Abstract:

Traceability systems have become an effective method of providing safe food supplies and connecting producers and consumers. In the current period, most studies of traceability systems for meat foods focus on production information transmission and system hardware implementation. However, there have been fewer studies on mining of production information and setting up of product safety models. In this study, FTA and FMECA which have been widely used as two mature risk analysis approaches in combination with Delphi method were introduced into the food industry to set up a traceability method for determining hazard sources in meat foods. Meanwhile, the method was applied to analyze the problem of coliform counts in beef cattle slaughtering workshops exceeding the standard. It was found that the method was effective in finding hazard sources, ensuring production safety and improving production regulations.
