[A study carried out in 1989 at the Sant'Antonio Hospital of Ovada on food poisoning in personnel handling and selling food products and drinks].

: The search for Salmonella spp in the faeces and of Staphylococcus aureus in pharyngeal pads during examinations for the renewal of the Medical Fitness Booklet, leads to a number of considerations of a technical-health and economic nature. Whereas the identification of Staphylococcus aureus is fairly straightforward, that of salmonella in the faeces is not so easy. Doubtful results are commonplace and bacteria are often found with features similar to salmonella; this means extra examinations with commitment of time, money etc.
