ISOLATION OF LISTERIA-MONOCYTOGENES FROM GOAT CHEESE ASSOCIATED WITH A CASE OF LISTERIOSIS IN GOAT

Listeria monocytogenes was isolated from the brain of a goat, which wa s euthanized due to listeriosis. A few weeks later a similar subtype o f L. monocytogenes was isolated from an on-farm manufactured fresh che ese which did not contain any milk from the goat which had suffered fr om listeriosis. A similar subtype was also found on 1 of the shelves i n the refrigerator where cheeses were stored. Prior to the onset of li steriosis, 1 fresh cheese had been made of milk from the actual goat, which may have excreted L. monocytogenes in her milk. Thus, the cheese made of this milk may have contaminated the shelves in the refrigerat or which then has served as a Listeria reservoir for new cheeses durin g several weeks.
