“…The low energy electron beam is a rather innovative approach that was tested in a prototype machine. To the authors' knowledge, one publication has described the use of a similar technique to disinfect eggs until now [57]. Currently, no high throughput device for hatching egg disinfection is available.…”

The presence of extended-spectrum beta-lactamase (ESBL) producing Escherichia coli on poultry products is an important issue for veterinary and human health due to the zoonotic infection risk for producers and consumers. The present study focuses on testing the efficacy of six different disinfection methods on eggshell samples, aiming to reduce ESBL producing E. coli contamination on the hatching egg. Sterile eggshell cutouts were artificially contaminated with 10 8 cfu/ml CTX-M-1 producing E. coli and used as a carrier model to analyze the efficacy of six disinfection methods. The contaminated samples were separated into two groups; 1) contaminated and disinfected, 2) contaminated and non-disinfected. Six independent disinfection protocols were performed following product specifications and protocols. Each eggshell sample was separately crushed, and the total viable bacterial count was calculated to determine the disinfection efficacy. Five out of six tested methods (formaldehyde gassing, hydrogen peroxide + alcohol spray, essential oils spray, peracetic acid foam, and low energetic electron radiation) demonstrated a reduction or completely eliminated the initial ESBL producing E. coli contamination. One method (essential oils as cold fog) only partly reached the expected efficacy threshold (reduction of >10 2 cfu/ml) and the result differed significantly when compared to the reference method i.e. formaldehyde gassing.

“…To assess the disinfection capacity of this method, further studies must be performed to see how the adaptation of this prototype to a large scale will affect the disinfection capacity. Nevertheless, the results presented during this trial, as well as the lack of negative side effect post hatching [ 26 , 53 ], suggest that this method has potential as an alternative to formaldehyde once the appropriate field infrastructure is available.…”

“…Previous studies have already compared the disinfection efficacy as well as the adverse effects of various disinfection methods (formaldehyde, hydrogen peroxide + alcohol, peracetic acid and low energy electron beam) under in-vitro conditions [ 22 – 26 ] demonstrating the effectiveness of the disinfectants against various types of bacteria but they have never been compared on a large scale or under field conditions. By performing parallel field trials, we considered the practicability of the methods, providing us a better idea of the true performance and suitability of each disinfection method for the industry.…”

The disinfection of commercial hatching eggs before incubation is a common strategy to reduce potential vertical transmission of bacterial and fungal infections from the eggshell to one-day-old chicks that may prevail in poultry products and eventually reach the end consumer. The present investigation focuses on the parallel testing and application of four different disinfection methods (conventional and alternative) under commercial hatchery conditions against natural eggshell bacterial contamination. Hatching eggs from two ROSS 308 broiler breeder flocks were selected and divided into six different groups: two groups were not disinfected and served as negative controls, and four were independently disinfected following product specifications and protocols. From each group, a sample of 100 hatching eggs was selected for bacterial re-isolation, utilizing a modified shell rinse method. Colony-forming units (cfu) from the shell rinse suspensions were determined and analyzed to establish cfu values for each tested egg. These values were analyzed to determine the bacterial disinfection capacity of the four disinfection methods under commercial hatchery conditions. The tested methods were hydrogen peroxide + alcohol, peracetic acid, low energy electron beam, and the gold standard in practice: formaldehyde. Among these methods, formaldehyde, peracetic acid, and low energy electron beam showed a significant difference when compared to the non-disinfected groups whereas hydrogen peroxide + alcohol did not. The bacterial disinfection capacity of the tested methods was compared as well to the gold standard method formaldehyde fumigation and only low energy electron beam achieved similar disinfection levels as formaldehyde. According to our data, three methods significantly reduce the bacterial load on the eggshell of hatching eggs under commercial hatching conditions, including potential alternative methods such as low energy electron beam that perform similar to the gold standard in practice.

“…Regarding the control of the eggshell microbial load, Virkon S performed very well, as demonstrated in all studies, and had no record of significant loss in hatchability. Other examples that may be viable for hatching eggs are ammonium compounds [ 64 ], peracetic acid [ 75 ], nanosecond electron beam [ 66 ], low-energy electron irradiation [ 38 ] and ultraviolet radiation [ 83 ].…”

The sanitization of hatching eggs is the backbone of the hygienic–sanitary management of eggs on farms and extends to the hatchery. Poultry production gains depend on the benefits of sanitizers. Obtaining the maximum yield from incubation free of toxic sanitizers is a trend in poultry farming, closely following the concerns imposed through scientific research. The toxic characteristics of formaldehyde, the primary sanitizer for hatching eggs, are disappointing, but it is a cheap, practical and widely used antimicrobial. To overcome this shortcoming, multiple synthetic and natural chemical sanitizers have been, and continue to be, tested on hatching eggs. This review aims to evaluate the effects of different sanitizers on the microbiological quality of hatching eggshells and poultry health during embryogenesis and early stages after hatching.
