1、农村集体聚餐食品安全培训资料一、食品卫生“五四”1、四不：采购员不进，保管员不收，食品加工员不做，服务员不卖腐败变质的食物。2、四隔离：生熟隔离，成品与半成品隔离，食品与杂物药物隔离，食品与天然冰隔离。3、四过关：一洗、二刷、三冲、四消毒。4、四定：定人、定物、定时间、定划片分工、包工负责。5、四勤：勤洗手、勤俭治家、勤洗澡理发、勤洗已脏工作服。二、清除蔬菜上残留农药的几种简易方法1、浸泡水洗法：蔬菜污染的农药品种主要有机磷类杀虫剂，有机磷杀虫剂难溶于水，此种方法仅能除去部分污染的农药，但水洗是清除蔬菜水果上其他污物和去除残留农药的基础方法。主要用于叶类蔬菜。一般先用水冲洗掉表面污物，然
2、后用清水浸泡，浸泡不少于10分钟，果蔬清洗剂可增加农药的溶出，所以浸泡时可以加入少量果蔬清洗剂，浸泡后要用流水冲洗2—3篇。2、碱水浸泡法：有机磷杀虫剂在碱性环境下分解迅速，所以此方法是有效地去除农药污染的措施，可用于各类蔬菜瓜果。方法是先将表面污物冲洗干净，浸泡到碱水中(一般500m1水中加入碱面5g—10g)5一15分钟，然后用清水冲洗3—5遍。3、去皮法：蔬菜瓜果表面农药相对较多，所以削去外皮是一种较好的去除残留农药的方法。professionalengineer1,eachequippedwiththeprofessionaltechnician1,2technicians,ca
