In recent years, sheep milk has become a new consumption hotspot due to its rich nutrition and easy absorption. Little did they know that if consumed improperly, 'supplements' may also become' drugs'. Recently, it was reported that a 6-year-old girl developed symptoms similar to a cold after drinking freshly squeezed sheep's milk, causing her legs to ache and unable to walk. She was diagnosed with brucellosis. What is brucellosis? How should we prevent, control, and treat it? Brucellosis, also known as brucellosis, is an infectious disease caused by infection with Brucella. Brucellosis exists in humans and animals in more than 170 countries and regions around the world. It is a Class B infectious disease specified in the Infectious Disease Prevention and Control Law of China, which can cause zoonosis and cause serious health and socio-economic losses. In China, the pastoral areas in the north have higher incidence rate of brucellosis. In recent years, brucellosis has also occurred in southern non pastoral areas such as Guangdong and Guangxi, so it should not be taken lightly. Spring and summer are the peak periods of brucellosis. Brucella is a Gram negative polymorphous globular bacterium that grows intracellular and has no spore formation. Brucella can cause human diseases in sheep, cattle, pigs, and dogs, with the most virulent being Brucella ovis. After contact or infection with Brucella, the population can enter the human body through the skin or mucous membranes. However, the incidence and severity of symptoms are related to human immunity, bacterial count, and virulence. If the human body's immune system is strong after being infected with Brucella, and the disease will not occur after defeating Brucella; If the number of Brucella entering the human body is large and highly toxic, exceeding the combat power of the human immune system, it can cause brucellosis. The clinical symptoms of brucellosis include fever, excessive sweating, joint pain, and swelling of the liver, spleen, and lymph nodes. The harm of brucellosis is significant, therefore prevention and control measures must be taken. Avoid direct contact with infectious sources. In addition to infecting humans, Brucella can also infect animals such as cows, sheep, pigs, and dogs, causing animal disease. Animals such as sheep, cattle, and pigs with diseases, especially sheep, are the main source of infection causing human brucellosis. The general population, especially tourists visiting pastoral areas, should try to avoid contact with livestock; Occupational groups such as breeders inevitably need to have direct contact with livestock in their work, such as raising, milking, shearing, slaughtering, processing fur and meat, etc. In addition, contact with feces or secretions of diseased livestock, such as milk, amniotic fluid, urine, etc., may also cause infections and diseases. Therefore, occupational groups should take good personal protection measures during work, such as wearing work clothes, rubber gloves, masks, hats, aprons, and rubber boots; In work, it is necessary to standardize operations, cultivate good work habits, and carry out harmless treatment of sick animals and related items to ensure that they are non infectious; After completing work, disinfect individuals, workplaces, and equipment. ■ Avoiding oral entry of Brucella can survive for 6 weeks in refrigerated cream, 30 days in frozen dairy products, 50-100 days in fresh cheese, weeks to months in dairy products, and 5 to 4 months in water. If one is not careful in their diet, they may be infected with Brucella and cause brucellosis. However, even the most tenacious vitality has fatal drawbacks, and the fatal point of Brucella is its fear of heat. Therefore, it is necessary to purchase quarantine qualified beef and mutton from legitimate channels and cook them before consumption. Cutting boards and knives should be made
