(1) Current status of aquatic product safety testing
China is a big fishery country in the world.
1.
With the progress of science, the development of society and the continuous improvement and enrichment of people's living standards, coupled with the continuous changes in the production, processing, circulation, and production methods of aquatic products, new technologies have brought new products one after another
(1) Problems in the production and processing of products are prominent.
(2) The conditions of aquatic product processing enterprises are simple, lack of safety and health knowledge, and safety and quality awareness.
(3) The business order of the circulation link is not standardized, and there are hidden dangers to the quality and safety of aquatic products.
(4) Insufficient supervision, frequent occurrences of aquatic product quality and safety accidents such as Beijing "Fu Shou snail" and Guangzhou Angiostrongyliasis.
2.
The quality and safety testing of aquatic products has a lot of content, but the main aspects and testing methods are as follows
(1) Heavy metals Heavy metals have an obvious tendency to accumulate in aquatic animals that take plankton as their food chain
(2) The variety of pesticides and pesticides is increasing, including insecticides, fungicides, rodenticides and plant growth regulators
(3) Fishery medicines The internationally valued residual drugs include antibiotics, sulfonamides, furans, quinolones, hormones, and genetically modified drugs.
The detection method of oxytetracycline, tetracycline, chloramphenicol, chloramphenicol, and sulfonamides is high pressure liquid chromatography; the detection method of methyltestosterone and desmethyltestosterone is CC-MS; the detection method of diethylstilbestrol is ELISA
(4) Toxins Harmful algae toxins accumulate in fish, shellfish and other organisms themselves or through the food chain, causing harm to organisms and even humans
(5) Food-borne diseases caused by microorganisms are one of the main factors affecting food safety
