摘　　要：Market garden products can carry several types of microorganisms, and their consumption is the source of many cases of food poisoning. This work aimed to improve food safety in Benin. In characterizing strains of K. pneumoniae and fluorescent Pseudomonas spp. at the biochemical and molecular level, the target was to identify contaminated watering water and garden products sold during Cotonou in both the dry and rainy seasons. A total of 164 samples of market garden products and 22 samples of watering water were investigated. The results showed that 5.91% of market garden products and watering water were contaminated by K. pneumoniae and 20.43% by fluorescent Pseudomonas spp. During the dry season, cabbage was most contaminated by fluorescent Pseudomonas spp. (50%). Pool water was more contaminated with K. pneumoniae (17%). All isolated strains were resistant to both amoxicillin and penicillin. All strains of K. pneumoniae and fluorescent Pseudomonas spp. were not resistant to imipenem, and 22% of them produced penicillinase. Among the 49 strains producing penicillinase isolated, 64.29% and 21.43% carried bla_TEM and bla_SHV respectively while 14.28% carried bla_CTX-M genes. In light of the previously-developed results and considering the importance of horticultural products in Beninese food habits, we must improve national awareness of the risk for foodborne illness.Market garden products can carry several types of microorganisms, and their consumption is the source of many cases of food poisoning.
