1. In these rules the Act means the Madras Prevention of Adulteration Act, 1918.
Cow'
s milk.
2. Where a sample of cow's milk (not being sold as skimmed or separated
milk)
contains less than 3 per cent of milk-fat, it shall be presumed for the purposes of the Act
,
until the contrary is proved, that the milk is not genuine, by reason of the abstraction there
-
from of milk-fat, or the addition thereto of water.
3. Where a sample of cow's milk, whether sold as cow's milk or as skimmed or
separated cow's milk, contains less than 8.5 per cent of milk-solids other than milk-fat, it
shall be presumed for the purposes of the Act, until the contrary is proved, that the milk is
not genuine by reason of the addition thereto of water.
4. Where a sample of cow's milk, whether sold as cow's milk or as skimmed or separated
cow's milk, contains less than 0.5 per cent of nitrogen, it shall be presumed for the purposes
of the Act, until the contrary is proved, that the milk is not genuine by reason of the
addition thereto of water
Buffalo's milk.
5. Where a sample of buffalo 's milk (not being sold as skimmed or separated milk)
contains less than 4.5 per cent of milk-fat, it shall be presumed for the purposes of the Act,
until the contrary is proved, that the milk is not genuine by reason of the abstraction
therefrom of milk-fat or the addition thereto of water.
6. Where a sample of buffalo's milk, whether sold as buffalo's milk or as skimmed or
separated buffalo's milk, contains less than 9 per cent of milk-solids other than milk-fat, i

shall be presumed for the purposes of the Act, until the contrary is proved, that the milk is
not genuine by reason of the addition thereto of water.
7. Where a sample of buffalo's milk, whether sold as buffalo's milk or as skimmed or
separated buffalo's milk, contains less than 0.53 per cent of nitrogen, it shall be presumed
for the purposes of the Act, until the contrary is proved, that the milk is not genuine by
reason of the addition thereto of water.
N.B. —The minimum limits for nitrogen in rules 4 and 7 above are intended to be used in those cases in which
the sample of milk when it is analysed is so far decomposed that an estimation of the proportion of milk-solids
other than milk-fat in the sample before decomposition will be unreliable, the proportion of nitrogen not being
appreciably affected by decomposition.
Cow's or buffalo's milk.
8. Where a sample of milk, separated milk or skimmed milk sold or exposed for sale
without any indication as to whether it is derived from the cow or the buffalo by a
comparison with the minimum limits given for cow's milk rules 2, 3 and 4 appears to be
adulterated, it shall be presumed for the purposes of the Act, until the contrary is proved,
that the milk is not genuine for the reason given in the rule or rules which are applicable.
Maximum limit for dirt in cow's or buffalo's milk.
9. Where a sample of milk, separated or skimmed milk, deposits, on standing for a
period of 24 hours, or less, an amount of visible sediment exceeding 5 parts per 100,000
(both milk and sediment being measured by volume), it shall be presumed for the purposes
of the Act, until the contrary is proved, that the milk is not genuine by reason of its contain
-
ing an excessive amount of dirt.
Butter from cow's or buffalo's milk.
10. Where the proportion of water in a sample of butter made from cow's or buffalo's
milk exceeds 20 per cent, it shall be presumed for the purposes of the Act, until the
contrary is proved, that the butter is not genuine by reason of the excessive amount of water
therein.
Ghee.
11. Where the proportion of water in a sample of ghee exceeds 1 per cent, it shall be
presumed for the purposes of the Act, until the contrary is proved, that the ghee is not
genuine by reason of the excessive amount of water therein.
