I. Introduction
Meat processing is an important part of the food industry, but meat products are susceptible to microbial contamination and the processing process is complex, so the hygiene requirements are extremely high. As a key station facility to ensure the hygiene and safety of the meat processing environment, the personnel sanitation cleaning hygiene station plays an important and fundamental role in the entire production process.
II. Hygiene Challenges in the Meat Processing Industry
(I) Risk of Microbial Contamination
Meat itself is rich in nutrients such as protein and water, which is an ideal environment for the growth of microorganisms. From livestock slaughter to processing and packaging, each link may be contaminated by microorganisms such as bacteria, viruses, and parasites. For example, once common pathogenic bacteria such as Escherichia coli and Salmonella contaminate meat products, if consumers eat them, they may cause serious food poisoning incidents, posing a great threat to public health.
(II) Cross-contamination Hazards
There is a possibility of cross-contamination between multiple pollution sources and contaminated objects in meat processing plants. On the one hand, employees move between different processing areas. If effective cleaning and sanitizing are not carried out, they may bring contaminants from one area to another. For example, microorganisms contaminated in the area where raw meat is processed may be brought to the cooked meat processing area, causing cross-contamination. On the other hand, processing equipment, tools, work clothes, etc. may also become media for cross-contamination. If they are not cleaned and disinfected in time, they will cause the spread of microorganisms throughout the processing environment.
III. Components and functional characteristics of personnel hygiene cleaning stations
(I) Hand washing facilities stations
Induction faucets
- The use of induction faucets can prevent employees from manually touching the faucets and reduce the chance of re-contamination of their hands. It can provide water flow with suitable temperature and flow to ensure that employees can fully wash their hands.
Antibacterial hand cleaner
- Equipped with a special antibacterial hand cleaner, this type of hand cleaner can not only effectively remove hand dirt, but also kill common pathogenic microorganisms. For example, hand cleaners containing antibacterial ingredients such as triclosan can destroy the cell wall or cell membrane of microorganisms during hand washing and inhibit their growth and reproduction.
(II) Disinfection equipment
Hand sanitizer
- Use a spray of hand sanitizer. The disinfectant can spray the disinfectant evenly on the surface of the hands. Commonly used disinfectants such as alkyl dimethyl ammonium chloride + ethanol and compound disinfectants are widely used in food factories. They can be directly poured into the disinfection machine or container for use, which can quickly kill the microorganisms remaining on the hands.
-
Shoe cleaning and disinfection channel
- Employees need to pass through the shoe cleaning brush channel and shoe disinfection pool of the hygiene station to enter the processing workshop. Firstly, for the boot cleaning brush channel, brushes, and cleaning detergents are configured. When employees walk through, the soles will be evenly scrubbed. Secondly, for the boot disinfection pool, the chemicals disinfectant in the disinfection pool of the hygiene station are automatically proportioned. When employees step into the disinfection pool, their boots will be disinfected. The above two parts prevent pollutants such as soil and microorganisms carried by the soles of shoes from entering the workshop. For example, using chlorine-containing disinfectants to disinfect the soles can effectively inactivate a variety of bacteria and viruses.
-
(III) Changing room area
Work clothes storage cabinet
- Provide employees with special work clothes storage cabinets so that employees can store personal clothes separately from work clothes. Work clothes should be made of easy-to-clean, antibacterial materials, and should be cleaned and disinfected regularly to reduce the attachment and growth of microorganisms on work clothes.
Changing room ventilation system
- A good changing room ventilation system can maintain indoor air circulation, reduce humidity, and prevent mold and other microorganisms from growing and multiplying in the changing room environment. At the same time, the ventilation system can also remove odors in time to provide employees with a comfortable dressing environment.
IV. The important role of personnel hygiene cleaning stations in meat processing plants
(I) Preventing microbial contamination
Through the standardized use of personnel hygiene cleaning stations, employees can thoroughly clean their hands, and disinfect soles before entering the processing workshop, remove microorganisms carried on the surface of the body, and effectively reduce the number of microorganisms entering the processing environment. For example, studies have shown that employees who have undergone strict hand washing and disinfection procedures can reduce the number of microorganisms on their hands by more than 90%, greatly reducing the risk of microbial contamination of meat products.
(II) Reduce cross-contamination
The establishment of personnel hygiene cleaning stations helps break the transmission chain of cross-contamination. When employees switch between different processing areas, they wash their hands, disinfect, and perform other hygienic operations again to prevent contaminants from being brought from one area to another. At the same time, the cleaning and disinfection of work clothes and soles by the cleaning station also prevents these items from becoming the source of cross-contamination, ensuring the sanitation and safety of the entire processing process.
(III) Ensuring employee health
The working environment of meat processing plants has many health hazards. If employees are exposed to an environment with serious microbial contamination for a long time, their own health is easily threatened. Personnel hygiene cleaning stations reduce the risk of employees contracting diseases by providing good hygienic cleaning conditions and reducing the chances of employees coming into contact with pathogenic microorganisms. For example, it can effectively prevent employees from being infected with zoonotic bacteria, ensure the health of employees, and improve their work efficiency and work enthusiasm.
(IV) Comply with regulatory standards
With the increasingly stringent food safety supervision today, meat processing plants must comply with relevant regulatory standards. The construction and standardized use of personnel hygiene cleaning stations are among the important aspects of meeting these regulatory standards. For example, the food safety regulations of many countries and regions clearly stipulate the sanitary operation specifications and cleaning facility requirements for employees of meat processing enterprises. Having a complete personnel sanitation and cleaning station will help enterprises pass the inspection of regulatory authorities smoothly and avoid being punished for violations.
V. Layout and design points of personnel hygiene sanitation and cleaning stations
(I) Location selection
The personnel sanitation and cleaning station should be set up on the way that employees must pass to enter the processing workshop and close to the workshop entrance so that employees can perform sanitation and cleaning in time before entering the workshop. At the same time, it should maintain a reasonable distance from the raw material storage area, finished product packaging area, etc. to avoid cross-contamination caused by the flow of people.
(II) Spatial layout
The changing room cleaning station should be reasonably divided into different functional areas, such as hand washing area, disinfection area, dressing area, etc., and the areas should be properly spaced to avoid mutual interference. For example, the hand washing area should be equipped with a sufficient number of hand washing facilities to ensure that employees can wash their hands at the same time without crowding; the dressing area should be equipped with enough wardrobes to meet the needs of employees to store clothes and ensure good ventilation.
(III) Equipment selection and installation
Select appropriate models and specifications of sanitary cleaning equipment according to the scale and actual needs of the meat processing plant. The installation of the equipment should be ergonomic and convenient for employees to operate. For example, the height of the hand washing facilities should be moderate, the nozzle of the disinfection equipment should be easy for employees to use, and the equipment should be easy to clean and maintain to ensure its long-term stable operation.
VI. Future development trend of personnel sanitary cleaning hygiene stations
(I) Intelligent upgrade
With the continuous advancement of science and technology, personnel hygiene cleaning stations will develop in the direction of intelligence. For example, the use of intelligent sensing systems can automatically identify whether employees have completed all sanitary cleaning steps, and can issue reminder alarms if they have not completed them; using big data technology, analyze employees’ sanitary cleaning data, such as hand washing time, disinfection frequency, etc., so that enterprises can better manage and optimize sanitary cleaning processes. At present, our hygiene station equipment has met these requirements.
(II) Environmental protection and sustainability
Future personnel hygiene cleaning stations will pay more attention to environmental protection and sustainability. In the selection of disinfectants, more environmentally friendly and degradable disinfectants will be used to reduce pollution to the environment.
