  • Georgia Spore Testing Requirements for Tattoo/Body Art

    Georgia Spore Testing Requirements for Tattoo/Body Art

    <- Back to Learning Center

    In Georgia, the requirements for autoclave spore testing in tattoo studios are regulated by the Georgia Department of Public Health (DPH) and the state’s rules for tattooing. Autoclave spore testing is a critical practice to ensure that autoclaves are effectively sterilizing equipment used in tattooing procedures.

    Governor Kemp signed into Law Senate Bill 214 which directs the Georgia Department of Public Health to adopt statewide Body Art regulations including the permitting of body artists. On March 6, 2023, the Department passed Chapter 511-3-8, Rules and Regulations for Body Art. Implementation of the Chapter will begin on October 6, 2023, six months after the effective posting date. Existing artists and studios will be given until October 6, 2024, a 12-month period, to meet the new requirements.

    Woodhouse Laboratories can help you meet your testing requirements and comply with the regulations put into place by Governor Kemp.

    Spore tests shall be used at a minimum frequency of every 40 hours of operation of the
    autoclave but not less than on a monthly basis unless the manufacturer specifies more frequent
    monitoring. Records of the results must be kept for a minimum of three years. An independent
    commercial testing laboratory contracted by the permit owner or body artist, or both shall
    perform biological spore testing of the autoclave. A provision shall be included in the contract
    with the commercial testing laboratory requiring the body art studio to notify the Health
    Authority of any failure of the autoclave to eradicate all living organisms, including spores.


    Upon notification of a positive microbiological monitoring report, the autoclave shall be
    immediately checked for proper use and function and the permit owner shall cease use of the
    autoclave immediately upon receipt of the positive report. Any items remaining bagged after
    sterilization must be reprocessed and sterilized by a medical-grade autoclave approved for use
    prior to return to service. A negative biological test and passing a Class 5 integrating indicator
    must be achieved before the autoclave can be used again and the studio is reopened. The studio
    shall have the option to obtain a properly functioning sterilizer with a negative biological report
    in order to remain open or if the studio has more than one autoclave in operation, they may be
    given approval to remain open. The Body Art Studio’s standard operation procedure should
    include an emergency plan should an autoclave failure or malfunction occur.

    For detailed guidance, tattoo studio owners should consult the Georgia Department of Public Health’s rules or local regulations regarding body art establishments.

  • Understanding the Difference Between Single Strip and Multi Strip Test Kits for Sterilization Monitoring

    Understanding the Difference Between Single Strip and Multi Strip Test Kits for Sterilization Monitoring

    <- Back to Learning Center

    A single strip test kit and a multi strip test kit serve similar purposes in sterilization monitoring but cater to different needs based on the scale and requirements of the user.

    Here at Woodhouse Laboratories, we recommend ordering one test kit per sterilizer, as our envelopes are custom printed with your sterilizer details. This ensures that each test is specifically tailored to the sterilizer being monitored. We do not recommend using a multi strip test kit to test multiple sterilizers, as it could lead to confusion in tracking and maintaining the correct data for each individual unit.

    Single Strip Test Kit:

    • Design and Use: The single strip test kit includes one test strip and one control strip per envelope. It is primarily designed for routine sterilizer checks, ideal for small to medium-scale operations or those with standard sterilization needs.
    • Regulatory Compliance: It meets compliance regulations across all 50 states, making it a widely accepted choice for ensuring that sterilization processes are in line with health and safety standards.
    • Popularity: This is the most popular product due to its simplicity, and ease of use.
    • Functionality: The test is effective for checking the sterilization efficiency in individual sterilizer cycles, offering a quick result for each test.

    Multi Strip Test Kit:

    • Design and Use: The multi strip test kit includes two test strips and one control strip per envelope, and is typically used in larger industrial autoclaves or by clients who need to test multiple areas within the sterilizer chamber.
    • Comprehensive Monitoring: This kit provides a more thorough assessment of the sterilizer’s performance by allowing users to test different locations within the chamber. This can reveal potential inconsistencies or issues in the sterilization process that may not be detected with a single test strip.
    • Application: It is ideal for clients running very full loads in their sterilizers or those who want to monitor the functionality across a larger surface area or more complex sterilization setup.
    • Benefit: The multi-strip kit provides a more comprehensive view of how the sterilizer is functioning, making it a valuable tool for industries that require high-volume or complex sterilization processes.

    In summary, while the single strip test kit offers simplicity and regulatory compliance for standard sterilization checks, the multi strip test kit is better suited for larger operations or situations where detailed monitoring of different areas within the sterilizer is needed.

  • Understanding the Differences Between Sanitization and Sterilization

    Understanding the Differences Between Sanitization and Sterilization

    <- Back to Learning Center

    Sanitization and sterilization are two terms that are often used interchangeably, but they actually refer to two different processes. Both are used to clean and disinfect surfaces, but the level of cleanliness achieved is different.

    Sanitization refers to the process of reducing the number of harmful microorganisms on a surface to a safe level, as determined by public health standards. This is typically achieved through the use of chemicals or heat. Sanitized surfaces are considered safe for human contact and use, but some microorganisms may still be present.

    Sterilization, on the other hand, refers to the complete elimination of all microorganisms, including bacteria, viruses, and spores, on a surface. This is typically achieved through the use of chemicals, heat, or radiation. Sterilized surfaces are considered completely free of any living organisms.

    In general, sanitization is used in most everyday cleaning situations, such as cleaning kitchen counters or bathrooms. Sterilization is usually reserved for medical settings, such as operating rooms and laboratories, where a higher level of cleanliness is required to prevent the spread of disease.

    It’s important to note that both sanitization and sterilization require regular maintenance and may not be effective against certain types of microorganisms, such as certain types of bacteria that are resistant to antibiotics.

    In conclusion, sanitization and sterilization are two different processes that are used to clean and disinfect surfaces. Sanitization is used for most everyday cleaning situations, while sterilization is reserved for medical settings where a higher level of cleanliness is required. Both require regular maintenance and may not be effective against certain types of microorganisms.

  • Infection Control in Tattoo Studios: Essential Practices for Ensuring Safe and Sterile Procedures

    Infection Control in Tattoo Studios: Essential Practices for Ensuring Safe and Sterile Procedures

    <- Back to Learning Center

    Proper infection control in tattoo studios begins with the selection of safe and sterile equipment. All needles, tattoo machines, and other tools must be sterile, and must be properly disposed of after each use. Additionally, the studio must be kept clean and free of clutter, with surfaces regularly disinfected and cleaned. The tattoo artist must also follow strict hygiene practices, including washing their hands before and after each tattoo and wearing gloves throughout the procedure. They should also be aware of the signs of infection, such as redness, swelling, and discharge, and take appropriate action if they occur.

    Another important aspect of infection control in tattoo studios is the management of blood and other bodily fluids. The studio must have a policy in place for dealing with any spills or splashes, and all surfaces that come into contact with blood or other bodily fluids must be properly disinfected.

    Proper sterilization of equipment and tools is also crucial for preventing infections. Using an autoclave is a very common method for sterilizing equipment in tattoo studios, it’s important to ensure the autoclave is properly calibrated and maintained, and that regular spore testing is conducted to ensure the equipment is working effectively.

    There are over 21,000 tattoo studios throughout the 50 states. 40 states + DC require studios to perform monitoring of their sterilizer. Most of those require that such testing be performed by a 3rd party. Insufficient monitoring means the tattooist jeopardizes both their license and the health of their clients.

    Most states require monthly testing, but there are a few exceptions. Missouri and Ohio have the strictest laws, both requiring weekly monitoring of sterilizers in tattoo facilities, which puts them on par with most state’s dental regulations. Florida and Kansas require only quarterly testing (every 3 months). State regulations are subject to change with political tides, and many local municipalities have their own regulations, so always review your local laws and codes to verify your current regulations.  To see your state’s requirements, check out our map of all state’s tattoo regulations which includes links to regulatory documents.

    Finally, it’s important for tattoo studios to have a clear and detailed infection control policy in place. This policy should be provided to all clients and employees and should be reviewed and updated regularly. In conclusion, infection control is an essential aspect of tattooing. Proper selection and sterilization of equipment, hygiene practices, management of blood and other bodily fluids, and the implementation of a clear infection control policy are all crucial for ensuring safe and sterile procedures in tattoo studios.

    Do I really need to test?

    Just because a state doesn’t require testing does not exempt a tattoo studio from sterilizer monitoring.  Many municipalities have their own regulations which are more strict and/or a higher frequency than those of the state level agencies.  For example, the state of Maryland has no regulations regarding tattoo studio sterilizer monitoring but Allegany and Calvert county each require monthly testing.  So always check with your county and city governments health department or equivalent agency to verify that you are in compliance.

    What about disposables?

    It is important to remember that 21,000 tattooists doesn’t mean 21,000 sterilizers.  Today, most tattoo studios use only pre-sterilized disposable equipment, so a sterilizer may not be necessary. However, most tattoo studios do not limit their services exclusively to ink – many also perform piercings, which means they still need a method of sterilizing body jewelry.


    If you are a tattooist, or a patron of a tattooist, and you have any questions about your local regulations, you can always call or email the experts Woodhouse Labs for a free consult.

  • Understanding Autoclave Spore Test Strips: A Guide to Ensuring the Effectiveness of Your Sterilization Equipment

    Understanding Autoclave Spore Test Strips: A Guide to Ensuring the Effectiveness of Your Sterilization Equipment

    <- Back to Learning Center

    Autoclave spore test strips are small, self-contained units used to test the effectiveness of an autoclave in sterilizing equipment and materials. These test strips contain a specific type of bacteria, usually Geobacillus stearothermophilus and Bacillus atrophaeus/subtillus, that is known to be highly resistant to heat and typically used as a biological indicator of sterilization.

    The process of using autoclave spore test strips is relatively simple. First, the test strip is placed inside the autoclave along with the equipment or materials to be sterilized. The autoclave is then run through a complete sterilization cycle, including exposure to steam, and drying phase.

    It’s also important to ensure that the test strips are stored and handled properly to prevent contamination. They should be kept in a cool and dry place, away from direct sunlight, and should be used before the expiry date.

    In conclusion, autoclave spore test strips are an essential tool for ensuring the effectiveness of an autoclave in sterilizing equipment and materials. Regularly using these test strips, proper storage and handling, and following the manufacturer’s instructions can help ensure that the autoclave is working effectively and that equipment and materials are properly sterilized.

  • Now Offering New Service: Population Verification Tests

    Now Offering New Service: Population Verification Tests

    <- Back to Learning Center

    Woodhouse Laboratories offers more than standard presence/absence testing of biological indicators. We are also offer Biological Indicator Population Verification tests. Population verification is useful for:

    • Verifying that your biological indicator meets manufacturer’s claims of the population inoculated on the carrier
    • Initial autoclave verification – determine lethality rates and D-values
    • Research projects – Need to know the quantity of bacterial spores remaining after a sterilization cycle? Population verification provides quantitative data.

    Background

    The Biological Indicator Population Verification test determines the number of spores on a biological indicator (BI) and is used to enumerate survivors from a sterilization process to determine lethality rates and D-values. A count ensures the count recovered meets manufacturer’s claims of the population inoculated on the carrier.

    Population enumeration is important because it provides quantitative data, whereas a BI sterility test only provides growth/no growth results.

    These are tested in accordance with USP <55> Biological Indicators – Resistance Performance Tests or manufacturer’s instructions.

    Method Description

    When performing Biological Indicator Population Verification testing, BIs are macerated using sterile glass beads. The macerate is then heat shocked, and the suspension is diluted to yield colonies in the range of 30–300 colony-forming units (CFU) and then plated. Other methods can be used as required. All results are compared against an untreated spore strip or BI control.
