In other words, whereas 10 years ago, nearly half our
"genuine" samples were about or above the average percentage
of fat as laid down by the Dried Milk Regulations
and the experience of expert agriculturists, to-day this proportion
has fallen to one-sixth, the remaining five-sixths
being below standard. It is clear that either the cows
supplying Bethnal Green milk have undergone some physical
change affecting the milk during the past 10 years, or their
milk has been altered in its transit from cow to consumer.
Put in another way, milk fat that formerly reached Bethnal
Green residents as a normal constituent of their milk is now
either not produced by the cows at all, or is being intercepted
before it reaches the consumer.
