We perform analyzes of the microbiological purity of packaging in the following directions:

  1. Total number of aerobic microorganisms
  2. Total yeast/mold count
  3. The presence of Escherichia coli
  4. Presence of Staphylococcus aureus
  5. The presence of Pseudomonas aeruginosa
  6. Presence of Salmonella
  7. presence of clostridium
  8. Presence of bile-tolerant gram-negative bacteria
  9. other markings indicated by the customer

Evaluation criteria and research methods

We perform analyzes of the microbiological purity of packaging according to:

  1. methodological procedure developed in the Mikrolab Laboratory based on Pharmacopoeial methods
  2. methodological procedure developed in the Mikrolab Laboratory based on ISO standards
  3. client methodologies


To packaging manufacturers for:

  1. cosmetics industry
  2. pharmaceutical industry
  3. food industry
  4. other industries


In the case of packaging, there are no standardized legal acts concerning research methods, therefore methodological procedures developed in the Mikrolab Laboratory are used in the microbiological purity tests. In accordance with the Good Manufacturing Practice (GMP) guidelines, packaging materials should be controlled and tested, as they may cause microbiological contamination of manufactured products.


Mikrolab has the permission of the Chief Pharmaceutical Inspector to manufacture (test) medicinal products and test medicinal products (for clinical trials) in the scope of microbiological quality control of non-sterile products.

Mikrolab has a GMP certificate approved by the Chief Pharmaceutical Inspector.

Mikrolab has a research laboratory accreditation certificate issued by the Polish Center for Accreditation, accreditation number AB 1531

Mikrolab has been approved by the State Sanitary Inspection for water testing. The results are honored by the Sanitary and Epidemiological Stations.

Why is it necessary to test the microbiological purity of packaging?

As a rule, in the case of packaging, the technological process guarantees the microbiological purity of the packaging. Particularly important is the assessment of packaging during storage and transport. The manufacturer or supplier must be aware that microbial secondary contamination may occur during this time. Packaging in direct contact with the product may affect the quality of the product and its durability. Packaging can contaminate the product, which can have a negative impact on the safety and health of consumers.

One of the most dangerous types of threats to food contact packaging is biohazards. Microbiological tests of individual packaging are carried out in order to determine the number of microorganisms present in them. The packaging does not have predetermined standards of microbiological quality. To assess the microbial contamination of the surface of packaging materials, both reference and alternative methods can be used.
