How do we identify objectionable microorganisms?
In order to determine if an organism is objectionable, the manufacturer must consider the risk imposed by the organism. Factors to take into consideration are the microorganism’s characteristics, the route of administration of the drug, the nature of the product, and the intended recipient.
Is Bacillus cereus an objectionable organism?
The organisms Burkholderia cepacia and Bacillus cereus are not objectionable in all non-sterile medications by the above definition. However, given recent events a finding of either organism in any non-sterile medication will most likely elicit interest from a regulatory agency.

Is Bacillus subtilis an objectionable organism?
subtilis, if they survive the manufacturing process, and are found in numbers less than 100 cfu/mL in the product would not be objectionable. The reduced water activity, low pH, and robust preservative system will prevent the growth of spore-forming bacteria in the oral solution.
What are objectionable microorganisms?
An objectionable microorganism can be defined as a microorganism that can cause illness in the patient or that can adversely affect a nonsterile product. 2. This includes the potential to degrade a product’s stability.
What is Bile tolerant Gram negative bacteria?
Bile-tolerant gram-negative bacteria can survive in the human stomach (bile-tolerant) and they have a protective cell wall that causes them to turn red when subjected to the gram staining process (gram-negative). This combination of characteristics makes BTGN bacteria potentially harmful to humans.
What is Bile tolerant Gram-negative bacteria?
How would you decide if a microbial contaminant found in your formulation is an objectionable organism?
