In the
nineteenth century mastitis was thought to be caused by, among others, swelling of the udder. The
swelling itself needed an external cause for explanation, which was looked for in
inadequate animal husbandry. Sloppy milkmaids and fraudulent cattle traders are
frequently found in the literature throughout most of the century. Two examples of the latter are given here.

Jourdier [calls himself farmer at Vert-Galant, but is a veterinarian],

[Describes
the prices at the market of horses, sheep and cattle]
“Milk
cattle reached a price of 150-250 fr [per kilogram]. The sellers, mostly small
farmers, have the deplorable habit of not milking the cows long before, in
order to make the udder look much bigger. This is a serious mistake, because
this barbarous actions may cause severe diseases: a more or less intense
mastitis, an obstruction of milk [galactophores] canals, frequently resulting
in loss by the beast of one or two teats. Sometimes it makes them ill-natured
and difficult to milk, due to the suffering they have endured, and which has
been excited by the noise of the crowd or the blows.”

and lecturer at the Veterinary Highschool of Munich]

Euterentzünding.’ Deutsche Zeitschrift für Thiermedicin 12 (1885) 7-8
[Describes
the etiology of mastitis in relation to different pathological-anatomical changes]
“… Frequently there are, in high- or
moderate-producing milk cows, e.g. by a too late milking-out (which is often
deliberately put into practice by traders, to demonstrate a fraudulent milk
profit), conditions in which milk droplets adhere abundantly [to the teat] …”
It should
be noted that Kitt was discussing the route of entrance of infectious agents.
I found at
least four times in the literature remarks on the fraudulent behaviour of cattle
traders or sellers of cows as contributing to cases of mastitis.
