Hypoglycemia may be seen several days after ingestion. These signs and weight loss may be the only responses seen in animals that do not bloat or aspirate oil. Some animals do not reestablish normal rumen function after ingestion and can develop a chronic wasting condition. After ingestion of oil, the feces may not be affected until several days later, when they become dry and formed, in the case of kerosene or lighter hydrocarbon fractions; in contrast, heavier hydrocarbon mixtures eg, motor oil tend to be cathartic.
Oil may be found in feces and rumen contents as long as 2 wk after ingestion. Regurgitated or vomited oil may be seen on the muzzle and lips. CNS signs attributable to pulmonary, dermal, or GI absorption of hydrocarbons or cerebral anoxia include excitability associated with aromatic fractions—benzene, toluene, etc , depression aliphatic or saturated low-molecular-weight hydrocarbons , shivering, head tremors, visual dysfunction sometimes associated with lead contamination , and incoordination.
Acute pneumonia and possibly pleuritis coughing, tachypnea, shallow respiration, reluctance to move, head held low, weakness, oily nasal discharge, and dehydrated appearance are seen in some animals that aspirate highly volatile mixtures; deaths usually are seen within days. Respiratory signs may be limited to dyspnea shortly before death in animals that aspirate heavier hydrocarbons.
Neutropenia, lymphopenia, and eosinopenia occur initially and are followed by a relative increase in neutrophils. There are a few anecdotal reports of abortion after exposure. Laboratory data in rodents support the occurrence of increased fetal loss and decreased fetal growth.
However, the doses necessary to affect the fetus were also sufficient to profoundly affect maternal health and weight. Aspiration pneumonia is the most consistent postmortem finding in animals that do not die of bloat. This may be accompanied by tracheitis, pleuritis, and hydrothorax if highly volatile fractions such as gasoline or naphtha are involved. Lung lesions are usually bilateral and found in the caudoventral apical, cardiac, cranioventral diaphragmatic, and intermediate lobes.
Affected portions are dark red and consolidated and may contain multiple abscesses. Encapsulated pulmonary abscesses may be found in cattle surviving up to several months after aspiration.
Skin lesions may be obvious after repeated topical application or severe exposure and include drying, cracking, or blistering. A hydrocarbon odor may be detected in lungs, ruminal contents, and feces. Adding warm water to the GI contents may cause any oily contents to collect at the surface, but finding oil in the GI tract does not in itself justify a diagnosis of poisoning; most oils have low toxicity if not aspirated. Samples of GI contents, lung, liver, kidney, and the suspected source should be collected for chemical analysis to demonstrate presence of hydrocarbons in tissue particularly lung and GI contents and to match those found in tissues and ingesta with the suspected source.
Samples must be carefully protected from cross-contamination during necropsy and transportation to the laboratory. Instructions from the receiving diagnostic laboratory should be checked to ensure collection equipment and transport containers are appropriate to prevent evaporative loss of important components and contamination. Positive chemical findings together with appropriate clinical and pathologic findings are confirmatory.
Bloat pressure should be released by passing a stomach tube if absolutely necessary to save the life of the animal; using a trocar risks forcing oil into the peritoneal cavity, which results in peritonitis. Passing a stomach tube dramatically increases the risk of aspiration, and extreme caution is necessary.
In the absence of bloat, the prime objectives are to prevent aspiration and to mitigate GI dysfunction. Rumenotomy to remove ruminal contents and replace them with healthy ruminal material is safer.
More chronic cases involving primarily hypofunction of the rumen may also respond to this procedure. Cathartics, if used, should be of the saline or sorbitol type; however, there is no evidence that they improve prognosis.
Recent information no longer supports use of oil-based cathartics for petroleum ingestion. Activated charcoal has occasionally been suggested for use in small animals.
Interesting article- how about Grapeseed oil which is widely used by the cosmetic industry for skin and hair treatment- but depending on whether the oil is refined or not one can use it as salad dressing or cooking. The question is: if the oil which is intended for skin care because of its valuable nutrients can also be used in the kitchen?
If the skin care oil has also been refined is it not lacking those nutrients and is therefore a hoax. Here is my research so what is truly besy? Cold pressed grapeseed oil from the wine industry is a healthy, affordable in 5L sizes for all uses including high heat. Not sure why we dont hear more of it, when source is local, everywhere! It doesnt involve cutting down rainforest for coconuts, palm or avocados, soy GMO or harming birds in olive groves. The rice industry uses huge quantities of water so not eco friendly overall.
Unfortunately, grapeseed oil is high in omega-6 fatty acids. Plus, unless organic, grapes are notoriously high in pesticides. Grapeseed oil is a modern invention of the wine industry to make money on what is typically a waste product.
It is not a traditional oil. High-oleic sunflower oil is high in monosaturated fat like olive oil, and is eco-friendly if grown organically without pesticides.
If pesticides were present in finished products, they would be detected. Very good article. Unfortunately most people are unware of the harmful vegetable oils. The best oil is Olive oil. I come from a mediterranean country where we use olive oil a lot and the benefits of it have been proven through many generations. Apart from its antioxidants it contains anti-inflammatory ingredients and prevents from heart diseases, diabetes and other diseases.
We also use olive oil as a natural medicine in some cases. Refined vegetable oils as margarine, and the other oils are the worst because vegetable seeds are being processed in really high temperatures in order to become oils, which produce all the harmful ingredients.
On the other hand cow or sheep butter is much healthier and tastier cause it comes out of milk. The solution is simple though not easy always. Try to cook and eat foods with olive oil or real butter. You did not actually explain why refined oils are bad… Actually, refining of oils is done to remove certain properties of the oil and extend its shelf life.
Research is showing that butter consumption at the turn of the century was about 18 lbs per person per year and the use of vegetable oils was non existent. That is no proof at all. You are talking about how PUFAs do not mean rancid by definition. They can get rancid if you expose the bottle to light, or leave it open for some time in contact with oxygen. Also, you can definitely detect if oil has gotten rancid by the smell… Furthermore, refining does not create trans fats.
Hydrogenation does. That is a different chemical process. Thanks for refining we can use oil for frying. If you use non-refined oil for frying, it will get oxydized soon because of its low smoking point. Hi, Firstly thank you for your information. Me Sourav from India. I found your article when I am doing research on what kind of oil is good for health on Google I think you should add about Mustard Oil prepared from Mustard seeds.
It has many nutritional benefits. In our country it uses in large amount along with Coconut oil. Hope to hear from you soon. Hello Saurav, It is good to know that people are getting aware of and discussing what they should use in day-to-day life.
I agree that mustard oil has many health benefits but it is banned in many countries such as the USA as it contains a high amount of erucic acid which is not good for heart health. One can also use unrefined or cold pressed ground nut oil and sesame oil as they are healthy and budget-free options. Surely they lie. Methinks they lack discernment and a meticulous commitment to total honesty. Please clarify.
This oil has a little bit of natural smell. But during cooking it vanishes due to cooking. Ghee is called clarified butter. It is prepared by just heating butter at medium heat, until the ghee fat component of buter separates out, and, then the ghee is filtered using a strainer. Therefore, this can be termed physical refining. The residual solids left after straining can also be fed to animals.
It is the best among all. I just read this in the link above, it details the bleaching process, I think maybe this is what Jane Doe is talking about?
I cant really tell from the description what it means since im very ignorant in this subject. But i think that Jane is just trying to say that when you say bleaching it sounds like its being soaked in peroxide bleach and that makes it sound a lot worse. Bleaching: The major purpose of bleaching is the removal of off-colored materials in the oil. Many impurities, including chlorophyll and carotenoid pigments, are absorbed by this process and removed by filtration.
Bleaching promotes oxidation since these natural antioxidants and nutrients are removed along with the impurities. It would be helpful if you could show the date of this article so it is clear which studies came before others. Remove all oil. Olive oil is just costliest, not better or worse than other oils. The supposed benefits of antioxidants are marginal. One month of using olive oil gives as much antioxidants as one orange or strawberries in a sitting.
Did you know that the body needs healthy fatty acids in order to absorb vitamin A, D, K and E? Without fat, you can eat all you want, but not really get much.
You will be constantly hungry, even if your belly is full. Heating any kind of oil can be harmful because the molecular structure of the atoms will change and usually bind in a way that requires more energy to break apart when it is being burned in our bodies. Because our body needs fat to absorb vitamins and nutrients which are things that we need. The fat should be saturated with those things. Naturally they will cause imbalance in alkalinity and acidity as well as atomic imbalance inside us.
That is why the body will try to get rid of them. Lucky for us, Vitamin D3-sulfur that we get from the sun, is able to move through both water and fats and does a great job cleaning out this stuff. However it tends to drag with it a lot of alkaline parts like potassium, calcium, sodium, magnesium and so on.

While regular flour, water, egg, milk and sugar combinations go bad relatively quickly, mineral oil keeps them at their prime for weeks.
Some chocolates are made with petroleum by-products. Any product that contains Olestra is also a cause for concern. From frozen chicken nuggets and pizzas to rice crackers and cookies, supermarkets are brimming with TBHQ. Petroleum derived products are commonly used in a kaleidoscope of food colourings. These are added to everything from corn chips to fresh apples. They contain acetylsalicylic acid, the active ingredient in a multitude of over the counter painkillers such as aspirin.
Food additives can also be packed full of petroleum. Canned products are a particular concern as oil is used to extend their shelf lives. Fuel for Thought A new ASTM International standard will help in the design and monitoring of graphite components for molten salt design nuclear reactors. Fuel for Thought Petroleum is an incredibly complex material, with the average sample made up of more than 20, unique elements.
