Embodiment Construction
[0025] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0026] For the monitoring of cross-contamination in the existing food processing industry, it is usually based on the key links of food cross-linking to formulate a system that operators are not allowed to change jobs. The personnel are divided according to the cleanliness of the work area, and the personnel with the specified cleanliness can only work in the designated area and are not allowed to change posts. In case of crossing behavior, personnel can only go from high clean area to low clean area. The implementation of the system mainly relies on manual inspection and mutual supervision. Through manual regular inspections, the behavior of cross-contamination caused by personnel changing posts is...

The invention provides a cross contamination determination method and a cross contamination determination device. The cross contamination determination method comprises the steps of collecting the monitoring videos of areas of different clean levels; according to the monitoring video, drawing movement tracks of persons belonging to different clean grade areas; and determining the cross contamination condition of the areas with different cleaning levels according to the movement track. According to the method and the device, the cross contamination conditions of the areas with different clean levels can be determined according to the movement tracks of the personnel in the different clean areas, so that the accuracy of cross contamination risk judgment is improved.
Description
technical field [0001] The invention relates to the field of pollution monitoring, in particular to a method and device for determining cross-contamination. Background technique [0002] In the food processing and catering industry, the process of transferring pathogenic bacteria or harmful microorganisms between food materials and utensils or other food materials during the operation of food materials is called cross-contamination. In addition to direct or indirect contact between food and utensils or other ingredients, cross-contamination can also easily lead to cross-contamination when operators move back and forth between areas with different cleanliness levels. [0003] Food safety and quality are particularly important to the brand image of an enterprise. Therefore, in the food processing and catering industry, in order to prevent food cross-contamination, personnel are divided according to the cleanliness requirements of the work area. In the planning of personnel fl...
