Has the spice external structure impact on its microbiological quality?

I have contaminated spices with different microorganisms (bacteria, molds). Meanwhile, I've noticed that decay of molds, for instance, after ozone treatment is difficult to achieve. Some of spices such as cardamom has a "pod" structure and despite of maintaining a proper relative humidity, I am not able to obtain sufficient mold reduction. Is there anyone who has similar observations? How should I treat such kind of spices?

Dear Aga,

Maybe, you need longer time of ozone action. It has also been indications in the literature that ozone needs a higher humidity in the air to be really effective.
