Middle school students can use preserved pigs to begin their exploration of human body systems and structure and function. How can I be sure you are in compliance with regulations? Current laboratory guidelines for working with infectious microorganisms at biosafety level (BSL) 3 recommend that all laboratory waste be decontaminated before disposal by an approved method, preferably within the laboratory.1013 These same guidelines recommend that all materials removed from a BSL 4 laboratory (unless they are biological materials that are to remain viable) are to be decontaminated before they leave the laboratory.1013 Recent federal regulations for laboratories that handle certain biological agents known as select agents (i.e., those that have the potential to pose a severe threat to public health and safety) require these agents (and those obtained from a clinical specimen intended for diagnostic, reference, or verification purposes) to be destroyed on-site before disposal.1412 Although recommendations for laboratory waste disposal from BSL 1 or 2 laboratories (e.g., most health-care clinical and diagnostic laboratories) allow for these materials to be decontaminated off-site before disposal, on-site decontamination by a known effective method is preferred to reduce the potential of exposure during the handling of infectious material.

Frogs Used for Dissection Come From If there is no damage to the acrylic container you may refill the museum mount yourself using 3% formalin solution. Nothing that happens in the labor other workplace is as important as your health and safety. The most practical approach to medical waste management is to identify wastes that represent a sufficient potential risk of causing infection during handling and disposal and for which some precautions likely are prudent.2 Health-care facility medical wastes targeted for handling and disposal precautions include microbiology laboratory waste (e.g., microbiologic cultures and stocks of microorganisms), pathology and anatomy waste, blood specimens from clinics and laboratories, blood products, and other body-fluid specimens.2 Moreover, the risk of either injury or infection from certain sharp items (e.g., needles and scalpel blades) contaminated with blood also must be considered. The US Fish and Wildlife Service and the US Department of Agriculture both monitor the trade in biological specimens. There are 3 main chemicals used as preservation fluids in the Dissecting Room: phenoxyethanol (2% in solution); methylated spirits (10%) & formalin (5%) Web11.

Yes, every preservation method yields specimens that are safe for your students to use, provided that standard lab safety practices (hand and eye protection) are used. The federal OSHA standard for formaldehyde exposure is 0.75 ppm over an 8 hour period. In an era when local, state, and federal health-care facilities and laboratories are developing bioterrorism response strategies and capabilities, the need to reinstate in-laboratory capacity to destroy cultures and stocks of microorganisms becomes a relevant issue.1423 Recent federal regulations require health-care facility laboratories to maintain the capability of destroying discarded cultures and stocks on-site if these laboratories isolate from a clinical specimen any microorganism or toxin identified as a select agent from a clinical specimen (Table 27).1412, 1413 As an alternative, isolated cultures of select agents can be transferred to a facility registered to accept these agents in accordance with federal regulations.1412 State medical waste regulations can, however, complicate or completely prevent this transfer if these cultures are determined to be medical waste, because most states regulate the inter-facility transfer of untreated medical wastes. This plain preserved squid specimen is typically genus Loligo. What about fetal pigs? Can you help? The infamous preservative smell?
