Raw materials acceptance

Raw fish come from the official registration farms. Carry out pre-check prior to the acquisition, the raw fish can’t purchase until it pass inspection by the quality control department to test drug residues of sampled on breeding sites. Raw materials to the plant must be provided the official registration farm’s materials supply certificate. If farm record number in accordance with laboratory test reports the raw fish

Metal Detecting

Products do not exist in the Fe≥Ф 2.0 mm,SUS ≥Ф 3.0 mm,Non-Fe≥Ф 3.0 mm of impurities.

Checking Frequency:Before work, during work every one hour and after work.

Monitoring Frequency:Continuous monitoring

Corrective Action

1.If discovering the failure of metal detector, we should adjust or replace metal detectors. Before one hourthe products that was passed through metal detector will all back through metal detect or to check.

2.To isolate and evaluate check out products that it content the pieces of metal, and then to find and analysesthe source of metal debris,the products will be abandoned.

Verification

1. Using FeФ2.0mm,Non-Fe Ф 3.0 mm, SuSФ3.0mms three test blocks are respectively check sensitivity of metal detector before the start of the production process and every one hours during process and end of production.

2. Review monitoring, corrective action, and verification records within 1 week of preparation.

The outer packing

Critical control point:the outer packing (label inspection)

The critical limits:①All finished products should use the writing of the importing country to mark that ” Keep frozen until used, thaw under refrigeration immediately before use. Remove from the vacuum package before thawing.” on the label. ②All product labels must be using the writing of the importing country to mark the information of allergy

Corrective measures:①If spot checks found that the label does not meet the requirements must be return the label or packaging material before the production of each batch of products .②If spot checks found that the label does not meet the requirements must be pasted isolated identification during the production and the end of production of each batch of products,to find out the reasons of unqualified and to determine corrective measures, and then we will be replaced the correct label or the correct packaging of products.

The frequency of monitoring: Each batch of products should have sport check once every 1 hours before the production, during the production and the end of production

The number of spot checks: 3-5 / time
