The epidemiology of Salmonella involves food, especially meat and dairy products. These have a high salmonella outbreak in the summer. The majority of Salmonella enteritis in young children occurs in the form of scattered cases. At least 25% of summer gastroenteritis in young children is caused by Salmonella. In Western Europe, S. typhimurium accounts for nearly 70% of isolates. The objective of this study was to investigate the Salmonella contaminating meat and dairy products as well as define the percentages of contamination by Salmonella from 2004 to 2006, by the Department of Hygiene of Tunis. For this study, we collected samples in various motherboard solutions, and conducted a pre-nonselective enrichment in selective enrichment in isolation and identification and ultimately biochemical confirmation. One hundred and sixty two samples, 125 samples of meat products including 68 samples of red meat （beef and sheep, beef, offal and Merguez） and 57 samples of poultry （chicken and turkey）, 37 samples of milk products which included 32 samples of cheese and five samples milk, were analysed microbiologically from 2004 to 2006, in the Health Service in Tunis. These analyses include the detection and enumeration of Salmonella. From 2004 to 2006, the rate of infections by the Salmonella, meat and dairy products were： 55.9% for red meat, 71.9% for poultry, 68.8% for cheeses, 40% for milk. The meat of poultry is contaminated with Salmonella that the cheeses, which are more than red meats, which are also more contaminated than milk. This might be due to a lack of hygiene throughout the circuit processing （slaughter, transport, processing, etc.）. The increased risk of contamination of milk products by Salmonella is proportional to the manipulation done on these products. The latter must be handled by pasteurization and sterilization.
