- 01HMV1B86X4VJRX8Y81XCWS0TK abstract "Although it is assumed that there is a risk of airborne contamination, during the filling of (semi) - liquid products, establishing guidelines for the microbial quality of air is challenging due to variations in air sampling techniques, a lack of consistent quantitative data and an abundance of speculation regarding the direct impact of air quality on the product contamination. This study aims to gather quantitative microbial and physicochemical (e.g. temperature, relative humidtity, …) data regarding air quality in companies packaging (semi) - liquid products towards guidelines that can justify investment costs for prevention, or prevent unexpected spoilage of products. Air quality is assessed in fourteen diverse (semi) - liquid food processing plants in Flanders, Belgium. Microbiological air samples were collected from each plant, both indoors and outdoors, on four separate days from January to September 2022. For each sample, possible influencing factors of airborne contamination, such as the type of ventilation system, personnel and their clothing, total particle count, relative humidity, temperature, processing and cleaning operations, and moving or rotating equipment during filling were considered. The study revealed wide-ranging air contaminants with indoor mesophilic bacteria (1.35 ± 0.65 log10CFU.m-3 and 3.42 ± 0.16 log10CFU.m-3), moulds/yeasts (1.22 ± 0.65 log10CFU.m-3 and 3.10 ± 0.08 log10CFU.m-3) among companies, regardless of their product type, location, personnel, particle count, temperature, and humidity. Companies with high-efficiency filter-equipped ventilation systems had lower concentrations of airborne microorganisms compared to those without ventilation systems; however, there was no correlation between particle counts and airborne microorganism levels. Active and passive measurements exhibited a strong correlation. Apart from the ventilation system, other considered influencing factors cannot be individually correlated with the amount of airborne microorganisms in the filling area of (semi) – liquid food products. Additionally, the total number of particles in the air cannot be used as a basis for establishing guidelines, as there is no correlation between particle count and the presence of microorganisms. The air quality in a food company is influenced by a combination of multiple factors, and it is the cumulative impact of these factors that determines the risk of airborne contamination.".
