This is a comprehensive article of studies on cat parasite outbreaks reported from 1967 onwards. The goal is to find out if there are any changes in the pathway for transmission of the disease, as well as the source of cat parasitic diseases and infections from dogs and cats worldwide.
A cat parasite is a zoonotic disease caused by Toxoplasma Gondii, a mandatory intracellular parasite, which exists worldwide, that can infect mammals and birds All warm-blooded animals can be intermediate hosts However, only the cat family is the only main host and also the only host capable of discharging follicles that pollute the environment. Infection with dogs and cats parasite.



.
Cysts and cysts are the two main forms of infection for cats parasites (Toxoplasma gondii), cats and dogs parasites to humans. Before 1990, the parasite that existed in meat was the main way of transmitting disease to humans. Beef could be the cause of 3 disease outbreaks, one in the US was 5 patients, two in Brazil were 6 and 99 patients, respectively. However, cattle are less likely to form cocoon parasites in meat, so cattle have little epidemiological value.
Why do humans infect cats and dogs parasites
Eating habits are the main route of infection for cats parasites, especially raw or undercooked meat Some ethnic groups have traditional dishes that are raw meat, such as the kibbe made from raw lamb in the Middle East This dish is the cause of 5 outbreaks from 1975 to 2006, 2 in Brazil, in the UK, USA, Australia each country has 1.
Cat parasite cysts are sensitive to temperature, so cooked meat is less likely to cause illness in humans. In 1990, the Brazilian government organized a campaign to prevent infection of dogs and cats, tapeworm larvae, and tapeworms. Eating raw meat and undercooked meat is condemned, thus reducing the rate of cat parasite infection by eating meat.



.
The livestock industry has improved significantly in recent years, helping to reduce the risk of zoonotic infections, making meat safer. In addition, food manufacturers and processors complete the frozen technology, usually the meat will be frozen at −10 ° C for 3 days or −20 ° C for 2 days, with this temperature will make Significantly inactivates cat parasite cysts in meat.
Foods that easily infect dogs and cats parasites
Eating wild meat increases the risk of transmitting parasites to dogs and cats and has been the cause of sporadic outbreaks around the world in recent times. Wild animals that live in the wild, meat that is not quarantined contains many health risks, not just a source of parasitic infection Cat parasites can infect all warm-blooded animals, so many types of bush meat are delicacies on the banquet table such as wild boar, deer, etc. Numerous studies have shown that atypical strains of Toxoplasma gondii can cause serious illness even in people with normal immunity, much worse than typical Toxoplasma disease (i.e., the parasitic Toxoplasma strain above). cattle and domestic animals). The reason is that people have little contact with Toxoplasma strains of wild animals so they do not have immunity.



. In 2009, Pino and colleagues reported a case of soldiers infected with heart parasites from drinking unboiled water when he was on duty in the forest.
In addition, Carma and colleagues reported 16 cases of severe Toxoplasma infection in Guiana All patients mentioned above have a completely normal immune system. 87.5% of cases have lung lesions. The infection of Toxoplasma gondii dog and cat parasite isolated from 3 people showed as atypical strain. 31.25% of cases using bushmeat.
Infection with milk parasites caused 3 outbreaks from 1975-1988, mainly from drinking fresh goat's milk. Goats can excrete the active parasite of cats in milk.



The active form of the cat parasite is not inactivated during the fermentation of milk to make cheese. Methods for pasteurizing milk can reduce cats' risk of infection with cats. Methods of pasteurizing milk such as Pasteur, Brucella and tuberculosis also prevent the infection of dogs and cats. From the 1900s onwards, there was no outbreak of milk from the above methods.
