The main objective of this survey was to obtain baseline information regarding the presence and levels of undeclared allergens and gluten in Halloween-themed candies and chocolate products. Of the 356 samples tested, 10 were found to contain undeclared allergens, specifically beta-lactoglobulin (BLG) and casein. All positive results obtained during the course of these surveys were forwarded to the CFIA's Office of Food Safety and Recall (OFSR) to determine if the levels found would pose a health concern to allergic individuals. The extent of the follow-up actions taken by the Agency is based on the level of the contamination and the resulting health concern as determined by a health risk assessment. 4 Halloween-themed candies containing both BLG and casein were deemed to represent a health risk and were recalled.
