Maybe not. I suggest you check the relevant hygiene standards according to the specific food categories of your factory, because the general hygiene standards are described as follows:

4.2.3 The factory should be far away from harmful places. Buildings and peripheral roads or roads in the production area should have protective belts. The distance can be stipulated separately by the hygienic standard of each food factory according to the characteristics of each food factory.

In the catering industry and food business industry, there is this regulation, which is more than 25 meters away from the pollution source. The specific provisions are as follows:

Hygienic requirements for site selection

(a) shall not be located in areas susceptible to pollution, should choose dry terrain, water supply and drainage conditions and power supply area.

(2) It should be more than 25m away from pollution sources such as cesspits, sewage ponds, garbage dumps (stations) and dry toilets, and should be set outside the influence range of diffuse pollution sources such as dust, harmful gases and radioactive substances.
