfizer was just a few days ago.

It is possible the empty plastic jars used by Jarrow had a similar problem.

Any weird off odors coming off drugs when you open the bottle should be returned and not used.

This could be more than a leaky capsule or broken one. It could also be rancid odors from being stored in temps that are high.
One never knows what happens during transit etc.
