Use of disposable masks against Staphylococcus aureus in the chicken slaughter industry
ABSTRACT: The present study evaluated the effectiveness of using disposable masks in mitigating the spread of Staphylococcus aureus during the chicken cutting process in a large poultry abattoir. The identification of carriers of S. aureus and the influence of the time of use of disposable masks was...

| description | ABSTRACT: The present study evaluated the effectiveness of using disposable masks in mitigating the spread of Staphylococcus aureus during the chicken cutting process in a large poultry abattoir. The identification of carriers of S. aureus and the influence of the time of use of disposable masks was carried out. Contamination of utensils and equipment by S. aureus and products by mesophilic aerobes was determined, with and without the use of masks. The efficiency of different commercial masks was evaluated against S. aureus under simulated conditions. The results revealed that 36% of workers on processing lines at the abattoirs carried S. aureus. An increase in S. aureus counts was observed in masks worn by employees for up to 3 h. The transfer of microbial load to utensils was enhanced in the absence of the mask and over time. The breast fillets evaluated showed no difference in the count of mesophilic bacteria with and without the use of masks by employees, conversely, the cuts of thigh and drumstick, thigh fillet and drumstick and wings showed a significant difference with average counts lower than 2 .96 Log CFU/g. Tests under simulated conditions demonstrated the effectiveness of commercial masks in retaining microorganisms. The test mask used by the abattoirs proved to be inefficient, allowing the passage of sprays containing S. aureus, at 6, 15 and 25 cm, with 2.53, 1.74 and 0.66 Log CFU/plate, respectively. This mask saturated, creating a barrier effect that increased contamination in the employees’ work area. |
