设施、清洁与虫害第 312 / 320 题
A high-temp dish machine's data plate lists operating temperatures, but the manager wants to confirm dishes are actually being sanitized. What is a reliable check?
a.Assume it works because it is new
b.Feel the dishes with a bare hand
c.Use a maximum-registering thermometer or heat-sensitive test strip to confirm the dish surface reaches about 160°F
d.Only read the machine's built-in gauge and never verify
解析
To confirm a high-temperature machine is sanitizing, the manager should verify that the dish surface actually reaches about 160°F, using a maximum-registering thermometer or a heat-sensitive label run through the machine. The built-in gauge shows manifold temperature but can be inaccurate, so independent verification matters. Touching dishes by hand is neither safe nor a valid measurement.
