To describe and analyse from a clinical and epidemiological point of view, a food borne outbreak in a psychiatric institution in Granada, in 2015, and to examine whether treatment with psychoactive drugs constitutes a risk factor for the development of a food borne disease, analysing the degree of susceptibility according to the therapeutic group consumed. Ambispective cohort study. Residents were the unit of analysis. Our group carried out an active case search and a food survey. A search for other risks was developed as well as a food inspection. Location, time and individual variables were studied. A descriptive analysis was conducted (absolute and relative frequencies). Calculation of attack rates by building and by menu was made. Bi-variant analysis (Chi-square test, t-Student test) and relative risk were used as a measure of strength of association. For risk analysis of medication, a multivariate analysis using logistic regression was carried out. 18 cases with diarrhoea without fever were found (incubation period from 6 to 16hours). Cases were mild and self-limiting. The clinical manifestations, the temporal grouping of cases and the characteristics of the ingested foods, focussed suspicion on a bacterial toxin. Being equal in the rest of variables, the N03AF, and N03AG therapeutic groups confer greater risk of disease (odds ratio [OR]: 8.626; 95% confidence interval [95%CI]: 2.050-36.308; p=0.003; and OR: 14.516; 95%CI: 3.155-66.784; p=0.001, respectively). Decreased intestinal transit, caused by the administration of anticonvulsants, may increase exposure time of the intestinal mucosa to the toxin, increasing the risk of disease and suffering from complications. An additional hygienic effort should be made in this type of institution to prevent these pathologies.
