The CCFRA glass reference library contains information on over 700 different types of glass. It is clear that types of foreign matter referrals sent to CCFRA represent the more serious concerns and this is why 1072 (45.7%) of the 2345 incidents involved glass. Foreign matter incident data are held by most manufacturers and will be highly dependent on the product and type of processing operation. This information is held in strict confidence and there is little, if any, published information on the nature of complaints.
