　　UK - Isotope testing of pork and pork products for their origin is being stepped up by AHDB Pork from once a quarter to monthly.The testing uses SIRA (Stable Isotope Reference Analysis), an innovative isotope technology which compares retail and processed pork and pork products against a library of pork samples from known locations built up over a number of years.Analysing the ratios of the four main stable isotopes contained in pork means the probability of the sample coming from the UK can be determined.AHDB Pork strategy director Mick Sloyan said: “The focus to date has been on fresh pork in supermarkets. Last year, we extended it to bacon and pork used as a raw material in sausages and ham.

　　英國(guó)農(nóng)業(yè)及園伊⒅(AHDB)采用同位素加強(qiáng)豬肉和豬肉制品來源檢測(cè)，頻率從一個(gè)季度一次到一個(gè)月一次。測(cè)試采用穩(wěn)定同位素對(duì)照分析法(SIRA)。SIRA是一種創(chuàng)新同位素技術(shù)，用零售、加工的豬肉和豬肉制品與存在文庫(kù)經(jīng)過多年采集已知來源的豬肉樣品對(duì)照。分析豬肉中四種主要同位素的比例，就能知道樣品來自英國(guó)某地的約摸性。英國(guó)農(nóng)業(yè)及園伊⒅(AHDB)豬肉策略總監(jiān)米克斯隆(Mick Sloyan)說：“主要數(shù)據(jù)來自超市里的清新豬肉。去年，我們把范圍擴(kuò)大到培根和用豬肉制作的火腿和香腸”。
