As well as potentially leading to higher Bactoscans, this raises the potential for cross-infection with diseases such as mastitis from contaminated milking equipment,\u00a0<\/span>according to Ian Ohnstad, milking technology specialist with The Dairy Group consultancy.<\/span><\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.9.0″ _module_preset=”default”]<\/p>\n Thermoduric bacteria \u2013 heat-resistant, spore-forming bacteria that can survive pasteurisation and cause serious problems for milk processors \u2013 are also more likely to thrive.<\/p>\n Despite these risks, many cleaning routines on UK farms are both ineffective and inefficient and need closer attention.<\/p>\n It is critical that a regular, monitored routine is followed by all staff involved in the plant\u2010cleaning operation, Mr Ohnstad suggests.<\/p>\n [\/et_pb_text][dsm_dual_heading before_text=”Cleaning protocol” middle_text=” ” before_background_color=”RGBA(0,0,0,0)” _builder_version=”4.9.0″ _module_preset=”default” before_text_color=”#000000″ border_width_bottom_before=”5px” border_color_bottom_before=”#7CDA24″][\/dsm_dual_heading][dsm_dual_heading before_text=”Step one ” middle_text=” ” before_background_color=”#7CDA24″ before_padding=”4px|6px|4px|6px|true|true” _builder_version=”4.9.0″ _module_preset=”default” before_text_color=”#FFFFFF” before_font_size=”18px” border_color_all_before=”#000000″ border_width_bottom_before=”2px”][\/dsm_dual_heading][et_pb_text _builder_version=”4.9.0″ _module_preset=”default”]<\/p>\n Clean the parlour using low-pressure water to remove muck and debris from liners, clusters, long milk and pulse tubes.<\/p>\n A common mistake is to clean the external surfaces of milking equipment after the hot water cleaning cycle has begun.<\/p>\n This can bake faecal material to the surfaces, making it far more difficult to remove, says Mr Ohnstad.<\/p>\n \u201cAnother reason to avoid applying cold water to the outside of a metal pipe is that it will significantly reduce the temperature of the water being circulated inside,\u201d he says.<\/p>\n Maintaining a sufficiently high temperature to reduce bacteria and milk residues in the pipe is critical, so this attempt to save time is ineffective and wastes the energy used to heat the water.<\/p>\n [\/et_pb_text][et_pb_image src=”https:\/\/www.zirveyiz.biz\/wp-content\/uploads\/2021\/05\/sag\u0306imhane-bakimi-ve-hijyen-ic\u0327in-neler-yapmak-gerekir.jpg” alt=”sag\u0306\u0131mhane bak\u0131m\u0131 ve hijyen ic\u0327in neler yapmak gerekir” title_text=”sag\u0306\u0131mhane bak\u0131m\u0131 ve hijyen ic\u0327in neler yapmak gerekir” _builder_version=”4.9.0″ _module_preset=”default” border_color_bottom=”#000000″][\/et_pb_image][dsm_dual_heading before_text=”Step two ” middle_text=” ” before_background_color=”#7CDA24″ before_padding=”4px|6px|4px|6px|true|true” _builder_version=”4.9.0″ _module_preset=”default” before_text_color=”#FFFFFF” before_font_size=”18px” border_color_all_before=”#000000″ border_width_bottom_before=”2px”][\/dsm_dual_heading][et_pb_text _builder_version=”4.9.0″ _module_preset=”default”]<\/p>\n Once the clusters have been cleaned, they should be attached to the jetters.<\/p>\n This transfers vacuum to the wash manifold and leads to wash solution being drawn into the plant.<\/p>\n The jetters should also be cleaned as they may have become soiled during the previous milking and can introduce contamination into the circulating solution.<\/p>\n Any in\u2010line mastitis detectors should be checked and cleaned before circulation begins.<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.9.0″ _module_preset=”default”]<\/p>\n Then a three-phase cleaning cycle should begin.<\/p>\n 2.1.

This should be checked routinely, advises Mr Horton.<\/p>\n Checking the water temperature throughout the system is also critical. This can be achieved using temperature-sensitive stickers on piping and, at the exit pipe, by drawing water into a bucket and using a digital thermometer.<\/p>\n Where heat losses occur, it may be that the parlour is older or poorly maintained and cold air is being drawn in at joints and seals.<\/p>\n Insulation may also have broken down over time. A common failing is to leave wash troughs without a lid.<\/p>\n Often the hot water system could benefit from a redesign \u2013 water heaters are frequently sited in boiler rooms and pipes carry water long distances, even externally.<\/p>\n The outlet on a heater may be too small, drawing water out slowly and allowing it to cool quickly as it contacts the pipework.<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.9.0″ _module_preset=”default” hover_enabled=”0″ sticky_enabled=”0″]<\/p>\n [\/et_pb_text][et_pb_text _builder_version=”4.9.0″ _module_preset=”default” hover_enabled=”0″ sticky_enabled=”0″]<\/p>\n [\/et_pb_text][dsm_dual_heading before_text=” Time taken” middle_text=” ” before_background_color=”RGBA(0,0,0,0)” _builder_version=”4.9.0″ _module_preset=”default” before_font_size=”24px” hover_enabled=”0″ border_color_all_before=”#000000″ border_width_bottom_before=”2px” border_style_bottom_before=”dotted” border_width_left_before=”13px” border_color_left_before=”#EDF000″ locked=”off” sticky_enabled=”0″][\/dsm_dual_heading][et_pb_text _builder_version=”4.9.0″ _module_preset=”default”]<\/p>\n For effective cleaning and disinfection it is advisable to perform the full hot wash routine after every milking, and not just on a once-a-day basis.<\/p>\n Most milking parlour equipment manufacturers will advise a 10-minute wash.
