Impact of Improved Sanitation Standard Operating Procedures on Microbial Populations at Three Tree Fruit Packing Facilities.

Cleaning and sanitizing are of vital importance to control Listeria monocytogenes in food processing facilities. Here, we evaluated the effect of four cleaning and sanitation standard operating procedures (SSOPs; T1, T2, T3, T4) on the reduction of total aerobic mesophilic microorganisms, the occurrence of L. monocytogenes, and the microbiota composition in three tree fruit packing facilities (F1, F2, and F3) over two packing seasons (Y1 and Y2).

Genomic analysis of a cAmpC (CMY-41)-producing Citrobacter freundii ST64 isolated from patient.

Antibiotic resistance in Citrobacter freundii is a public health concern. This study evaluated the closed genome of a C. freundii isolated from the stool of a hospitalized patient initially related to a Salmonella outbreak.

Longitudinal Survey of Aeromonas hydrophila and Foodborne Pathogens in a Commercial Aquaponics System.

Aquaponic production of fresh produce is a sustainable agricultural method becoming widely adopted, though few studies have investigated potential food safety hazards within commercial systems. A longitudinal study was conducted to isolate and quantify several foodborne pathogens from a commercial, aquaponic farm, and to elucidate their distribution throughout. The survey was conducted over 2 years on a controlled-environment farm containing Nile tilapia (Oreochromis niloticus) and lettuce (Lactuca sativa).

Effect of aquaponic water and substratum material on biofilm formation by Aeromonas hydrophila.

Aeromonas hydrophila is a zoonotic pathogen causing illness in fish and susceptible humans. This emerging pathogen has been isolated within aquaponic systems and could cause disease in fish and a hazard to humans consuming aquaponic produce. This study determined whether A.

The composition of environmental microbiota in three tree fruit packing facilities changed over seasons and contained taxa indicative of L. monocytogenes contamination.

Background: Listeria monocytogenes can survive in cold and wet environments, such as tree fruit packing facilities and it has been implicated in outbreaks and recalls of tree fruit products. However, little is known about microbiota that co-occurs with L. monocytogenes and its stability over seasons in tree fruit packing environments.
