Summary
Essential oils show promise as safer alternatives to formaldehyde for sanitizing poultry hatching eggs, reducing microbial contamination. Further research is needed to confirm their safety and economic viability for the poultry industry.
Area of Science:
- Poultry Science
- Microbiology
- Toxicology
Background:
- Formaldehyde is widely used to sanitize hatching eggs, but poses toxic risks to humans and avian embryos.
- Increased poultry production necessitates effective and safe methods for managing hatching egg contamination.
Purpose of the Study:
- To review the antimicrobial efficiency, embryo toxicity, and production effects of essential oils as hatching egg sanitizers.
- To assess essential oils as potential substitutes for formaldehyde in poultry production.
Main Methods:
- Literature review of studies on essential oil antimicrobial activity.
- Assessment of essential oil toxicity in avian embryos and chicks.
- Evaluation of essential oils' impact on poultry production parameters.
Main Results:
- Most essential oils demonstrate antimicrobial properties and lower toxicity compared to formaldehyde.
- Essential oils present a potentially safer alternative for minimizing microbial exposure to hatching eggs and embryos.
Conclusions:
- Essential oils are promising substitutes for formaldehyde in hatching egg sanitation.
- Further studies are required on the microbiological impact on hatched chicks and the economic feasibility of essential oils.

Cleaning, disinfection, and sterilization are the methods that help to break the infection chain and prevent disease.
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Chemicals play important roles in controlling microbial growth by targeting microbial structures and functions as sanitizers, antiseptics, disinfectants, and sterilants.Alcohols are commonly used sanitizers, effectively disrupting lipid membranes, which compromises cell integrity. They are also used as antiseptics and disinfectants due to their rapid action and versatility.Phenols and their derivatives phenolics , known for denaturing proteins and disrupting cell membranes, are particularly...

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

In healthcare, the chemical method of sterilization uses chemical sterilants to treat surgical instruments and medical supplies to help prevent the transmission of infectious pathogens to patients. Due to heat sensitivity, most medical supplies and equipment should not be exposed to high temperatures. These parts include rubber, plastic, glass, and other similar elements.
