There are many different types of bacteria in the environment. Most frequently occurring environmental bacteria are those usually considered as non-pathogenic or harmless. Some bacteria, however, are a health hazard posing serious health threats.
Besides air culture testing, it maybe required to analyse water, solids, and surface samples for any specific bacteria.
Bacteria Inspection and microbiologic sampling is usually carried out in certain situations:
Disease causing microorganisms or pathogens are spreading disease directly among humans. In some industries like healthcare or food processing/preparation, bacterial contamination is more common and serious. However, homes and workplaces can also be contaminated with certain species of bacteria such as Enterobacteria, Pseudomonads, Staph. aureus, Streptococcus species and B. cereus. Most of these are potentially pathogenic and health hazards.
It is important to identify any lingering bacteria using approved sampling techniques, as different bacteria have different survival life span. Bacteria is transferable within an environment and many studies have shown a greater association between pollution and health problems. There is also evidence of a link between the development of respiratory and allergic symptoms due to exposure from indoor microorganisms.
Pathogen-associated molecular patterns (PAMPs) are the dominant microbial components linked to human health. These are molecules such as endotoxin and lipopolysaccharide, flagellin and glucans which are associated with groups of bacteria or fungi microbes. These may influence the human immune system responses, interact with airway or irritant receptors or have toxic effects.
With NCPI’s bacteria sampling, bacteria analysis and bacteria reporting, we can help you understand the level of bacterial contamination, the impact of the type of bacteria present in your home or facility and how they can be managed to minimize the risk.
In indoor environments, bacteria can be found on surfaces or in the air. For surfaces, sampling of all areas especially all high-contact areas should be done. Air and environment sampling involves testing in areas like cooling towers or heat rejection equipment used in air conditioning and industrial cooling water systems. This is mainly due to the risk for widespread circulation.
Surface samples are most commonly taken through bulk samples, swab samples, and tape samples. Air samples are taken using specially designed equipment to meet the differing measurement requirements as well as the type of information desired. They can be self-contained units or those with additional auxiliary equipment.
The Bacteria Inspection process includes formulating and implementing a defined, multidisciplinary protocol for sample collection and culturing, submitting a report of the analysis and interpretation of results using scientifically determined or anticipatory baseline values for comparison.
Having professional bacteria sampling, bacteria analysis and bacteria reporting done for your property helps in identifying any specific areas/sources of contamination and in assessing the level of hygiene of the environment. NCPI provides Bacteria Inspection reports that will assist the property owners as well as remediation professionals with an insight into the level and type of remediation needed to be undertaken. The reports also help in later assessing the effectiveness of cleaning and disinfection processes followed. Our bacteria inspection reports range from specific targets or total bacteria counts to species or genus identifications and more.
Microbiologic sampling of air, water and inanimate surfaces for bacteria is a specialised and time-consuming process, defined by many variables in protocol, analysis, and interpretation. It is therefore best left to professionals with knowledge and expertise in the field of bacteria inspection. The expert team at NCPI can effectively handle any of indoor environmental issues like bacteria inspection for domestic and commercial buildings. Our highly experienced and qualified hygienists will handle the bacteria inspection, sampling, analysis and reporting. Contact us today to discuss your specific requirements.
