Description
Technical field
The present invention relates to food inspection to sample storage device auxiliary equipment, and in particular to a kind of portable food detection sampling
Servicing unit.
Background technology
" bread is the staff of life ", diet are the main ways that human body draws the nutrition depended on for existence and energy from external environment
Footpath, it is basis and the performance of vital movement；" eat with An Weixian ", the safety of food is not only related to the existence of people and body is good for
Health, and it is related to the quality and the ups and downs of nationality, a national reputation is also directly influenced in international trade contacts.China
There are 23 provinces, wherein 14 coastal, east and southern mainland coastline are up to the waters of km more than 1.8 ten thousand, inland sea and Bian Hai
Area ten thousand sq-km about more than 470, proportion of the aquatic products in food is even more constantly growth in recent years, and the safety of aquatic food is also
It is taken seriously.
Be contaminated in the growth waters of aquatic products or breeding process in the illegal additive prohibited using country or
Using the additive of excess, the risk that can all directly contribute aquatic food steeply rises.It then becomes necessary to strengthen aquatic food
Sampling supervision, irregularly carries out the work of aquatic products food security sampling Detection, progressively expands aquatic products food sampling inspection covering
