Question about raw cow milk

[Guest guest]

Hi All, i run a food private home based food co-op and have 2 different farms we

herdshare with and get milk from. One farm in particular never has consistent

tasting milk.

I am wondering anyone on here might know what would cause milk to be barny

flavored and the cream to be really gelatinous on top.

I keep getting emails from people (i agree with them) about how one week this

specific farms milk will taste fine and the next it will taste really strong of

grass/hay/barn like. One lady said she was standing by her kitchen window when

hubby was outside mowing and when she opened and got a whiff of the milk she

figured it was him mowing. Then realized her window was still closed and it

was the milk.

The cream is not like other raw milk cream. We can shake this milk and cream

and it will not mix back in properly. Other milk breaks up easily and it might

have small lumps but this milk stay's in big clumps with this weird stringy

gelatin like texture to it. I have asked the farmer and she has no idea why it

is fluctuating.

They get hay and pasture minimal grains at milking. She replaced milk lines

with new ones and thought that was the problem said she was switching to old

ones it is still happening.

I am starting to get worried it might be a coliform/bacterial issue. Anyone

know what is going on?
