Farmers generally store some common veterinary drugs. However, if the veterinary drugs are improperly stored, such as prolonged discharge, high temperature, mixed, damp, etc., the veterinary drug may be reduced in efficacy, invalidated, and even cause fatal damage to livestock and poultry. In order to avoid the harm caused by the farmers to the livestock and poultry due to improper storage of veterinary drugs, the following work should be done to store veterinary drugs.
Moisture proof
After being tidal, all kinds of veterinary drugs will be moldy, sticky, discolored, loose, deformed, smelly and even worms, completely losing their use value. Some veterinary drugs are very easy to absorb the moisture in the air, and after slowly absorbing water, they begin to slowly decompose into salicylic acid and acetic acid, which produces a strong sour taste and greatly increases the irritation to the stomach of livestock and poultry. In addition, oxygen in the air can oxidize the drug. Therefore, farmers should store veterinary drugs, whether they are taking internal medicine or external medicine, they must pay attention to moisture. The container for the charge should be sealed. If the bottle is to be tightly closed, seal it with wax if necessary.
Anti-light
Most veterinary drugs are chemical preparations. The ultraviolet rays contained in sunlight often catalyze the change of veterinary drugs, which can accelerate the oxidation and decomposition of veterinary drugs, and deteriorate the veterinary drugs. For example, vitamins and antibiotics can deepen the color, reduce the efficacy, and even become harmful toxic substances when exposed to light; adrenaline and nitric acid are also afraid of the sun. In the veterinary pharmacy, we saw a lot of dark and opaque grindstone bottles, that is, to protect the veterinary drugs from light. For veterinary drugs that are affected by light, farmers can take the following methods: veterinary drugs that are easily changed by light, wrapped in brown bottles or glass wrapped in black paper to prevent UV penetration; need to be protected from light. Veterinary drugs should be placed in a cool, dry place where light is not easily directed; veterinary drugs that are easily oxidized and decomposed, such as adrenaline, must be stored in a sealed, dark container. Special attention should be paid to the fact that the drug bottles supplied with veterinary drugs are tan and blue and should not be replaced. They should be stored in original bottles.
Choose the right temperature
Too high or too low temperatures can degrade certain veterinary drugs. Therefore, when storing drugs, the appropriate temperature should be selected according to their different properties. For example, penicillin is dissolved in water and left at 25 ° C for 24 hours, that is, most of the failure; various biological veterinary drugs such as vaccines for prevention, such as too high or too low storage temperature, will irreversibly reduce their effectiveness. The veterinary drugs which are susceptible to deterioration by temperature are stored as follows: "room temperature" means 1 ° C ~ 30 ° C; "cool place" or "cool dark place" means no more than 20 ° C; cold place means 2 ° C ~ 10 ° C. Generally, veterinary drugs can be stored at room temperature. Veterinary drugs that are usually volatile, decomposed, and susceptible to deterioration by heat must be stored at a temperature of 3 ° C to 10 ° C.
Avoid exceeding the shelf life
Most veterinary drugs are unstable due to their nature or potency, and they may deteriorate and fail if they are stored for a long time. Therefore, drugs that exceed the expiration date not only fail, but many drugs also produce or increase toxicity and side effects. To this end, farmers should store veterinary drugs in stages, in batches, and set up special cards, paying attention to the use in the near future to prevent expiration. If the stored veterinary drug is found to exceed the shelf life, it should be treated and replaced in time to avoid using veterinary drugs that exceed the shelf life.
Avoid mixing
Farmers mix and release veterinary drugs, which may lead to the use of wrong drugs, phytotoxicity or even death of livestock and poultry. Storage of veterinary drugs should be done: internal medicine and external medicine should be stored separately; especially disinfection, insecticide, deworming drugs, pesticides, rodent drugs and other dangerous drugs should not be mixed with ordinary veterinary drugs, so as not to misuse poisoning; no veterinary drugs empty bottles of pesticides Rat poisons; veterinary drugs must be placed in places that children cannot reach, to avoid accidental consumption of children and patients with abnormal mental status. In addition, the original veterinary drugs such as bottles, bags, boxes, etc. purchased, it is best to keep the original label, and try to use the original packaging. If there is no original packaging, it should be packed in a brown bottle, and the outer sticker should indicate the name, usage, dosage, role of the drug and caution, contraindications. In addition, the date of loading, the date of manufacture, and the validity period of the veterinary drug should also be indicated. For external use, it is best to use a red label or a red pen to distinguish and avoid internal use. Drugs whose names are easily confused should be stored separately to avoid errors.
Should be cleaned regularly
If the stored veterinary drugs are not cleaned for a long time, when the livestock and poultry have a sudden illness, it is easy for the pig farmers to use some deteriorating veterinary drugs, and the harm is not repeated. Therefore, farmers should always clean up the veterinary drugs stored in their homes, and clean them once every 2 months to 3 months. In time, clean up the eliminated, expired, mildew, inferior counterfeit, damaged packaging, and veterinary drugs with incomplete labeling. New drugs that are often used.
Do not litter expired remaining veterinary drugs
Many farmers have thrown away the remaining veterinary drugs, which is actually very harmful. In the event that the farmed poultry is eaten, it will produce phytotoxicity and drug resistance, increase the cost of breeding; if it is misunderstood by children who are not sensible and abnormally ill, it will seriously affect their health; eliminate expired veterinary drugs and chaos Throwing, not only pollutes the environment, but more serious is that some special-purpose drugs, such as penicillin, if handled by themselves, improperly protected or emitted into the air, may cause allergies or even death; some powder injection drugs can cause skin ulceration. Therefore, veterinary drugs that have no use value should be completely destroyed, and it is best to return them to the veterinary pharmacy for centralized treatment.
Do not mess with the cork
For different types of medicines, different stoppers should be used. Otherwise, the stoppers may be melted. For example, the stopper of chloroform, turpentine and other medicines should be ground glass stopper; the rubber stopper should be used for the sodium hydroxide.
Prevent rat bites and insects
For veterinary drugs packed in cartons, paper bags, plastic bags, etc., they should be placed in other closed containers during storage to prevent rat bites and insects.
