The Guidelines have been sent to all Member Nations and Associate Members,of FAO and WHO as an advisory text, and it is for individual governments to decide what use they wish to make,of the Guidelines.,CAC/GL 17 Page 2 of 7,EXPLANATORY PREFACE,The safety of canned foods is assured primarily by the application of Good Manufacturing Practices,(GMP's) in the manufacture of the containers, processing and handling the container in the processing,establishment, and storage and distribution of the finished product. When the safety or acceptability of a lot of,canned food is in question the first action should be the verification that GMP's were followed. However, there are,instances e.g., international trade, when safety or acceptability of a lot may be in question and no evidence is,available which would give assurance that GMP's had been followed. In such situations it would be appropriate,for a canning expert to assess the acceptability or safety by both inspection and reference to any pertinent,documentation relating to processing, shipping, etc. of the lot which may be available. The type of examination,carried out under such circumstances will vary and be dictated by the particular problem or situation. The,examination may be expected to reflect the experiences of the particular expert engaged.,Some container defects can increase the potential for microbiological contamination of canned foods,resulting in spoilage and in some instances in foodborne illness. While some of these defects are hidden, many are,visible on the container surfaces permitting their detection without destructive analysis. Control of such defects,that is preventing their occurrence, is exercised in a number of critical control points in the GMP's to assure that,the risk of post-process microbial contamination which may result in spoilage and food poisoning is minimized. It,is in this sense that inspection of lots of canned foods for visual defects can be a viable means to determine their,acceptability. Since such inspection is non-destructive it permits the inspection of larger numbers of containers at,minimal cost. However, when such inspections are carried out, only statistical based sampling plans should be,used and the choice of sampling plan depends on the nature of the inspection being undertaken.,It is important to recognize that sampling inspection for defects alone cannot give the same level of,assurance to GMP's because:,1. not all defects are apparent by visual inspection; and,2. there are limitations on resources available for the application of,statistically based sampling plans.,Control of visual defects is just one of the GMP's relevant to assuring that the risk of contamination with,microorganisms which may result in spoilage and food poisoning are minimized. From this, it is clear that,sampling plans need to be considered in relation to their intended purpose and to the acceptable and unacceptable,defects.,End-product examination for visual defects should not be over emphasized as it may divert attention,away from those GMP's which cannot be monitored by end-product examination (see Codex Alimentarius,Recommended International Code of Hygienic Practice for Low-Acid and Acidified Low-Acid Canned Foods,CAC/RCP 23-1979 (Rev.1, 1989, Rev. 2, 1993)).,Sorting may be appropriate to remove defective cans but this should be decided at the "retention" stage,by a person with experience in the evaluation of defective cans.,IT IS MOST IMPORTANT THAT SAMPLING INSPECTION OF LOTS OF CANNED FOOD FOR,THE PRESENCE OF VISUAL DEFECTS IS NOT THE ONLY BASIS FOR JUDGING PRODUCT TO,BE FIT FOR HUMAN CONSUMPTION,CAC/GL 17 Page 3 of 7,1.
