How does the kitchen distinguish between clean disinfection and sterilisation?

The primary answer is whether the contamination has been removed to the required level, the disinfection is concerned with the harmless treatment of pathogenic microorganisms, and the sterilization is aimed at the removal or extinction of all microorganisms in the vector. The three cannot be synonymous. Kitchen equipment is marked as steam, hot wind or dry, a description of the treatment method or function, and cannot be upgraded by name alone to have been sterilized.

These differences directly affect procurement and day-to-day operations. Staff may skip pre-treatment if they consider disinfection to be the removal of the residue, and may make claims that do not correspond to the actual use and authentication capacity if the purchase form describes the general sterilization task as disinfection. The precise use of words is not to reduce health requirements, but to match mandates, methods and evidence.

The three words go back to the same Chinese term.

The Sterilization Professional Terminology WS/T 466-2014 applies to the use of terms in the disinfection professional field. The difference is summarized below after checking its articles 3.25, 3.38 and 3.18; this is not an evaluation of the capacity of a particular equipment. [1] As of the time of the visit, the National Standard Information Public Service Platform (NSPSP) had included the recommended industry standard in its current form, with an implementation date of 1 February 2001. [2]

Terms	Brief description of the core meaning	The kitchen understands the boundaries to be kept.
Cleaning	Remove contamination from the articles.	It doesn't look like all target microorganisms are meeting the requirements.
Disinfection	Sound treatment of pathogenic microorganisms in the media	We can't replace all microbes automatically.
Bacillus eradication	Kill or remove all microorganisms in the media	The method and authentication required to match the sterilization mission is not presumed by the mode name

Cleaning here does not involve only large pieces of debris that are visible to the naked eye, nor is disinfection uniform equal to “a percentage”. Specific objects and application requirements determine what needs to be addressed and confirmed; the terminological criteria give a concept and are not responsible for the selection of temperature, time, dose or complete equipment for the catering project.

Nor does the goal of sterilization mean that an advertisement can prove that the object is permanently sterile thereafter. The conditions of exposure, packaging and preservation after processing are another stage that must be controlled. The name of a process is written on the cabinet door and does not leave the equipment that was recontaminated after removal in its original state.

The words of the English article cannot be removed from their test terms.

Hobart's source is the sanitiration and stetilization of commercial dishwashers in the context of the epidemic, which concerns the certification of United States dishwashers and the corresponding test expression. [3] Reading such material should first identify which equipment, which criteria and which object it talks about, rather than seeing the approximation of English as a direct replacement for a Chinese qualifying statement for a domestic project.

In particular, the results of testing of the original brand machine cannot be moved to another company's equipment, nor can the results for certain representative objects be extended to “effective for all pathogens”. The Epidemic Note at the time of the publication of the source is not a sufficient basis for the effects of today ' s product; any statement in the article about the transmission of disease or the handling of protective supplies should not be translated into a kitchen work directive without a proper verification.

Chinese procurement or training materials are better suited to indicate whether the project requires cleaning, disinfection or other clear treatment objectives, and then to refer to the applicable documents. English terminology can be retained for retroactive purposes, but it cannot be used to avoid the Chinese mission boundaries. In the case of a conflict of information terms, the meaning and scope should be checked against the issuer, rather than the word that sounds more effective.

What level does a device describe?

The first level is the manufacturer ' s statement. For example, the official information indicates that a model has a steam treatment program and that this is the manufacturer ' s description of the function of the model. To check the model and version, it is not possible to replace the functionality of another piece of equipment in the same series.

The second tier consists of reversible design or operational parameters such as rated power under corresponding conditions, control setting or program options. Parameters describe a part of the equipment ' s design and range of operations, but the object of measurement may be the position of the cavity, medium or sensor, which does not necessarily equal the actual experience on the surface of each meal.

The third level is evidence of the effect. It needs to know the subjects, methods, loading, procedures, evaluation indicators and range of results. A report covers only the test conditions listed and does not automatically cover any material, unlimited loading or any on-site operation. The three layers can be linked, but the middle conditions cannot be omitted to jump directly to the final conclusion.

Assuming that one page of information only describes a “heating programme”, the conservative expression is that the facility publicly provides the function. It is not possible to write on this basis that “the whole meal is sterile without pre-cleaning”. In the latter sentence, three claims for ex-treatment exemptions, unlimited object extension and sterilization were added, and none of the original functional names were proven.

The percentage needs the denominator and the range of results.

Assuming that, in a given teaching experiment, the number of available persons for a specified object has been reduced from 10,000 to 100 and is 99 per cent at a simple reduction rate, it describes a change in the number of objects under these conditions, which does not mean that all objects have the same results, let alone declared the eradication. This is just a mathematical example, not a product test or a qualifying limit.

A distinction should also be made between non-existent tests and absolute non-existence. The test methods are subject, scope and capacity limitations, and only their methods and samples are presented accordingly. There is no description of sampling and methods, and the word “undetected” in the separate column does not allow the reader to know what the measure is or to judge other locations and subsequent batches accordingly.

Power figures, temperature displays and percentages appear to be accurate, but precise figures do not guarantee the completeness of the reasoning. Procurement staff should ask which task the outcome was, on which basis it was based, rather than just who had more publicity than who. There is no evidence against it, and it should be deleted or narrowed and not “normally” “in theory” to make unknown packagings available.

The whole path of the utensils cannot be swallowed by one word.

The Code of Practice for Food Safety in Catering Services sets out the requirements for cleaning and disinfection, asphalting or drying, and cleaning of meals. [4] Corresponding meals used for access to directly imported foods need to be processed as required; not a cabinet light can replace full confirmation.

The after-use tableware shall be removed and cleaned, as applicable, to allow the material to be processed in conjunction with the load, after which appropriate water treatment and specialized cleaning shall be required. The fixed temperature and time of each equipment share are not provided here, and the actual procedures correspond to the equipment, method and effective description. Even if the equipment integrates several steps, the user needs to know whether the task of each step is actually included in this machine procedure.

Decontamination is completed, and if it is removed and the dirty basket is returned without the corresponding treatment, the problem occurs at the back end of the contact; if the device is entered with the residue, the problem arises at the front end. Neither can be solved simply by rewriting “sterilization” as “sterilization”. Conversely, the requirement of cleaning cannot be understood to mean that the equipment will never be opened, and that normal access requires proper protection and hygiene.

How do you change the script more precisely?

“So decontaminated” should be removed from the description of the permissible method used, the steps completed and how to confirm; if only the cleaning is done, it is written clean. “High temperature equals sterilisation” should be returned to the actual process and effect basis and the conclusion cannot be retained by a single display of temperature. The words “all devices shall be applicable” should be replaced by the scope defined by actually permitted materials, structures and uses.

These examples do not write for specific products, nor do they provide new guarantees of effectiveness. The main language of the description should be clear: whether it is a public description by the manufacturer, a test report, or a proper on-site record of this instalment. The subject matter is different, and the subject matter of the evidence is different so that the reader can judge which are functional information, which are conditions for use and which are the confirmed results.

What is really needed in the kitchen is not the most effective word, but the name of the mission that can be correctly carried out. Cleaning, disinfection and sterilization have different meanings, and no word can replace pre-treatment, correct operation and subsequent protection. To clarify this relationship, procurement and shifts do not leave a gap in the different understanding of the same word.
