Recontamination via air should be a

Recontamination via air should be also considered if food products stand for a long time exposed to airborne contamination areas.

The number of microorganisms that enters the product via air depends on the settling velocity of the microorganisms, but also on the concentration of microorganisms in the air, and the exposure time and area of the product

Other studies made in processing plants or slaughters report that high air contamination levels are caused by aerosol formation, people in the area and junction of dirty and clean area

To our knowledge, no research has been developed in hospitals describing air contamination routes, thus the information generated in our study could be used to implement further management measures in other healthcare settings with the aim of reducing airborne contamination
