So far so great!

Probably too late, but I wouldn’t bother throwing it out @MitchCorrie: your strategy of 1-2g at a time and not every day should easily keep you within safe limits: bear in mind that this is a spice that people use all over, all the time, and is available for sale in normal shops without any warning label. Don’t waste what you’ve got, but do buy the good stuff next time!
