By yuck2nuts on Thu, 01-04-07, 18:35 The last time I checked with them (which was a while ago) I was told that if the code on the package starts with an H then it is safe because it was made at their Hyannis (nut-free) plant, but if the codes starts with an L or other letter, they cannot guarentee the safety because it is not made at their main Hyannis plant.
