Fallstudie: Listerien Reduction on Food Contact Surfaces at a Poultry Processing Plant

Bereich der Besorgnis

Listeria monocytogenes was found on food and non-food contact surfaces in a large poultry further processing plant.

Ausgabe

A large poultry further processing plant was experiencing numerous Listeria monocytogenes positives on non-food contact surfaces and sporadic positives on food contact surfaces.

Hintergrund

The plant experienced a higher number of positive Listerien incidences during the summer. When a presumptive positive was found, a more intense cleaning regiment was required, extending the time needed for sanitation.

Empfehlungen

The plant began using Sterilex Ultra Disinfectant Cleaner Solution 1 (Solution 1) and Sterilex Ultra Aktivator Lösung (Solution 2), an EPA-registered two-part solution disinfectant on food contact surfaces weekly starting in January and saw an immediate reduction in the number of Listerien positives. Starting May through October, usage of the product was increased to twice per week to help control Listerien positives over the warmer summer months. The PerQuat® solution was applied to equipment surfaces during pre-op and then rinsed before going into production.

Ergebnisse

The plant saw an immediate reduction in Listerien compared to the previous year.

Surface Area	Year 1 Hits	Year 2 Hits	Reduction
Oberflächen, die nicht mit Lebensmitteln in Berührung kommen	47	0	100%
Oberflächen mit Lebensmittelkontakt	7	2	71.5%

Schlussfolgerung

This case study suggests that Sterilex Ultra Disinfectant Cleaner Solution 1 and Sterilex Ultra Activator Solution is effective at killing stubborn and hard to control pathogens, including Listerien on both food contact and non-food contact surfaces.

On equipment where Solution 1 and Solution 2 were applied, the plant saw a 70–100% decrease in Listerien positives. Effective maintenance procedures with Sterilex PerQuat technology is essential to reducing pathogen loads and removing Listerien and other pathogens.
