In particular, the spread of enteric viruses, e.g. Perform the analysis as per the current version of purified water specification. Sampling Procedures for Drinking Waters 1 PURPOSE This standard operating procedure outlines details for collection of drinking water samples for chemical, microbiological and radiological analysis. Phase 2 follows the determination of data validity and investigates the water system and all potentially affected lots of products. The precautions taken to avoid contamination must be such that they do not affect any microorganisms that are to be revealed in the test (water analysis). 4.1.16 Again collect the swab sample and repeat procedure following Point 4.1.1 to 4.1.13. Annexure-2: Sampling Schedule of Purified Water. Water Sampling Procedure (with reference to ISO 5667 Part 5) (A) Assessment of Sampling Location Please take note of the conditions of the environment, sampling taps and pipes at the sampling location. <>>> Noroviruses, are repeatedly related to poor water quality (… SUPPLY … Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. 3 0 obj Correct sampling procedures as instructed by international standard protocols must be adhered to; Routine microbiological testing of drinking water supplies, recreational waters, and environmental waters is essential for the protection of public health ; Programme of testing. drinking water samples and handling of sample preservatives. PROCEDURE FOR MICROBIOLOGICAL MONITORING OF WATER. for validated time. Then remove the sterile strip from the bottle. If the immediate analysis is not possible to acidify the sample with a 2-3 drop of 2.0 M HCL and store the sample under refrigeration at 2 to 8ºC. Close the bottle with a cap and wrap the neck with aluminum foil and Sterilize the bottle at 121 ºC (15 lbs.) Where potable (drinking water) water is stored, BS8558:2015 sets out a regime where 6 monthly microbiological activity is measured. 6.0 PROCEDURE FOR ANALYSIS OF WATER SAMPLE: Carry out the determination under conditions designed to avoid extrinsic microbial contamination of the water sample for the analysis. Chemical analysis: 2. This Standard Operating Procedure is applicable to the Microbiology Department. The final summary report shall be prepared at the end of the Year. 1 minute. SAMPLING FOR MICROBIOLOGICAL ANALYSIS In case of laboratory analysis for microbiological purpose, following guidelines are adopted to collect representative water samples: Sample Bottles Pre-sterilized sampling bottles of 200 ml capacity made of pre-sterilized disposible/autoclavable plastic, or good quality soda / borosilicate glass. Vinlab supplies 100ml sterile plastic bottles. Food Safety and Inspection Service: •Sampling methods •Assessing sampling plans and testing methods •Method validations and laboratory quality assurance •FSIS testing programs, methods and pathogen-specific issues to consider •Industry testing activities 2 Today’s Presentation. Aseptic Technique for Microbiological Testing. x��[mo�6� �Aw�X_DIE�q�;�:M � Collect your water sample early in the week – Monday to Thursday –to give enough time to get to the laboratory and to be analyzed within 24-30 hours. A sample volume of 250 mL should be sufficient for Total coliform, Faecal coliform, E. coli and Heterotrophic plate count WATER ANALYSIS SAMPLING PROCEDURES Microbiological samples: Microbiological samples should be collected in sterile plastic or glass bottles which Vinlab supplies. Close the container immediately and record the sampling time.
