Farm Hygiene Practice (FHP) is critical to the future of the animal industry. While there are cleaning and disinfectants to assist, it is necessary to prevent and eliminate disease causing agents. FHP is actually a plan to prevent the entry of a disease agent into a farm and spread among farms. Most parts of it just uses common sense, however a basic understanding of how diseases enter a farm, persist in farm and are disseminated, needs to be understood to be able to control it in a scientific approach.
Disinfectants are applied to disease causing agent in order to destroy bacteria, viruses, fungi and molds. Using the right types of disinfectants regularly is critical in helping prevent the spread of diseases. Since there are many types of disinfectants on the market, it’s important to understand how they work including their pros and cons in order to make an informed decision on how to best disinfect and protect your facility and farm.
A few important points about disinfection should be kept in mind before choosing the right disinfectant for routine farm use. First, it is important to select a disinfectant that is active across a wide spectrum of germs under the conditions in which it will usually be used. This includes hard water, contamination with organic material, and toxicity potential or its damage to environmental surfaces or skin and clothing.
Most disinfectants won’t work if the surface to be disinfected isn’t fairly clean before applying the disinfectant. Organic materials such as soil, plant debris (such as straw), milk, blood, pus, and manure often inactivate some disinfectants or protect germs from the disinfectant’s active ingredients.
Chlorine-based disinfectants are an example for this kind of problem. Chlorine, which is the active ingredient in bleach, is quickly inactivated by organic debris such as manure, and even milk, at the concentrations usually used on clean surfaces.
“Hard” water can reduce or destroy the activity of some disinfectants as well. Moreover, some disinfectant solutions are only active for a few days after mixing or preparing. It is advisable to prepare fresh solution of disinfectant. A solution prepared longer than a few days, or after it has become visibly contaminated by organic material like manure, may result in product inefficiency. It will also cause a false sense of security.
Disinfectants also vary considerably in their activity against the assorted germs (bacteria, viruses, fungi, and protozoa) that livestock producers are concerned about. For example, plain vinegar (4% acetic acid) will readily kill the foot-and-mouth disease virus, but it won’t do much to Mycobacterium sps.
Most commonly used disinfectants are not active against bacterial spores, the environmentally hardy life-form taken by the germs that cause tetanus, blackleg, botulism, and anthrax. Formaldehyde is effective against most spores, but it is not really a practical disinfectant especially as it is now considered a potential cancer-causing compound.
Lastly, disinfectants must have sufficient contact time with the surfaces to which they are applied in order to allow them to kill the germs. Contact time needed varies with the product and the germ. A quick splash in a foot bath with a dirty boot for example is not likely to accomplish anything except to give a false sense of FHP. With certain classes of disinfectants, sufficient concentration and contact time can overcome some of the above given problems; however, increasing the concentration or contact time is not practical and is not cost effective as well.
Zarcon, a farm hygiene product of Zagro is a powerful, fast acting, unique powder formulation of broad spectrum disinfectant against different strain of virus, bacteria and fungi. It has great efficacy on most of the pathogenic & economically impotent diseases affecting livestock industry such as Gumboro Disease, New Castle, IB, Avian Influenza, Foot & Mouth Disease (FMD), Salmonella, Hog Cholera, Swine Vesicular Disease, and PRRS.
Zarcon contains potassium peroximonosulphate with sodium chloride and organic acid as powerful oxidizer. This oxidizes glycoproteins, polypeptides, nucleic acid and carbohydrates. It reacts with sulphydryl groups in the nucleic protein. The organic acids in Zarcon combines with organic buffer to produce low pH without significant corrosive effect, control oxidizing activity and have selective virucidal activity.
Zarcon is ideal for use in farm operations such as hatchery, farm buildings and slaughter houses. It is fast acting yet has low toxicity profile thus, safe to man, animals and environment. It is effective in all disinfecting systems, including aerial spray. Administration is easy and is proven efficient on porous surfaces such as wood and against organic challenge in hard water and at low temperature. It is non-corrosive and non-tainting, leaving no unsightly residues in the applied surface. It is formulated in powder form so as to have ease in application yet guaranteed effectiveness for overall disinfection.
