I wondered if anyone has had anything similar happen to them and what was the result. I recently found a maggot type thing in a box of horlicks! ewww...yes. Anyway I called the company GlaxsoSmith and they sent me a voucher for a replacement and a bag to send the box off with maggot to investigate. Not that they seemed to care what I found!
I also called environmental health and they have said they will analyse it before its passed back to GS.
Just wondered if anything else like this has happened to anyone and what the outcome was.
