| Characteristics |
Mastitis
pathogens and bacteria from the teat surfaces will under good condition
make up about half of the TBC.Problems arise due to poor udder health
and inadequate teat hygiene.
|
Important
because they can survive hot cleaning.High counts may indicate problems
with plant cleaning.Heat resistance causes problems for milk processors.
|
Grow
at low tempratures and linked with poor bulk tank cleaning.Produce heat
resistant enzymes that cause problems for milk processors.
