Sick

Chipotle: a cautionary tale about letting sick staff prepare food

In 2015, people started getting sick after eating at Chipotle – a chain of fast food Mexican restaurants across the US.

Five people were infected by E. coli in Seattle. At least 234 people in California’s Simi Valley were infected with norovirus. In Minnesota, 64 people were diagnosed with salmonella poisoning from tomatoes. In Boston, as many as 141 students and other locals who ate at their local Chipotle were struck down with norovirus. And it continued – with more than 350 victims across the country that year.

In previous times, the cases might have been seen as isolated incidents, but with the rise of social media, the outbreaks were quickly linked and a pattern established.

The story became national news and Chipotle’s share price was laid as low as its victims. A Federal enquiry into the restaurant chain’s food safety practices was ordered, prompting more bad press.

Chipotle’s response

The fast food chain was initially dismissive of the reports. Co-CEO Monty Moran blamed “sensational headlines” in the media for making the issue bigger than it was.

But when customers began staying away in droves and it became clear that the public’s perception of the chain was ruined, founder and CEO, Steve Ells, appeared on national television and issued an apology to victims along with a promise of sweeping reforms to food handling practices.

In February 2016, 2000 restaurants across the country closed temporarily for employee food safety training.

Ells announced that their new procedures would make Chipotle “the safest place to eat”.

Food poisoning perception vs reality

While there were definitely other problems in Chipotle’s food safety procedures, around 75% Chipotle’s 2015 victims were norovirus infections.

There are between 19 and 21 million norovirus cases in the US each year. It is an extremely contagious disease that can spread from person to person with a touch. Outbreaks can occur in schools, churches, offices, sporting events and concerts.

Norovirus causes food poisoning-like symptoms such as diarrhoea, nausea and vomiting, but it is not technically food poisoning in the same sense as serving spoiled meat or raw foods containing salmonella.

However, food preparation is a very efficient vector for the disease – a single sick worker disease can pass the disease, via the food they prepare, to hundreds of people in one night.

This highlights the importance of not allowing sick staff to come to work.

While we don’t know the specific factors involved in the Chipotle outbreaks, anyone who has ever worked in a fast food restaurant will not find it hard to imagine a scenario where an overzealous restaurant manager pressured a young worker to come in for their shift when they weren’t feeling great.

Did Chipotle’s new “industry-best” procedures work?

The trouble with a procedure is that it must be followed for it to work.

The restaurant chain spent millions of dollars on food safety training for their staff and millions more on advertising to try and lure customers back.

Sales were steadily rising until food poisoning watchdog site, iwaspoisoned.com, began noticing a pattern of reports coming from a single restaurant in Virginia. The restaurant confirmed yet another norovirus outbreak, presumably from a sick staff member who failed to follow procedures. Chipotle’s problems now being national news, it wasn’t long before the story was across every medium. Chipotle’s already devastated stock price took another hit. Across social media, many declared that this was the last straw and they they would not be risking eating at Chipotle ever again.

The lessons that all restaurants need to learn

1) Take illness seriously

Don’t put pressure on sick staff to come to work. When employees do return, ensure they are actually well – if not, send them home again.

2) Teach good hand-washing techniques

Even norovirus is easily combated by simple soap and water and good washing techniques. And this doesn’t just mean at the start of the shift. This means every time staff members cough, sneeze, touch raw food or return from the bathroom.

3) Provide nail brushes at all wash stations

We have done hundreds of demos and hand washing training sessions using Glow 2 Show and we can tell you that the most commonly missed place is the nails.

4) Provide gloves and detectable plasters for staff with cuts or abrasions

There is no excuse for allowing food to come into contact with an open wound.

Latency explained

What is latency?

Latency, when it comes to temperature logging, refers to the delay between a change in temperature and when that change is detected and recorded by the logger. This delay can be due to the sensor’s design, the materials it’s placed in, or the logging interval. While it might sound like a disadvantage, latency can actually serve a useful purpose in certain environments—particularly where short-term temperature spikes are common but not harmful.

For example, in a busy commercial fridge, the temperature may briefly rise every time the door is opened. A logger with high latency won’t immediately react to these short fluctuations, helping to avoid unnecessary alarms or false data indicating a problem when there isn’t one. In these cases, a slight delay in response acts like a filter, focusing attention on real issues—such as prolonged exposure to unsafe temperatures—while ignoring the everyday ups and downs that don’t affect product quality or safety.

Differrnt connections

Connecting your logger

Depending on the type of logger you have, connecting your logger to your PC means either:

  • inserting into the Reader,
  • plugging it into a USB port, or
  • connecting it via a USB cable.

What's so good about USB?

First Generation LogTags use a separate Reader (sometimes called a dock) for configuration and for downloading recorded data. 

The Second Generation loggers only require a USB port or cable. Apart from saving the cost of the Reader, this makes them much better suited for shipping, because the recipient doesn’t need a LogTag Reader to download a report about the shipment’s journey.
