PERSONAL HYGIENE ; A KEY TO DISEASE PREVENTION IN FARMS.

Bio security is a set of protocols that are simple but specific that positively influence animal health,public health and ensure food safety. Personal hygiene is a key player in biosecurity.

 Personal hygiene plays a vital role in disease prevention. The use of protective clothing and shoes is a major way to stay safe and keep flock clean.

 The protective clothing could be disposable or reusable and the level protection required will depend on the case at hand. The normal protective clothing for every day farm use include, the overalls,gloves and boots.

The level of protection becomes more sophisticated in outbreak cases, where disposable protective clothing are worn.

There is also the use of nose guards/respirators, gloves and boots. The use of protective clothing and boots is coupled with hand washing and disinfection. The clothes and boots are to be washed and disinfected after every use.


 HAND WASHING: this can be done with soap hand sanitizers and disinfectants.The wash bowls should be placed at key points in the farm,and washing should be done before you enter farm and handle birds.

 Alcohol swipes also come in handy after washing, these can be used to ensure the hands are clean and germ free.

Foot dip.and vats filled with disinfectant are placed at entry of farms ,the disinfectants should be changed at regular intervals changed at regular intervals.

UNCONVENTIONAL ROUTES OF INFECTION WITH BIRD FLU VIRUS.

UNCONVENTIONAL ROUTES OF INFECTION WITH THE AVIAN INFLUENZA VIRUS. The H5N1 strain of the bird flu virus has been identified as the highly pathogenic strain that also affects man and if not properly managed can result in death. There are many routes of possible infection with the bird flu virus but some subtle unconventional routes are also a major cause of concern, these include the following; 1) Visitors on farm premises. 2) Exchange of farm tools and implements with neighborhood farmers. 3) Absence of foot dips, hand dips and washing points in farms, feed mills and drug stores. 4) Absence of proper litter management. 5) Contaminated feed stuff. 6) Water pollution. 7) Lack of proper waste disposal/manure. Non restriction of visitors to farm site is a major source of spread of diseases not only avian influenza but also other diseases. Visitors moving in and out of farm site act as fomites bringing in loads of pathogenic organisms setting up a foci of infection in the farm site. 

Most visitors come through other farms thus bringing in pathogenic organism from one point to another. Visitors must be barred from farm sites to forestall introduction of pathogens.

 2) Exchange of farm tools and implements with neighborhood farms, may appear inconsequential but it’s a grave risk as pathogens are exchanged freely between farms. A simple gesture of exchange of tools is a breech on bio security protocol that must be prevented. 

 3) Absence foot dips, tyre dips and hand dips, this is a major route of infection. Many farms don’t have tyre dips, neither do they spray tyres with disinfectants, before allowing such vehicles on farm premises. The hand dips are very important, a worker that has handled contaminated matter but have refused to wash and dip hands in disinfectant solution is a ready source for spread of infection. Farmers that have dips , don’t use proven disinfectants of high potency to prevent infection. The dips with disinfectants are not replenished at regular intervals, thus making a mockery of the whole process. 

 4) litter management is very important in poultry as a lot of pathogens arise from poor litter management. Farmers don’t usually take care of their litter especially in case of wetness. 

The most important aspect of litter management is litter treatment. The litter can be treated using potent disinfectant, this can be used in the powdery forms and sprayed on litter. When turned, this will kill any incubating pathogen without any detrimental effect on birds. 

 Waste disposal/manure; waste disposal management on the farm is another point of concern, as many farmers don’t dispose their waste properly, leaving them open on farm without any form of treatment on the farm, thus allowing flies and other pathogenic organisms breed in that area causing a nucleus of infection right on the farm. Some farmers bag their waste, but still don’t treat the areas where the bags are kept which is still a point of infection. 

The farmers that bag and prepare to sell make the mistake of allowing merchants to come in to the farm with their sacks to procure manure. This is also another route of infection, as the sacks brought in may harbor pathogens. Water pollution. 

 The water source is also another point of infection, and a major route of infection. If water source or point is not well covered, allowing birds to defecate in it thus contaminating the water source. The water source must also be disinfected to ensure safety , and prevent pathogenic organisms from infecting birds and contaminating floors and drinkers.

BIRD FLU.

Avian influenza is a deadly viral infection that have been ravaging poultry farms around the world.The rate of spread of the virus is very alarming, and although wild birds have been implicated in the spread of the virus,contamination and contact are routes for persistence of the virus in and around farms. The role of bio security in the prevention and curbing of spread of infection on farms cannot be over emphasized,the bio security protocol must be simple,easily adaptable and measurable.The simplicity of the protocol will ensure strict compliance, the bio security measures include the following; 1) Do not allow visitors to your farm. 2) vehicles coming into the farm area must pass through a vat filled with disinfectants or the vehicle is hosed down with disinfectants . 3) The farm area must be cordoned off and must have foot dips at entrance. 4)The farm hands must enter the farm site from an entrance then go to cloak room to change into clean disinfected farm wear. 5)The tools and personal wear must be washed daily and disinfected. 6) The drinkers must be cleaned and disinfected. 7) floors drains and working surfaces are to be cleaned and disinfected. 8)isolate new birds to farms ,in a separate section of farm. 9) The birds can also be sprayed in the cages using disinfectants. 10)The water source must be clean and cool, ensure the purity of water source by treating with chemicals. 11)Litter management is very important,scrap and pack litter and dispose properly. 12) Proper disposal of dead birds, and other waste matter from the farm. 13) The farm environs must be clean and devoid of grasses,or stagnant pools. 14)The disinfectants used in foot dips must be changed at regular intervals. Bird flu is indeed deadly and zoonotic depending on the strain of virus involved.The first major sign is high mortality of sudden onset,then bluish-purplish combs,shanks and crop region,swollen lids and diarrhea. When you observe any of such signs,do not start treating or vaccinating; just restrict access to your farm and notify your vet.
