Segment Information | 15. Segment Information The Company has two reportable segments: Food Safety and Animal Safety. The Food Safety segment is primarily engaged in the development, production and marketing of diagnostic test kits and related products used by food producers and processors to detect harmful natural toxins, foodborne bacteria, allergens and levels of general sanitation. The Animal Safety segment is primarily engaged in the development, production and marketing of products dedicated to animal safety, including a complete line of consumable products marketed to veterinarians and animal health product distributors. This segment also provides genomic identification and related interpretive bioinformatic services. Additionally, the Animal Safety segment produces and markets biosecurity products to assist in the control of rodents, insects and disease in and around agricultural, food production and other facilities. The results of each segment are regularly reviewed by the chief operating decision maker ("CODM") to assess the performance of the segments and make decisions regarding the allocation of resources to the segments. Our CODM is our Chief Executive Officer. The performance measure that the CODM uses is operating income. Many of our international operations originally focused on the Company’s food safety products, and each of these units reports through the Food Safety segment. In recent years, these operations have expanded to offer the Company’s complete line of products and services, including those usually associated with the Animal Safety segment such as biosecurity products, veterinary instruments and genomics services. These additional products and services are managed and directed by existing management and are reported through the Food Safety segment. Segment information is as follows:
