Study On Edible Security And Supervision System Of Puffer Fish

Puffer fish has been consumed as gem of the fish for thousands of years in China.However,it contains Tetrodotoxin(TTX),which is a kind of highly poisonous alkaloid and its toxicity is 1,250 times than editpotassium cyanide.Improper processing or taken internally could result in toxication,even death.So there are a bunch of people "brave enough" to be "poisonous blowfish eaters" in China.Even,though,it's always forbidden of having puffer fish in China.Over the years,as the aqua cultivated toxicity control technology' s development,toxicity in cultivated puffer fish can be limited in safe level or even non-toxic.Recently,National Health and Family Planning Commission has passed the safety evaluation and requested public comments on breeding Fugu rubripes(Takifugu rubripes)and Takifugu obscurus as novel food material.has It can be expected that,once the cultivated puffer fish is approved to be as food,the domestic consumption market will be definitely stimulated.Nevertheless,some wild puffer fish or the other species beyond the approval would also be put on the tables,which is a potential risk to having puffer fish.Both the puffer fish dealers and consumers don't have the capability to distinguish the wild toxic puffer fish against the cultivated ones,and some catering places are not qualified,especially we don't have the related regulations,all these facts bring huge risk to the consumers.This thesis aims to give regulative recommendations and supervision measures against the possible food safety problem with the approval of the cultivated puffer fish and the potential risks,such as inadequate regulation system and standard system,deficient manufacture procedure,and interfusion of mild or non-food puffer fish during circulation and food service.To complete the study,this thesis has retrieved the relevant literature both at home and abroad in recent years.By sending questionnaire which covers the current chain of puffer fish from cultivation to consumption;and calling a meeting with the inspection authorities,industry association,research experts and workers in catering trade to discuss this topic.Besides,by carrying out relevant training to practitioners and conducting lab testing to compare the toxicity of the cultivated puffer fish and the wild ones before and after the processing to confirm whether the measures defined by the regulation effectively to lower the toxicity of Tetrodotoxin..Investigation results show the two species puffer fish listed in the bulletin can be consumed safely,but the wild ones or the species other than the listed ones are not safe and required for effective measures to strengthen supervision.Therefore,this study suggests that government should establish the closed-loop supervision in the whole chains of Puffer fish,including cultivation,setting up systems to evaluating the qualification of production and business units.Not only the certificates of origin should throughout all links,but also asking for certification and invoice,as well as staff management system which in accordance with good manufacture procedure(GMP)should be practicable..A series of regulations have been prepared to ensure the safe consumption of puffer fish,such as Regulation on the Cultivation of Puffer Fish,Safe Processing Manual of the Cultivated Puffer Fish,Regulation on the Personnel Training of Cultivation Puffer Fish,and Certification Review on the Catering Units in Dealing with the Cultivated Puffer Fish.
