title: [Occupational exposure to biological agents intentionally used in Polish enterprises].
abstract: BACKGROUND
  The paper presents the intentional use of biological agents for industrial, diagnostic and research purposes in Polish enterprises.
  
  
  METHODS
  The National Register of Biological Agents (Krajowy Rejestr Czynników Biologicznych - KRCB) is an online database that collects the data on the intentional use of biological agents at work in Poland.
  
  
  RESULTS
  As of December 2013 there were 533 notifications in KRCB, mainly for diagnostic (73%), research (20%) and industrial purposes (7%). Mostly there were hospital diagnostic laboratories (37%), and other laboratories (35%), as well as higher education and research institutions (11%). In total, 4015 workers (91.7% of women, 8.3% of men) were exposed tobiological agents. Agents classified in risk group 2 were used in 518 enterprises, and in risk group 3 in 107 enterprises. Of those agents the following bacteria were the most frequently used: Escherichia coli except for non-pathogenic strains (455 enterprises and 3314 exposed workers); Staphylococcus aureus (445 and 3270); and Pseudomonas aeruginosa (406 and 2969, respectively). In 66 enterprises there were used biological agents recognized by the International Agency for Research on Cancer (IARC) as carcinogens. They are viruses: Epstein-Barr (7 enterprises, 181 exposed workers); hepatitis B (16 and 257); hepatitis C virus (15 and 243); human immunodefi- ciency virus (8 and 107); human papillomaviruses (2 and 4); parasites: Clonorchis viverrini (1 and 2 ); Clonorchos sinensis (1 and 2); Schistosoma haematobium (1 and 2) and bacteria Helicobacter pylori; (15 and 230, respectively).
  
  
  CONCLUSIONS
  The National Register of Biological Agents at Work permits to evaluate the situation of occupational exposure to biological agents used intentionally in enterprises in Poland.
