Food Safety Atlas

Personal hygiene and staff illness

Technical reference

Ill food workers are a leading contributing factor in foodborne outbreaks, and is the classic case. Controls depend on people reporting symptoms, so how a business treats someone who reports is itself a food safety control.

In a US CDC review of foodborne outbreaks from 2009 to 2012, a food worker was implicated as the source in 70% of the 520 outbreaks where contributing factors were reported. Bare-hand contact with food was identified in 54% of the outbreaks where a food worker was implicated (MMWR 2014;63(22)).

A later CDC review of outbreaks at US retail food establishments, from 2017 to 2019, found ill or infectious food workers were a factor in 41% of the 500 outbreaks with an identified contributing factor. was the most common (MMWR Surveill Summ 2023;72(SS-6)). These are US data, and reporting methods differ, so treat them as a pattern, not a local rate.

A handler may shed a without knowing, and very small numbers of some pathogens, such as , can cause illness (, cl. 15 guidance). So feeling well is not proof of safety, and hand washing and keeping bare hands off food matter even on good days.
