Hi Fiona,

You can find actual tests of Safe Starch in the files section of the group.  As they are not guaranteed to be below 10% ESC+starch and the fat level is higher than our guidelines we do not recommend feeding them to an IR/PPID horse.  There are many, many posts about Safe Starch that are more recent than 2006 - you want to do a search by entering "safe starch" - https://ecir.groups.io/g/main/search?p=recentpostdate%2Fsticky%2C%2C%2C20%2C2%2C0%2C0&q=%22safe+starch%22.  That search provides 1515 messages including yours from this morning.
