Buying seeds from O/S???

I'm a big believer in quarantine laws and so always try to follow the rules closely. Unfortunately, I also think quarantine is a joke at the moment. I've recently imported two lots of rose seeds from the U.S. and from India and went to the trouble of finding out what to do, alerting quarantine of their arrival, making sure they were on the allowable imports list, etc. The lot from India came in with a quarantine inspection sticker stuck to it but the one that came in from the U.S. hadn't even been opened despite being clearly marked on the front that it contained rose seeds. The lot of seed that came in from India were very clean and had been sorted carefully to ensure only good quality seed came through. The batch from the U.S. came in and there was fungus growing on some of the seed because the hip flesh hadn't been cleaned off properly and they were too soft (a sign of immaturity. Before they harden they are prone to fungal infections). As a rule I always keep the seeds in tuff plastic bags for a few months whenever I get seeds in from O/S and I'm glad I did with the seeds from the U.S. because a week after arriving a few small adult wasps chewed their way out of one batch of seeds and into the bag. They died in the bag but this wouldn't have happened if quarantine had inspected it and treated it with insecticide as they were meant to have. So... that's why I was anxious about what other people's experience was with their O/S cactus imports (despite having a feeling that it probably would have been ok).
