Medical Surveillance 
Because of our long-standing interest and responsibility for the 
health and well-being of our employees, we have for a number of years 
carried out programs of medical surveillance of workers in both laboratory 
and production areas. The surveillance program has been altered slightly 
for workers in recombinant laboratories. Our program includes the 
following procedures: 
1. Medical questionnaire and standard periodic physical examination 
including complete blood count, urinalysis, multicomponent blood 
chemical analysis (SMA 12), and posterior-anterior chest x-rays 
on an annual basis. 
2. Baseline frozen serum samples are obtained and maintained on all 
employees working with recombinant DNA for future comparative 
analysis, if deemed necessary. 
3. All breaches in containment are recorded and reported immediately 
to the Biological Safety Officer and a physician in industrial 
medicine for appropriate action which may include monitoring for 
the development bf any illness. 
4. All illnesses must be reported to supervisors. 
5. Any employees who are off work for illness for more than five 
days must report to a physician in industrial medicine before 
being allowed to return to work. 
6. Any employee taking antibiotics is restricted from an area of 
recombinant DNA research until five days after the discontinuance 
of the antibiotics. 
7. A computer listing of all workers involved in recombinant DNA 
activities is maintained and updated as required.
