Directive No. (5/98) on Water and ice standard for fish industry

3 I Government of the Union of !Vlyanmar Ministry of Livestock and Fisheries DEPARTMENT OF FISHERIES DIRECTIVE No. (5/98) August 3, 1998 ln exerccise of the powers. conferred by Section 23 of the Myanmar Marine Fisheries Law 1990, the Director General of the Departmet ofFisheries hereby issues the following Directive for quality of water & ice standard for fishery industry. Water and Ice Standard for Fishery Industry I l This Directive concerns standard for water intended for human consumption. 1.2 For the purpose of this Directive, water intended for human consumption shall mean all water used (or that purpose, either in its orginal state or after treatment regardless of orign, (i) whether supplied for consumption, or (ii) whether (a) used in food production of fish and fishery products undertaking for the manufacture, processing, preservation or marketing of products or substances intended for human consumption and; (b) affecting the wholesomeness of the fish & fishery products in its finished fonn. 2. 1 Any licence-holder for the processing of fish and fishery products shall abide by this Directive as one of the conditions of the licence. · 32 2.2 On violation of the any terms or conditions of the Direct+ive, criminal action may be taken under Section45 of the Ivlyaruna Marine Fisheries Lav,1 1990 and the licence-holder may also be liable to suspension, revocation, termination and cancellati'on of the licence under Section 24 of the said Law Sd xx Soe Win Director General Department of Fisheries.
