Large use of antibiotics in cattle farms causes super bacteria to erupt in humans

Large use of antibiotics in cattle farms causes super bacteria to erupt in humans:

survey report shows that in 2018 the United States broke a strong resistance to Salmonella (Salmonella) outbreak two years ago for cattle may be some use of antibiotic drugs The sudden increase in volume is caused.

Between June 2018 and March 2019, the Centers for Disease Control and Prevention (CDC) reported a Salmonella enteritis epidemic called Newport , in which 225 people were infected in 32 states and 2 died.

This strain is resistant to several antibiotics , especially against azithromycin, making it difficult to deal with. Azithromycin is the main antibiotic for the treatment of Salmonella enteritis. Prior to this, azithromycin was rare for Salmonella failure, and the first case was seen in the United States in 2016.

2018 is a full-scale outbreak of this antibiotic. According to incomplete statistics, of the more than 200 infected people, 60 need hospitalization and 2 deaths.

Investigators tracked beef from the United States and queso fresco. This cheese is made from unpasteurized milk. Genetic testing has shown that the bacteria are present in cattle farms in the United States and Mexico.

According to a survey released last week by the CDC, the US Food and Drug Administration (FDA) found that between 2016 and 2017, the dose of macrolides used in cattle farms suddenly increased by 41%.

Azithromycin is one of the macrolide antibacterial agents. The principle of sterilization of the same class of antibacterial drugs is similar, so that one of the same class of antibacterial drugs is resistant to bacteria, and is generally resistant to this whole class of drugs.

Investigators believe that the large use of macrolides in cattle farms is likely to be the cause of the Newport epidemic.

The report suggests that in order to avoid the emergence of more multi-drug resistant strains like Newport, it is important not to use antibiotics unnecessarily in the herd, especially those that are important for the treatment of human infections.

In recent years, nearly 70% of all important antibiotics in the United States have been sold to farms for livestock use. Public health officials have called for a significant reduction in the amount of antibiotics used in livestock.

To reduce the chance of infection, health officials recommend not eating cheese made from unpasteurized milk. In addition, you should follow the known temperature recommendations for safe eating (ie, use the temperature probe to puncture the temperature read in the food center): steak, barbecue 62.8 ° C, and then rest for 3 minutes after cooking; beef burger stuffing The cake should reach 71.1 °C.
