New Laboratory Registration System / Campus Biosafety Stewardship

In the wake of widely publicized news of potential exposures and mishandling of infectious agents involving federal laboratories, the National Institutes of Health (NIH) and other federal agencies, are urging all U.S. laboratories working with biohazardous materials to assess and strengthen their biosafety standards and practices, and to reexamine policies, procedures, training, security and oversight of the use and storage of infectious agents.

To facilitate the stewardship of laboratory operations and safety at Stony Brook, the Department of Environmental Health & Safety is launching a New Laboratory Registration System that will help Principal Investigators, Lab Managers, EH&S Staff and Emergency Responders with:

  • Conducting Hazard Assessments;
  • Establishing administrative procedures, engineering controls, and personal protective equipment (PPE) requirements, to eliminate or minimize potential exposures;
  • Identifying training requirements and training history for all laboratory personnel;
  • Reporting of hazardous material inventories required by federal regulations;
  • Documenting and tracking inspections;
  • Providing critical hazard and contact information for emergency responders.

What do you need to do?

Principal Investigators and lab groups are asked to take the following actions by January 31, 2015.

  • Register your lab(s) in the new Laboratory Registration System (see link below).
  • Conduct an inventory of all infectious agents and toxins.
    • Properly dispose of all legacy cultures and samples.
    • Maintain a record of all infectious agents and update information in the Laboratory Registration System.
    • Mark all storage units/areas that have been inventoried with a Biosafety Stewardship Label
  • Reexamine current laboratory-specific risk assessments, policies, and procedures, and update them as necessary to optimize effectiveness.
  • Reinforce training of all laboratory personnel, including any new or refresher training.

To register your lab, please go to our Laboratory Registration System web page.

Environmental Health & Safety (EH&S) is continuing to work with the Institutional Biosafety Committee (IBC) and the University Laboratory Safety Council to review and update policies and procedures, training programs, website information and guidance documents. If you have any questions please email, or contact any EH&S Lab Safety Staff member below.

Human Salmonella Typhimurium Infections Linked to Exposure to Clinical and Teaching Microbiology Laboratories

what you work with can make you sickThere has been another significant outbreak of illnesses that is linked to college microbiology teaching labs. This is a strong reminder that we need to be vigilant to ensure that microorganisms that we work with at the lab bench STAY IN THE LABORATORY.

Following proper procedures, following good housekeeping guidelines, utilizing your personal protective equipment, and practicing good personal hygiene habits in the lab help to ensure that you don't bring these potentially hazardous microorganisms home with you (on your hands, clothes, office supplies) or worse, within you!

Post this flyer in your lab as a daily reminder!

Important Statistics!

  • A total of 41 persons infected with the same strains of Salmonella Typhimurium were reported from several states since November 1, 2013.
  • 62% of ill persons were ages 21 years of age or younger.
  • 36% of ill persons were hospitalized. No deaths were reported.
  • Epidemiologic and laboratory findings linked these Salmonella Typhimurium infections to exposure to various clinical and college and university teaching microbiology laboratories.
  • These strains of Salmonella Typhimurium have been associated with outbreaks linked to microbiology laboratory exposure in the past.
  • Microorganisms used in microbiology laboratories can make you or others who live in your household sick, especially young children, even if they have never visited the laboratory.

Tips on how to keep you and your loved ones safe!

  • Either non-pathogenic or attenuated bacterial strains should be used when possible, especially in teaching laboratories. This practice will help reduce the risk of students and/or their family members becoming ill.
  • Guidance documents for work with Salmonella and other similar human pathogens can be found on the Key Resources page.
  • Laboratories should consider posting the flyer in an area of the laboratory where students and employees can frequently view it.

Here is more information from the CDC on the outbreak:

Centers for Disease Control - June 5, 2014

CDC collaborated with public health officials in several states to investigate human Salmonella Typhimurium infections linked to exposure to various clinical and college and university teaching microbiology laboratories. Public health investigators used the PulseNet system to identify cases of illness that may be linked to microbiology laboratory exposure. PulseNet, the national subtyping network of public health and food regulatory agency laboratories coordinated by CDC, obtains DNA "fingerprints" of Salmonella bacteria through diagnostic testing with pulsed-field gel electrophoresis, or PFGE. These strains of Salmonella Typhimurium were indistinguishable by PFGE pattern from commercially available Salmonella Typhimurium strains used in laboratory settings for teaching or quality control purposes. These commercially available strains are known to be present in several teaching laboratories associated with ill persons.

A total of 41 persons infected with the same strains of Salmonella Typhimurium were reported from several states since November 1, 2013, including Illinois, Indiana, Kentucky, Maine, Massachusetts, Missouri, New Hampshire, New Jersey, Ohio, Pennsylvania, Virginia, Washington, and Wisconsin.

Among the persons who reported the date they became ill, illnesses began between November 1, 2013 and May 3, 2014. Ill persons ranged in age from younger than 1 year to 87 years, and the median age was 20 years. Sixty-two percent of ill persons were 21 years or younger. Seventy-six percent of ill persons were female. Among 28 ill persons with available information, 10 (36%) were hospitalized. No deaths were reported.

In interviews, ill persons answered questions about different exposures in the week before becoming ill. Eighteen (86%) of 21 ill persons interviewed reported being enrolled in either a human biology course or microbiology course. Fifteen (83%) of these 18 ill persons were students, and three (22%) were employees. Many ill persons reported several behaviors while they were working in the laboratory that would increase the risk of acquiring a Salmonella infection, including not wearing gloves or lab coats, lack of handwashing, and using the same writing utensils and notebooks outside of the laboratory. Additionally, many ill persons did not recall receiving laboratory safety training.

In 2011, a total of 109 illnesses with one of these same strains of Salmonella Typhimurium were linked to exposure to clinical and teaching microbiology laboratories. Findings of that investigation indicated that teaching and clinical microbiology laboratory instructors should enhance training of students and staff on biosafety measures necessary in the laboratory.
