Among the results it was obtained that the highest food attack rate (100%) was for polio sandwich, 100% global attack house, 64% clinical attack rate, co-culture confirmed case attack rate of 100 %, detention rate of 66%. The pathogen that was isolated corresponded to Salmonella sp Poly AI-N Group D1, in 100% of the faecal samples. Greater confirmation (phage topaz) showed the presence of Salmonella Group D1, factors I, 9 and 12 in 100%. It was concluded that the outbreak was due to Salmonella enteritidis 9.12 gmfagotype 1; The results suggest a common source outbreak.
