SAIDS initially pointed to the death of a technician at the contracted lab as part of the reason for the delay. But now it sounds like there was an additional 7 week delay? If that is the case, they should, and probably will, be in trouble for it, as it clearly cost Impey a lot of financial loss and stress. The passing of the lab technician is the truth, sadly - I knew him well. As for the amounts that might be needed, and if enough could have transferred from the pharmacist's hands to the capsules, I've read that certain hair-loss products for men should not be handled at all by pregnant women, as enough can seep through their skin to cause birth defects? Not sure if that is true or not. And some vitamins and minerals in multivitamin supplements are measured in micrograms, and is still enough to have an effect, so trace amounts of probenicid could probably also have an effect, and thus be detected? Anyway, I'm glad he has been cleared, and I really hope that they aren't lying about the contamination.
