ATG-Related Brucellosis Associated With Raw Milk Intake – Medical News



Warning from CDC in the US | 12 FEB 19

Several cases have been confirmed in the United States

Disease Control and Prevention Centers and State Health Officers are exploring possible exposures of Brucellla RB51 (RB51) in 19 countries associated with consumption of raw milk (unpasteurized) from the Miller Biodiversity Farm in Quarryville, Pennsylvania.

In New York, a case of infection with RB51 (brucellosis) is confirmed, and an unknown number of people may have been exposed to RB51 to drink milk from this farm.

This type of Brucela is resistant drug It may be difficult to diagnose because of limited testing capabilities and the fact that the early symptoms of brucellosis are similar to those of the most common diseases, such as flu.

The case of New York is the third known case of RB51 infection associated with the consumption of raw milk or raw dairy products produced in the United States. The other two human cases occurred in October 2017 in New Jersey and in August 2017 in Texas.

These cases report drinking of raw milk from a retailer online and from a Texas farm, respectively. In addition to these three confirmed cases, hundreds of others were potentially exposed to RB51 during these three incidents.

Symptoms of Brucella infection (brucellosis)

  • The initial symptoms of brucellosis may include fever, sweating, loss of appetite, headache, fatigue, muscle and joint pain and potentially more serious complications.
  • In pregnant patients, Brucella infections can cause a miscarriage.
  • Symptoms can start from five days to six months after the exposure.
  • People who are infected but not treated can develop more serious complications such as arthritis; heart problems; enlargement of the spleen or liver; and in rare cases, problems with the nervous system, such as meningitis.

summary

New York State Department of Health and Pennsylvania Health Department are investigating Brucella RB51 exposures that may be related to the consumption of raw (non-pasteurized) milk from the Miller Biodiversity Farm in Quarryville, Pennsylvania.

Brucellosis symptoms may include fever, sweating, malaise, anorexia, headache, fatigue, muscle and joint pain, and potentially more serious complications (eg endocarditis, hepatomegaly, splenomegaly and neurological symptoms).

In pregnant patients, Brucella infections may be associated with miscarriage. The onset of symptoms may occur from five days to six months after exposure.

background

This study is related to the third known case of Brucella RB51 brucellosis due to raw milk obtained in the United States. UU., August 2017. A New Yorker who drank raw milk purchased from the Miller Biodiversity Farm in Quarryville, Pennsylvania, was diagnosed with brucellosis in November 2018.

Dairy samples of milk products are positive for Brucella strain RB51. People who have consumed raw milk or raw dairy products from this milk production since January 2016 may have been at risk.

Patients who are still within six months of the date of the last intake of raw milk have an increased risk of brucellosis and adequateAfter exposure to rofilaxis (PEP), together with six months of symptom control,

If the patients are outside a six-month window After your last consumption of raw milk and having or developing a disease compatible with brucellosis, you should blood culture before commencing treatment, preferably while the patient is symptomatic.

Brucella strain RB51 is an attenuated vaccine strain of live cattle that can be eliminated in milk and can cause infections in humans. RB51 is resistant to rifampicin and penicillinNo serological test to detect RB51 infection.

Blood culture is the recommended diagnostic test for exposed individuals that are symptomatic.

Consulting consumers

  • Raw milk and raw dairy products are those that have not gone through a process called pasteurisation that kills germs that cause disease.
  • RB51 is a live and attenuated strain used in a vaccine to protect cows against a more severe form of Brucella infection that can cause abortions in cows and serious human disease. Rarely, cows vaccinated with the RB51 vaccine can kill the bacteria in their milk. People who drink raw milk from cows spraying RB51 can develop brucellosis.
  • RB51 is resistant to rifampicin, one of the antibiotics commonly used to prevent or treat brucellosis. The CDC recommends that anyone who may have been exposed to RB51 should go to their doctor to check if they need antibiotics to prevent infection and develop symptoms.
  • People who have consumed raw milk or raw dairy products from this dairy farm since January 2016 may have been at risk and should talk to their doctor.
  • People who are still within six months of the date of the last intake of raw milk have an increased risk of brucellosis and should receive antibiotics to prevent infection and symptoms and to monitor their health to detect possible symptoms. for six months. If the symptoms develop, you should immediately consult your doctor for the test.
  • People who have taken the raw milk from this milk for the last time more than six months ago and have had symptoms of brucellosis but who have not received treatment should immediately visit their doctor to perform tests that can determine whether they are infected and need antibiotics to prevent long-term health problems. caused by brucellosis.
  • Discard the remaining raw or stored milk or raw dairy products from this dairy farm.
