Research – Antibacterial action of slightly acidic electrolytic water against Cronobacter sakazakii and its application as a disinfectant on high-risk contact surfaces

Frontiers In.org

Powdered infant formula (PIF) is prone to Cronobacter sakazakii (C. sakazakii) contamination, which can result in infections that endanger the lives of newborns and infants. Slightly acidic electrolytic water (SAEW) has shown antibacterial effects on a variety of foodborne pathogens and has a wide applicability in the food industry. Here, the antibacterial activity of SAEW against C. sakazakii and its use as a disinfectant on contact surfaces with high infection transmission risk were investigated. The inactivation of SAEW on C. sakazakii was positively correlated to the SAEW concentration and treatment time. The antibacterial effect of SAEW was achieved by decreasing the intracellular adenosine triphosphate (ATP), K+, protein, and DNA contents of C. sakazakii, reducing the intracellular pH (pHin) and destroying the cell morphology, which led to inactivation of C. sakazakii ultimately. To test the applicability of this study, the results showed that approximately 103 CFU/cm2 of C. sakazakii were successfully inactivated on stainless steel and rubber surfaces after a 30 mg/L SAEW treatment for 20 s. These results indicate the antibacterial mechanism and potential application of SAEW against C. sakazakii, as well as a new strategy for the prevention and control of C. sakazakii on stainless steel and rubber surfaces.

Research – Cronobacter sakazakii

ACSA

Cronobacter sakazakii  is a   gram-negative, motile, non-spore-forming, facultative anaerobic, bacillary-shaped, oxidase-negative, catalase-positive bacterium Due to its ability to form biofilms and its resistance to desiccation, it can be found widely in soil, water, plants and animals, being able to grow in a wide range of temperatures (6°C-47°C).

Cronobacter sakazakii  infection  is uncommon worldwide, but presents a high proportion of cases with neurological complications and death. The infection causes diarrheal enteritis, which often turns bloody and, in some cases, can be complicated by meningitis that leaves neurological sequelae or ends in the death of the infected baby.

The organism has been isolated from various foods of vegetable or animal origin, both dehydrated, smoked, frozen, etc. C. sakazakii  is an occasional contaminant of different foods such as cereals, porridges, dehydrated for special diets, foods for medical uses, and powdered infant formulas, being able to persist in these foods for at least 2 years due to their ability to withstand environments dry It is also necessary to consider powder preparations intended for elderly people and those intended for special medical uses given the special vulnerability of this population group.

Powder formulas

Powdered formulas are not sterile and, although they are heat treated during manufacture and conform to established microbiological criteria, they may occasionally contain low concentrations of microorganisms, including pathogens such as Cronobacter sakazakii and Salmonella enterica.

During manufacturing, microorganisms can be introduced into the powder preparations through the ingredients added in the dry mixing operations or from the environment during the drying or packaging stage. Also, powdered formulas can be contaminated by improper preparation at home.

These microorganisms are not able to multiply in dry powder preparations, but they can survive there for long periods of time, even longer than a year. Instead, the reconstituted preparation offers an ideal environment for them to proliferate.

The large-scale production and distribution of these products and the low number of infections in nursing infants indicate that the products are generally safe.

Research -EFSA – Persistence of microbiological hazards in food and feed production and processing environments

EFSA

Listeria monocytogenes (in the meat, fish and seafood, dairy and fruit and vegetable sectors), Salmonella enterica (in the feed, meat, egg and low moisture food sectors) and Cronobacter sakazakii (in the low moisture food sector) were identified as the bacterial food safety hazards most relevant to public health that are associated with persistence in the food and feed processing environment (FFPE). There is a wide range of subtypes of these hazards involved in persistence in the FFPE. While some specific subtypes are more commonly reported as persistent, it is currently not possible to identify universal markers (i.e. genetic determinants) for this trait. Common risk factors for persistence in the FFPE are inadequate zoning and hygiene barriers; lack of hygienic design of equipment and machines; and inadequate cleaning and disinfection. A well‐designed environmental sampling and testing programme is the most effective strategy to identify contamination sources and detect potentially persistent hazards. The establishment of hygienic barriers and measures within the food safety management system, during implementation of hazard analysis and critical control points, is key to prevent and/or control bacterial persistence in the FFPE. Once persistence is suspected in a plant, a ‘seek‐and‐destroy’ approach is frequently recommended, including intensified monitoring, the introduction of control measures and the continuation of the intensified monitoring. Successful actions triggered by persistence of L. monocytogenes are described, as well as interventions with direct bactericidal activity. These interventions could be efficient if properly validated, correctly applied and verified under industrial conditions. Perspectives are provided for performing a risk assessment for relevant combinations of hazard and food sector to assess the relative public health risk that can be associated with persistence, based on bottom‐up and top‐down approaches. Knowledge gaps related to bacterial food safety hazards associated with persistence in the FFPE and priorities for future research are provided.

Abstract

Listeria monocytogenes (in the meat, fish and seafood, dairy and fruit and vegetable sectors), Salmonella enterica (in the feed, meat, egg and low moisture food sectors) and Cronobacter sakazakii (in the low moisture food sector) were identified as the bacterial food safety hazards most relevant to public health that are associated with persistence in the food and feed processing environment (FFPE). There is a wide range of subtypes of these hazards involved in persistence in the FFPE.
