In the present setup of the world, we are very particular about hygiene and cleanliness. But have you ever given considerable thought to the quality of cleaning agents taht you have been using all this time? Are they safe? Are they up to the required quality standards?
Well, if you have not been considerate, it’s high time that you should be. As the first precaution, ensure that your chosen product has undergone an en 1276 disinfectant test.
The concerns related to bacteria and infections have risen more in the post-pandemic scenario. Across the industries, we can see mandatory norms for testing and sharing the results with the general public. The testing norms related to the food and beverages industry have gained more attention. Surface cleaners and disinfectants in the food industry are chosen more carefully than ever.
Here is why:
Several different species of bacteria can be found on food preparation surfaces and equipment that come into contact with food. A good, efficient disinfectant is necessary to eliminate a wide range of germs on a surface.
Several disinfectants promise to destroy 99.9% of bacteria. Although this appears to be very promising, it does not guarantee the validity of that product.
Disinfectants should be evaluated using Standard Test Methods to show their efficacy. One of the most common methods for such tasks is the en 1276 disinfectant test.
The cleaning solutions satisfy all of the appropriate criteria. It is especially true in this industry because cleanliness is crucial, and tight restrictions are in place. The disinfection process in your surroundings necessitates the selection of a suitable product and a careful thought process.
What is the test about?
Antimicrobial products are designed to control and combat certain harmful bacteria. Primarily, a suspension test is required to determine if a chemical disinfectant or antiseptic exhibits bactericidal action. This test is used in various industries, including food, domestic, and institutional.
This test is also applicable in areas and situations where disinfection is medically indicated and excludes living tissues except for hand hygiene such as hydroalcoholic gels.
The major challenge lies with developing antimicrobial solutions that destroy & limit the development of bacteria. The effect of these substances is also an issue because of the rising safety norms regarding quality & efficacy. However, you may analyse your product’s bactericidal activity. Doing so might help you to explore the results that are claimed by marketing campaigns of your product provider.
Conditions of en 1276 disinfectant Test:
- The standard specifies that the parameters should be observed and aligned with the items under observation. It holds particularly true while evaluating things in the food, industrial, and household sectors for the general process of disinfection. Besides, there should be a proper check for the microorganism, temperature, contact period, and interfering substances.
- It is essential to assess the antibacterial activity of the product. The obligatory list of microorganisms must be utilized in the test. It is generally referred to as the test microorganism. The necessary microorganisms represent all bacteria in a group. So, it has to be made sure that the correct set is chosen. The results might greatly be affected if there is any discrepancy in this step.
- Next comes the temperature. Whenever microorganisms are considered, the temperature has a significant role to play. The temperature at which the test must be performed is the test temperature. In general, disinfectants are less efficient at low temperatures than higher temperatures. Although, this condition might vary with different organisms.
- Contact time is also an essential factor for the effectiveness and the quality of results. It refers to the minimal amount of time a product needs to be in touch with bacteria. It is to be made sure that the En 1276 disinfectant test time & contact period are adequate.
- The “interfering material” refers to a substance utilized in the test to represent pollutants that may co-occur with bacteria in the real world. The health of this material should be as per the guidelines stated under the norm.
The role and impact of bacteria:
The presence of bacteria does not always imply infection. The susceptibility and the infectious dosage are also crucial. The susceptible people, like kids, old and unwell, are more vulnerable to infections.
Certain bacteria may cause illness even if just 100 cells are introduced into incisions. The slightest difference can also be significant. For example, a surface containing a million bacteria would still have a thousand bacteria after being treated with a chemical that kills 99.9% of germs if a substance that kills 99.999 per cent of bacteria was applied to the surface.
The pace of development slows when conditions are less than optimal, such as lowering the temperature or drying the surface. That is why disinfectants in various environments are tested and simulated to know how they would be used in the real world.
The following bacterial strains are used for evaluating the bactericidal activity of disinfectants/antiseptics using the En 1276 disinfectant method:
- Pseudomonas aeruginosa bacteria.
- E. coli
- Staphylococcus aureus bacteria.
- Microorganisms like Salmonella & Enterobacter can also be included.
A suitable chemical might be added to the testing scope as required by the standard testing method. It comprises two conditions- “clean” and “dirty” conditions. These are created by varying the concentration of bovine albumin in a solution. As a result of this activity, the tested product’s actual conditions for usage may be replicated.
As per standard practice, the combination is held at ambient conditions for a specific time. The test sample is introduced to the bacterial suspension by diluting as required. Following adequate dilution-neutralization of the mixture, the product’s bactericidal activity is tested by counting surviving organisms and estimating bacterial reduction.
There are numerous ways to determine surface disinfectants’ antimicrobial effectiveness and cleanliness. However, standard tests like en 1276 disinfectant tests ensure the safety of materials and surfaces. However, the requirements may differ depending on the surface and the conditions of the assessor.
The test conditions can be modified as per the client’s requirements or the requirements of the study.
