here it is. It was an email. To me it sounds like they don't use shared lines, but it is a shared facility.
Thank you for your email regarding Ghirardelli Chocolate. Ghirardelli currently manufactures products containing the following tree nuts: almonds, coconut and hazelnuts; all the bars and squares made in the facility share equipment with products containing these tree nuts. Ghirardelli no longer uses peanuts in our facility; we stopped using them in the year 2011.
Ghirardelli takes the following measures to reduce cross contamination on our production lines: lines are cleaned between the changing from one product to the next.
The chocolate chips (60% Bittersweet, Semi-Sweet, Mini Semi-Sweet, Double Chocolate and Milk Chocolate) do not contain tree nuts; moreover, the chocolate chips line does not make products containing tree nuts. The Classic White Chips are produced by a co - manufacturer and are made on equipment that makes products containing peanuts and tree nuts.
We hope you continue to enjoy our products in the future.
