"She comes into the restaurant really mad, really screaming," recounted co-owner Cesar Izquierdo, according to city documents. He said she accused the restaurant of a handful of violations including cross-contamination for leaving an open can of beer, used for cooking, next to an uncut avocado.
"Right away she stopped screaming, she stopped everything, you know, she stopped the inspection," he told city officials. He said she assured him she could "fix you up."
The very next day Okoro was back. But this time as a vitamin saleswoman.
Izquierdo bought $391 worth of Nutrilite vitamins, according to records. "I was a little intimidated," Izquierdo recalled. "This was the inspector selling them."
Izquierdo and his wife, Julie, said that after the sale was complete the inspector told them the date of their upcoming reinspection and assured them that everything would be fine. When Okoro arrived on the promised date, she didn't come into the kitchen but issued them a passing grade nonetheless, said Julie Izquierdo.
The Tribune found three other Rogers Park restaurants where owners say Okoro peddled her vitamins. Yet neither the Izquierdos nor any of those owners complained to the city's Department of Public Health.
Finally, in November, after much deliberation and loss of sleep, Julie Izquierdo decided to report the incident — along with supporting documents — to an administrative law judge when she went to contest the fines. The administrative judge reversed the fines against Taste of Peru, and a city investigation then led to Okoro's resignation.
It's a sequence of events that lays plain the difficult relationship between the city's restaurants and its regulators. The city says it welcomes complaints from restaurant owners, whom a Health Department spokeswoman called "our eyes and ears."
But in the course of its investigation, the city did not reach out to any of the restaurants where Okoro tried to sell her vitamins. Meanwhile, some restaurant owners said they assume any concerns they express to the city are likely to fall on deaf ears or, worse, be used against them.
"There is (an assumption) in food business that they will suffer terrible consequences if they step forward," said Logan Square Kitchen owner Zina Murray, who launched a petition last summer to change Health Department policies but said few restaurants would sign it for fear of angering the city.
Inspectors, in particular, hold great power in the restaurant world because a bad report or temporary shutdown can cost owners thousands of dollars and jeopardize business.
The Izquierdos contacted the city only after being chastised by the administrative judge for not reporting the incident to the city inspector general. The judge also shared the couple's supporting documents with the Health Department.
Commissioner Bechara Choucair said that restaurants' fears of retribution are "absolutely not" justified and that he is working to improve the city's communication with business owners.
"My message has been extremely clear," Choucair said. "If you see something that's not right, call me, email me, text me, this (@chipublichealth) is my Twitter handle, call 311, even post something on Facebook."
Department of Public Health spokeswoman Efrat Stein characterized Okoro's situation as an isolated case of a "rogue inspector that was doing something she shouldn't have been doing," and pointed out that Okoro had failed even to report her second job to her supervisor, in violation of workplace rules.
Stein said the inspector was taken off the street immediately following the Izquierdos' testimony at the November administrative hearing and was presented in January with a recommendation of termination, to which she had five days to respond. At that point, Stein said, Okoro chose to resign.
In the past seven years, the time period for which data was available, Stein said, the department has never dismissed an inspector for unethical behavior.
