I just returned from the Costco store located in Vista CA where I stopped by the bakery and asked to speak with the department manager regarding grit and/or sand in their pumpkin pies. She said they used to receive the pumpkin filling from Lilly but since the last "year or more", all of the pumpkin puree has been coming from a company called "Seneca". (

Like most of us who are aware of the issue, I thought it was Lilly (Nestle) who supplied Costco and according to the Bakery manager, they used too before Seneca took over. Before learning of this, I wrote to Lilly (Nestle) and received a reply back saying among other things, this...
"Libby's carefully picks and transports pumpkins to our factory. We use multiple washing systems on the pumpkin but, like lettuce, some tiny grit or sand can make it through the processing system. During the pumpkin processing, we remove the seeds and skin of the pumpkin. However, at times minute pieces can make it through our very fine screens (the holes are about the diameter of the dot on the "i" in the name Libby's). These can also contribute to the grittiness."
So there you go...Libby "kind of" admits there is an issue with the pumpkin processing system. However, what they didn't say is anything about Costco and that could be because they no longer are the supplier. If this is the case then our culprit is Seneca, at least regarding the question of why sand and/or grit is turning up in Costco's pumpkin pies. I will see what Seneca has to say and if worthwhile, I will post it here.
