Operating procedures for the detection of the limit of microorganisms in oral liquid
1. ** Controlled oral liquid bottle **: - Take 10 vials randomly, suck up 5ml of sterilized water with a straw, add it into the bottles, cap them, shake them for 1 minute, pour the sterilized water into the sterilized triangular flasks, shake them up to obtain the test solution, and then carry out the test according to the relevant methods for the test of the limit of microorganisms (such as QOS - 084, Method for the Limit of Microorganisms). The total number of bacteria and mold should be less than or equal to 100/bottle, and no E. Coli should be detected. 2. ** Syrupy bottle (also a type of oral liquid bottle)**: - Take 10 vials of syrup, respectively suck 10ml of sterilized water with a straw and add it into each bottle. Cover the bottle cap and shake it for 1 minute. Then pour the sterilized water into a sterilized triangular flask and shake it well to obtain the test solution. Then, carry out the test according to the relevant methods for the limit test of microorganisms (e.g. QOS - 084 Method for Limit Test of Microorganisms). The total number of bacteria and mold should be less than or equal to 100/vial, and no E. Coli should be detected. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to write the results of the collection of microorganisms on the surface of the organism?
The writing of the collection results of the microorganisms on the surface of the organism should include the following contents: ** 1. Basic Information ** 1. ** Information of sample ** - Make clear the name of the object to be collected, such as the table top, door handle, or the surface of a medical device. - For samples with special requirements, such as medical devices, the use, type, and other relevant information should be indicated (for example, whether it is an invasive treatment telescope or an telescope that contacts damaged skin and mucus membranes, etc.). 2. ** Information about the Sampler ** - Record the name or number of the person who took the sample. - The sample time was accurate to the year, month, and day. ** II. Microbiological test items and results ** 1. ** Species of Microorganisms ** - List the types of microorganisms detected, such as bacteria, fungi, viruses, etc. For bacteria, it was necessary to be specific to the species, such as S. aureus, E. Coli, and the spores of B. subti. niger, etc. For fungi, it was necessary to be specific to the species, such as C. candida, A. niger, etc. - If multiple microorganisms are tested, they should be listed according to the relevant standards or in the order of actual testing. 2. ** Number related ** - The number of microorganisms was given. For bacteria, it could be expressed in colony forming units (ifu). For example, the surface of the object was judged to be qualified or unqualified according to the hygiene standards: Class I, Class II <5Cu/cm <2>, Class III, Class IV <10Cu/cm <2>, etc. If it was the number of microorganisms detected in a certain amount of samples, the sample size should also be clearly stated, such as the number of microorganisms per milliliter of sample or the number of microorganisms per square centimeter of the surface of the sample. 3. ** Test Item Speciality ** - If it is a disinfection product's microorganisms test, it should be in accordance with the standards of the relevant disinfection products. For example, the type of surface disinfectant machine should be in accordance with the requirements of the standard WS628 - 2018 "Health and Safety Evaluation Requirements for Disinfection products" and the "Disinfection technical specifications" 2002 edition. For the surface disinfectant machine for different purposes, the results should be recorded according to the specified inspection items. For example, if the label and instructions of Class I disinfection products indicate that they are used for high-level disinfection of medical devices and supplies, the results of the spore killing test of the mutant of B. subti. niger should be recorded; if they are indicated to be used for disinfection of the surface of sanitary ware, the results of the quantitative disinfection test of candida Albicans should be recorded. ** 3. Judgment result ** 1. The collection results were judged according to the pre-set hygiene standards or standards related to the purpose of the test. For example, if the number of microorganisms on the surface after disinfection was within the specified range, it would be judged as qualified for disinfection, and if it exceeded the specified range, it would be judged as unqualified. 2. For special circumstances, such as the detection of rare microorganisms or the detection of microorganisms with special risks (such as the detection of drug-resistant bacteria, etc.), special instructions should be made in the judgment results. ** 4. Other supplementary information ** 1. If there are special circumstances during the collection process, such as the special conditions of the sample environment (high temperature, high humidity and other environmental factors that may affect the survival of microorganisms), or the special state of the sample itself (such as the possibility of being contaminated, special coating on the surface, etc.), a brief explanation should be made in the results. 2. If it involves subsequent treatment suggestions, such as the need to re-disinfect or further test the list of microorganisms, it can also be indicated in the results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
