What it means
Violation 10 appears on the Chicago Department of Public Health’s inspection checklist as “Adequate Handwashing Sinks Properly Supplied and Accessible.” Its position on that form places it in the priority band — the city does not publish a severity field, so this is inferred from the code number, which is how the form itself is ordered.
Priority violations address the most direct routes to foodborne illness — temperature control, contamination, sick employees, unsafe sourcing. A single one can fail an inspection on its own.
How much it actually matters
Ranked by how often it is written up, violation 10 is 5th of 50. Ranked by how strongly it predicts a failure, it is 26th. It is written up far more than its risk warrants — a common finding, and the reason a long violation list is not by itself alarming.

How these figures were calculated
The city publishes the records but not these rates. They were derived from 56,625 inspections since 2022 with a graded result of Pass, Pass w/ Conditions or Fail, with each violation string parsed for its leading code number. The rate above is the share of inspections citing violation 10 that ended in a failure. A single inspection commonly cites several violations, so codes are not mutually exclusive. Anyone can reproduce this from the dataset linked above.
