Diagnosis of Nitrate and Nitrite Poisoning in Animals. As the concentration of methemoglobin increases, affected animals develops dyspnea, cyanotic mucous membranes, weakness, ataxia, muscular tremors; and, often, frequent urination. Severely affected animals may collapse and die quickly from anoxia.

Nitrates and nitrites are chemical compounds that consist of nitrogen and oxygen. A nitrate is made of a bond between a single nitrogen atom and three oxygen atoms. A nitrite is a bond between a single nitrogen atom and two oxygen atoms. Nitric oxide is a single nitrogen atom bonded to a single oxygen atom.
Nitrates are naturally high in certain vegetables such as leafy vegetables, beetroot juice and celery. Nitrogen is critical in both synthetic fertilizer and organic fertilizer like manure and vegetable compost. Through oxidization – or bonding with air – the nitrogen is transformed into nitrates. Nitrates are also found in fertilizers. When too muc...
The World Health Organization (WHO) and many researchers warn against eating too many processed meats because the nitrites and nitrates may increase one’s chances to develop cancer. When processed meats like bacon and hot dogs are heated, the nitrites interact with the amino acids and cause another chemical to be formed, nitrosamines. Nitrosamines ...
On one side of the argument, we have WHO and major scientists stating that excess intake of well water high in nitrates can lead to “blue baby syndrome” (methemoglobinemia or nitrate/nitrite poisoning). Others contend that methemoglobinemia was not caused by nitrate, but by fecal bacteria that infected the infants and produced nitric oxide in their...
Other adverse medical conditions have been associated with drinking contaminated water such as adverse reproductive outcomes, diabetes and thyroid diseases. Nitrates inhibit iodide uptake by the thyroid, potentially disrupting thyroid function.
Other researchers do not contend with all of that specific evidence However, they say that the human body can tolerate more nitrates and nitrites than the current advisory thresholds. Specifically, they point to natural vegetable sources and the importance of nitrates and nitrites. “Huh?” You ask. Yes. Bacteria in the mouth and gut convert nitrate ...
Keeping with the most widely adopted scientific theory that nitrates cause methemoglobinemia, the disease is caused by an excess intake of nitrates in many other animal species – particularly cows. This is commonly known as nitrate poisoning. Cattle and sheep are ruminant animals – they have a four-chambered stomach. This makes them more susceptibl...
We know that dogs can develop methemoglobinemia, but what about other diseases associated with an overabundance of nitrate intake? Unfortunately, most summaries published by the United States government agencies and WHO reference experiments conducted prior to 1990 that more than likely need to be updated. We attempted to find more recent published...
A research study published in 1973 by Kelley et al. stated that, “Continuous consumption of these sublethal levels of nitrate did notproduce a syndrome of chronic nitrate toxicosis characterized by thyroid dysfunction.” WHO appeared to think otherwise based on studies on Wistar rats. Due to the mounting evidence in human medicine that nitrates and ...
De Laforcade et al. conducted a limited study to find out if nitric oxide concentrations were higher in dogs with either chronic valvular disease (CVD) or dilated cardiomyopathy (DCM) compared to healthy controls, and to determine whether nitric oxide concentrations are correlated with type of cardiac disease, disease severity, medical therapy, or ...
Many species are susceptible to nitrate and nitrite poisoning, but cattle are affected most often. They are especially vulnerable because microorganisms living in the rumen convert nitrate into nitrite, which is 10 times more toxic than nitrate, before nitrite is finally converted into ammonia.

Nitrate itself is not toxic, only when it is converted to nitrite. Many species of animals are susceptible to nitrate poisoning, but ruminants are the most commonly affected. Ruminants are especially vulnerable to poisoning by nitrate because of the nitrate-reducing potential of rumen bacteria.
Jul 23, 2024 · Symptoms of sodium poisoning in dogs can include vomiting, diarrhea, excessive thirst, lethargy, and seizures. If you suspect your dog has ingested too much salt, seek immediate veterinary care. 3.
sodium content might be detrimental to canine health. This article reviews dogs’ sodium requirements and considers how the sodium content of pet foods compares with these dietary requirements and the diets of wild dogs. Relationships between sodium intake and the risk of disease are examined, along with the extent to which salt affects food
