3. Hazards Identification

Emergency Overview: : The microorganisms used in this product are BioSafety Class 1 microorganisms, as defined by the Centers for Disease Control as unlikely to cause disease in healthy humans or animals. However, persons with compromised immune systems should avoid contact with open wounds and/or breathing dust or mist from manufacturing processes. These organisms are susceptible to many commonly used antibiotics, and Alken-Murray is willing to supply antibiotic sensitivity information to any doctor or import health authority requesting it. Although bacterial cultures included in this product were grown in a sterile aqueous medium containing a variety of nutrients, including corn syrup solids, digests of soybean and/or skim milk, glucose or other sugars, vegetable oils, including olive oil, yeast extract, mineral salts, etc., the concentrations of these residual nutrients are believed to be below levels capable of triggering irritation

Access the antibiotic sensitivity chart at , which provides results of Kirby-Bauer antibiotic sensitivity screening of Alken-Murray's commercial culture strains, on a strain by strain basis. See more about Alken-Murray's QC policies in that document.

Potential Health Effects:

  • Signs and Symptoms of Acute Overexposure: Eye, skin irritation
  • Signs and Symptoms of Chronic overexposure: Dermatitis and skin sensitization
  • Medical Conditions Generally Aggravated by Exposure: Allergies, dermatitis.
  • Ingestion: No effect if ingested in small amounts. Relative to other materials, a single dose of this product is rarely toxic by ingestion. Irritation of the mouth, pharynx, esophagus and stomach can develop following ingestion.

4. First Aid Measures

  • Inhalation: Remove victim to fresh air
  • Ingestion: Give victim water or milk to drink to dilute the product. Get medical advice..
  • Skin Contact: Remove contaminated clothing and footwear. Wash skin with soap and water. Wash clothing before reuse.
  • Eye Contact: Immediately flush eyes with water for 15 minutes. Get medical attention.
  • Note to Physician: If patient's immune system is compromised, request antibiotic sensitivity chart from Alken-Murray Corporation by e-mail:

13. Disposal Considerations

 RCRA Hazard Class (if discarded): Neat, unused product is not considered a hazardous waste, according to RCRA regulations 40 CFR 261. For proper disposal of used materials, an assessment must be completed to determine the proper waste management options permissible under applicable rules, regulations and/or laws governing client's location.
