Results The incidence took on a point - source epidemic, and the minimum, maximum and median latent period were 5 minutes, 260 minutes and 25 minutes, respectively. The content of nitrite in suspected food ranged from 0.83 ×10^4 to 1. 13 × 10^4 mg/kg, and the amount of nitrite in two vomits was 94. 7 and 1.65 × 10^3 mg/kg.
