Product Name: Propionibacterium acidipropionici
Other Names: Propionibacterium, P. acidipropionici, Bacterium involved in cheese fermentation
Recommended Use: Dairy fermentation, probiotic supplement, biotechnological applications
Supplier: Biotech laboratory or culture collection facility
Emergency Contact: Company’s emergency phone
Classification: Microbial culture, non-pathogenic under normal conditions
Label Elements: No signal word, symbol, or hazard statement as per standard GHS for non-pathogenic bacteria
Potential Health Effects: Possible irritation for sensitive individuals, especially immunocompromised
Routes of Exposure: Inhalation of dust, ingestion, direct eye or skin contact
Environmental Impact: Low risk to environment; natural soil microorganism
Cultural Form: Freeze-dried or liquid suspension of cells
Concentration: Typically 1×109 CFU/g in commercial products
Main Components: Live cells of Propionibacterium acidipropionici, residual cultivation media (may contain nutrients and trace salts)
Impurities: Trace components from growth medium may be present
Inhalation: Move exposed individual to fresh air, seek medical attention if respiratory irritation occurs
Skin Contact: Wash area thoroughly with soap and water
Eye Contact: Rinse eyes with clean water for several minutes; consult physician if irritation develops
Ingestion: Rinse mouth, drink water if feeling discomfort; seek attention for severe reactions or large ingestions
Suitable Extinguishing Media: Water spray, dry chemical, foam, or carbon dioxide
Special Hazards: Organic dust may promote minor fire risk if accumulated in large quantities
Protective Equipment: Standard firefighting attire, self-contained breathing apparatus for sustained fires
Hazardous Combustion Products: Typical for organic materials—may produce CO2 and CO
Personal Protection: Gloves and lab coat recommended, avoid breathing dust
Cleanup Procedures: Collect spills carefully by damp wiping or vacuuming with filter
Containment: Prevent dispersal into air or water systems
Environmental Precautions: Avoid release into municipal wastewater in high concentrations, though considered non-hazardous to environment
Safe Handling: Limit dust generation, minimize aerosol formation, use approved biosafety protocols in laboratory settings
Storage Conditions: Store at recommended low temperatures (often 2-8°C refrigerated, or -20°C if long-term), keep tightly sealed
Incompatibilities: Keep away from strong oxidizing agents, acids, and bases
Hygiene Measures: Wash hands after handling, do not eat or drink near storage or use areas
Control Parameters: No established occupational exposure limits
Engineering Controls: Biological safety cabinet for laboratory use or fermentation facilities with adequate ventilation
Personal Protective Equipment: Gloves, lab coat, protective eyewear when handling bulk cultures, mask or respirator to avoid inhalation of powders
Hygiene Practices: Remove contaminated clothing, wash hands after handling
Appearance: Off-white or beige powder, or opaque liquid suspension
Odor: Slightly musty or cheeselike, characteristic of propionic acid producers
pH (10% Solution): Typically around 6.0-7.0
Boiling Point: Not applicable (biological material)
Melting Point: Not applicable
Solubility in Water: Disperses or suspends; not truly soluble

Acute Toxicity: No known acute toxicity in healthy adults
Chronic Effects: No evidence of chronic health effects from occupational or incidental contact
Skin/Eye Sensitization: Rare sensitivity possible
Carcinogenicity: Not classified as carcinogenic by IARC, NTP, or OSHA
Mutagenicity: No evidence from existing literature
Medical Conditions Aggravated: Immunocompromised status may elevate risks
Ecotoxicity: Minimal impact, non-pathogenic, considered safe for use in food and feed processes
Mobility in Soil: As a soil microbe, it integrates into native populations
Persistence and Degradability: Cells do not persist in hostile environments; die-off occurs rapidly outside controlled conditions
Bioaccumulation Potential: No evidence for bioaccumulation
Aquatic Toxicity: Not harmful to aquatic organisms in normal commercial quantities
Waste Treatment Methods: Autoclave spent cultures and contaminated materials before disposal
Containers: Triple rinse and puncture before discarding
