Microbiological Quality of Selected Local and Imported Non-Sterile Pharmaceutical Products in Dar es Salaam, Tanzania.

We recommend that pharmaceutical manufacturers abide by good manufacturing, distribution and storage practices to limit contamination and cross-contamination of products. Responsible drug regulatory authorities should heighten the frequency of inspection of manufacturing facilities and regularly conduct post-marketing surveillance (PMS) of registered products to assess continued conformity to GMP guidelines. Future studies should involve samples collected directly from manufacturing sites.
