The management of the issue of medical and pharmaceutical waste is embarrassing to many countries. Morocco does not escape this reality. Since the first circular in 1991, Morocco has developed the legal arsenal because they pose risks to health and environment.
The objective of our study is to characterize the risk of bacteriological solid waste of care units in Mohamed V hospital.
The sample includes five Care units with significant waste production: intensive, the burnt, the Emergent, the Respiratory and central operating room. This hospital is a regional focus with a bed capacity of 388 and serves a population of 2 186 000 citizen. Twice, it won the first prize of quality competition organized annually by the Ministry of Health.
We advocated as methodology the analysis samples in medical laboratory. The samples are as follows: Ten samples from the Medical waste before treatment at ECODAS T300 grinder and five after theme treatment.
Pathogens were obvious from the analysis before the treatment, which is normal. However, an alarming point is their persistence even after treatment with the grinder.
These results raise the question of the effectiveness of treatment systems by grinding in general and in particular for ECODAS T300: which it is designed for sterilization (complete destruction of germs) or simply for disinfecting (reduction of microbial burden)?

The care-associated infections (CAI) are a public health problem. WHO showed that 8.7 % of hospital were affected by CAI. In Morocco in 1994, the prevalence of CAI was 10% in regional hospitals. The surgical site infections (SSI) are the most common complication of surgery. This is due to several factors related to the person, staff, the environment and the organization of care. The study aims to determine the prevalence and factors of Surgical Site Infections at the Regional Hospital of Meknes. This is a descriptive cross-sectional study conducted by a team previously formed using a plug which is filled in front of 111 patients ; and a questionnaire administered to 20 nurses of surgery service. The prevalence of SSI is 16 %. Diabetics are exposed to five times more likely to develop an SSI. Age is not a risk factor even the slice of more than 50 years accounted for 33 % of SSI cases. Over three years, less than 50 % of staff trained in hospital hygiene.
