Read the following description of dairy cow mastitis due to infection with Streptococcus agalactiae and answer the question below. Streptococcus agalactiae is a highly contagious cause of mastitis. The bacteria is adapted to the udder and is only found in the mammary tissue, milk or on the skin of recently milked teats. S. agalactiae infection causes both sub-clinical and clinical mastitis, with most cases occurring during lactation. Bacteria can only survive for short periods in the environment.S. agalactiae infection in dairy herds persists mainly through the presence of infected cows who act as a source of infectious agent. Infection is transmitted from cow to cow mainly in the milking shed through contamination of milking machines with bacteria and through poor milking hygiene (contamination of milkers’ hands, udder cloths and other equipment) and poor milking machine maintenance (incomplete milking, fluctuating or excessive vacuum pressures etc).Infection can be diagnosed through testing of milk from individual cows or from bulk milk samples. Intra-mammary antibiotic treatment is highly effective at eliminating infection in most cases with a small proportion (<10%) of infected cows remaining persistently infected after treatment.. QUESTION: Which of the following statements about control of Streptococcus agalactiae  is FALSE?Select one alternative:Control should be based on year-round detection of mastitis followed by treatment because it is not possible to eliminate the bacteria from the environment.Isolate and treat infected cows and test milk after treatment and only return cows to the milking herd if they are free of infectious agent.Best practice milking hygiene and milking machine maintenance are important to prevent spread from cow to cow in the milking shed.Quarantine and culture any introduced cows to prevent introducing an infected cow.
