Not everyone has modern, state-of-the-art designer hatcheries but with attention to detail the results can be as good. Starting with personnel, they should be provided with shower facilities and clean clothing daily and showering must include the head. The clean clothing should be placed beyond the shower and the whole ablution block should always be kept very clean. Staff must not leave the building until they stop work.<\/p><p>Visitors should be minimal and must also go through the same process. This must include persons brought in to mend and maintain equipment if it is beyond the experience of your own staff.<\/p><p>In the hatchery itself each section should be kept separate with mats soaked in disinfectant in each doorway and plastic doors will help to reduce problems and keep the airflow in different rooms separate. In many hatcheries now, rooms are separated by solid doors but unless controlled with sensors they are often left open which alters the pressure and compromises biosecurity. The more sophisticated the system and design the easier this is but on the other hand there is far more to go wrong and far more nooks and crannies to keep clean, air socks, conduits, pipes, tunnels etc.<br \/><br \/>The frequency of opening doors should be minimised to prevent air drawing from one room to the other. In critical areas of the hatchery, the air is maintained at a positive pressure, so contamination can not be drawn in through an open door. Doors, including one-way doors, help stop cross contamination between rooms.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-c7565b6 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"c7565b6\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Chick fluff can be a problem to human health and good airflow and a specially designed fluff tunnel will remove fluff which is also a carrier of any disease organisms present in the hatchers. Samples of fluff and also samples of meconium should be regularly monitored in your own or a veterinary laboratory.<\/p><p>The hatchery rooms must be kept clean and this includes all surfaces including the ceilings, ledges and tops of machines. Each room and each machine should be cleaned after use and contact plates should be examined regularly by yourselves or veterinary services to identify any problems. Many hatcheries do not have good enough facilities for filtering air so that bacteria and fungal spores can easily be drawn into the system. The latter can be a problem in some climates and vigilance is necessary. Good monitoring will tell you precisely where a problem might be developing and then you can take action.<\/p><p>It is as well to remember that staff can be carriers of many potential disease bacteria and viruses although it does not affect them in any way. Some hatcheries make a point of checking staff and if a problem is found that person can be kept out of the buildings until treatment has been effective.<\/p><p>As staff do not leave the building for meals it is usual to supply a canteen. In some hatcheries mixing of staff from one section to another is forbidden yet at mealtimes they all come together!<\/p><p>In a clean hatchery problems are unlikely but washing hands before and after using the canteen and strategically placed disinfectant mats in the doorways will minimise any disease problem. Large modern hatcheries are equipped with separate canteens for the staff working in the clean or the dirty area in order to avoid the crossing of people.<\/p><p>As with the ablution block, the canteen should be cleaned daily and waste etc. removed. The canteen should be after the shower block so that the staff can leave their food there before entering the main building.<br \/><br \/>Develop a good relationship with your veterinary services and be aware of regulations in your own country which might affect the hatchery.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-ce61891 e-flex e-con-boxed e-con e-parent\" data-id=\"ce61891\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-1f81d79 elementor-widget__width-initial elementor-widget elementor-widget-heading\" data-id=\"1f81d79\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Cleaning<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-a30170e elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"a30170e\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>For every hatchery room, instructions for cleaning and disinfection should be formulated and pinned up in the particular room.

Since organic material inhibits the chemical action of disinfectants, it is very important that all surfaces to be disinfected are free from debris before applying the disinfectant. Depending on the degree of soiling this is done by:<ul><li>First dry cleaning with a vacuum or sweeping.<\/li><li>Soaking of the surface with a foamcleaner.

It is crucial to conduct the monitoring programme regularly. Here, guidelines are given describing basic monitoring procedures to evaluate the success of hatchery cleaning. A more intense monitoring programme should be used to solve a specific problem and would include egg washes, chick sampling and bacterial identification.<\/p><p>To evaluate the effectiveness of a sanitation programme, the assessment of cleanliness and sanitation should be performed only after clean up has occurred. For microbial monitoring, use is often made of solidified agar in Petri dishes containing nutrients that match the metabolic needs of bacteria and fungi. Bacteria and fungi grow on this media when put in an incubation cabinet. They will multiply and become visible as colonies. The number of these colonies indicates the hygienic state of the surface or air sampled.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-298bd97 e-flex e-con-boxed e-con e-parent\" data-id=\"298bd97\" data-element_type=\"container\" data-e-type=\"container\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t<div class=\"e-con-inner\">\n\t\t\t\t<div class=\"elementor-element elementor-element-b0cd71f elementor-widget__width-initial elementor-widget elementor-widget-heading\" data-id=\"b0cd71f\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\">Flat surfaces<\/h2>\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-8d4ffc2 elementor-widget__width-initial elementor-widget elementor-widget-text-editor\" data-id=\"8d4ffc2\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t\t\t\t\t\t<p>Rodac plates are plastic plates of which the bottom side is filled with agar gel.
