HACCP is applicable when there are control measures which can be applied to prevent, eliminate, or reduce the occurrence of a food safety hazard to a consumer, but much of the life cycle of a food does not lend itself to strict application of HACCP principles. FSIS HACCP is mandatorily applied to meat and poultry slaughter and processing establishments to reduce harmful bacteria on their products. FSIS manages the HACCP plants under continuous inspection of the FSIS inspectors: Inspector in Charge (IIC), Public Health Veterinarian (PHV), on line/off line Consumer Safety Inspectors (CSI). More than 7,600 inspection personnel inspect nearly 6,500 meat, poultry, and egg processing plants, and verify that regulations regarding food safety and other consumer protection concerns are met. But only half of violations observed are recorded on the non-compliance report due to inspector shortages. The change from traditional sanitation system to HACCP system has been difficult because of several factors: Lack of technical expertise in processing facilities makes a scientific hazard analysis difficult, preventive measures and validation efforts are not supported by data, plant management and inspectors concentrate on what they know, plants are still very dependent on the regulatory agency for guidance, focus is on regulatory procedures more than determining food safety issues, and also plants are less efficient at producing and maintaining records that are not specifically tied to production lots. However HACCP is an effective tool in food safety continuum.

This study was surveyed to evaluate and recognize the distribution characteristics of indoor air pollutants(IAPs) such as the total volatile organic compounds(VOCs), formaldehyde(HCHO), PM10, carbon dioxide(CO2), nitrogen dioxide(NO2), ozone(O3) and radon in 10 elementary schools located in urban, rural, and industrial complex area from November 2005 to February 2006. The average concentration of IAPs were 117.9㎍/㎥ as in PM10, 1,971ppm as in CO2, 486.6㎍/㎥ as in TVOC. These chemical's concentration was exceeded the indoor air standards of the Department of Education in Korea. The indoor concentrations of ozone and toluene was lower than that of outdoor and other pollutants showed the opposite tendency. In schools located industrial complex area, the outdoor concentration of TVOC was higher than that of urban and rural area. Based on the results above, PM10, CO2, TVOC have to be in the order of priority to improve the indoor environment in school. Also it should be performed in the detailed survey considered by the seasonal variation because this study showed cross-sectional results.
