Food safety training is widespread, but training coverage, certification, delivery methods, and measured knowledge vary substantially by role and business type. In a CDC study using 2012 data from six U.S. EHS-Net sites, 94.8% of kitchen managers and 90.4% of food workers reported ever receiving food safety training. The same study found a much larger gap in certification: 78.7% of managers versus 36.0% of food workers reported ever being certified. UK tracking data from 2023, meanwhile, found that 93% of surveyed small and micro food businesses provided at least some food-safety-guideline or regulation training.

Training coverage and certification
The CDC restaurant study separates three related measures: whether someone had ever received training, whether they had ever been certified, and whether a manager held a current certificate. Those measures should not be treated as interchangeable.
Among interviewed kitchen managers, 94.8% reported ever receiving food safety training. Among interviewed food workers, the corresponding figure was 90.4%. Certification was less common: 78.7% of kitchen managers and 36.0% of food workers reported ever being certified in food safety. For managers specifically, 70.6% reported holding a current food safety certificate. These are 2012 study data from six selected U.S. EHS-Net sites, not a national workforce estimate.

The restaurant requirement data also show that certification was not universal at the business level. In the sampled restaurants, 71% required kitchen-manager certification. Among certified managers, 78.1% said their certification came from an accredited organization. Among certified food workers, 76.3% reported an accredited organization as the source of certification.
Training immediately before an examination was common among people who reported certification. Among certified kitchen managers, 98.9% said they received food safety training immediately before the certification test. The comparable figure among certified food workers was 90.1%. These figures describe the reported pathway to certification; they do not establish that the training caused a passing result or that every certificate remained current.
| Measure from the six-site CDC restaurant study | Kitchen managers | Food workers |
|---|---|---|
| Ever received food safety training | 94.8% | 90.4% |
| Ever certified in food safety | 78.7% | 36.0% |
| Training immediately before certification test, among certified people | 98.9% | 90.1% |
| Certification from an accredited organization, among certified people | 78.1% | 76.3% |
Training formats and certification pathways
Certified and trained managers reported using several formats, so the percentages are not intended to add to 100%. Classroom training was reported by 90.0% of certified, trained kitchen managers. Manual or employee-handbook training was reported by 86.9%, while video or DVD training was reported by 76.5%. Other written materials were reported by 67.7%, on-the-job training by 51.9%, and online training by 32.0%.
Food workers reported a different mix among certified workers who had received training. On-the-job training was the most frequently reported listed format at 56.9%. Manuals or employee handbooks were reported by 42.6%, video or DVD training by 36.0%, and other written materials by 28.0%.
The role difference is useful when interpreting training statistics. Manager training in this study was frequently classroom-based and supported by formal materials. Food workers more often reported learning on the job. The results do not measure which format was most effective, and they do not compare online, classroom, written, or video training under a common experimental design.

Knowledge outcomes by role and topic
Training coverage did not mean that every participant passed the knowledge assessment. The CDC assessment was passed by 55.3% of kitchen managers and 52.3% of food workers. Mean total knowledge scores were 74.9% correct for kitchen managers and 68.6% correct for food workers.
Topic-level averages varied considerably. Kitchen managers averaged 91.5% correct on hand-hygiene questions, compared with 82.2% for food workers. On cooking-temperature questions, managers averaged 72.6% correct and food workers averaged 84.1%. On hot- and cold-holding temperature questions, the averages were 74.2% for managers and 75.2% for food workers.
The study also reported much lower results for selected subparts. Kitchen managers averaged 86.6% correct on cross-contamination questions, while food workers averaged 16.6% correct on the cross-contamination subpart. Kitchen managers averaged 15.0% correct on the foodborne-illness subpart. Because the study reports these as different assessment areas, the figures should be read as topic-specific results rather than as a single overall ranking of staff competence.
| CDC knowledge result | Kitchen managers | Food workers |
|---|---|---|
| Passed the food safety knowledge assessment | 55.3% | 52.3% |
| Mean total score | 74.9% correct | 68.6% correct |
| Hand hygiene | 91.5% correct | 82.2% correct |
| Cooking temperature | 72.6% correct | 84.1% correct |
| Hot- and cold-holding temperatures | 74.2% correct | 75.2% correct |
These knowledge figures come from the 2012 CDC study data and should not be presented as current national pass rates. They also do not show how scores changed after a specific course, because the supplied study results are observational rather than a before-and-after training trial.
How UK small businesses deliver training
The Food Standards Agency’s Small and Micro FBO Tracking Survey Wave 4 measured surveyed small and micro food businesses with fewer than 50 employees in England, Northern Ireland, and Wales. Fieldwork for the 2023 wave took place in October and November 2023. In that wave, 93% provided at least some food-safety-guideline or regulation training to staff. The corresponding figure in the 2021 wave was 98%.
The 2023 results describe a spread of delivery methods. Verbal food-safety updates were reported by 35% of businesses. Formal food-safety training for existing staff was reported by 25%, and online food-safety training by 24%. Formal food-safety training for all new staff was reported by 19%. A further 15% reported providing training without specifying a format.
Several named or physical resources were less common. The FSA Safer Food Better Business package was provided to staff by 9% of surveyed businesses. Booklets on allergy control were reported by 8%, food-safety posters on walls by 7%, and local-council food-safety information by 5%.
Because businesses could report more than one approach, these percentages describe overlapping practices. The 2023 and 2021 waves also measure different periods; the figures should not be interpreted as a precise change in the same businesses unless the survey design supports that comparison. FSA, Small and Micro FBO Tracking Survey Wave 4
Advice, refreshers, and business-size differences
In the 2023 FSA wave, 30% of surveyed UK small and micro food businesses received advice or training about meeting food-safety standards in the prior 12 months. The comparable 2021 figure was 25%. These measures concern advice or training received during the stated period, not the proportion of businesses that trained every employee.
The survey also examined recall or withdrawal training among businesses with written recall or withdrawal procedures. In 2023, 77% conducted that training at least every three years. Within the same group, 55% conducted it at least annually and 22% conducted it every one to three years. The latter categories describe reported frequencies within the procedure-owning group and are not a complete measure of all food safety training.
Business characteristics were associated with different reported rates. At least-three-year recall or withdrawal training was reported by 91% of businesses with 25–49 employees. The rate was 86% among businesses packaging food to sell to other businesses and 84% among businesses packaging food on their premises. These are subgroup results from the 2023 FSA wave, not universal requirements or forecasts.
The FSA scope is important: the results cover weighted small and micro food businesses with fewer than 50 employees in England, Northern Ireland, and Wales. They should not be generalized automatically to large manufacturers, every UK food business, or businesses outside those nations. FSA, Small and Micro FBO Tracking Survey Wave 4
Food allergy training coverage
Food allergy training was less common than general food safety training in the six-site U.S. restaurant results from 2014. At their current restaurant, 44.4% of restaurant managers reported food-allergy training. The corresponding figures were 40.8% for food workers and 33.3% for servers. The study covered six selected U.S. EHS-Net sites, so these are not national restaurant workforce estimates. CDC, Restaurant Food Allergy Practices — Six Selected Sites, United States, 2014
Among people who reported allergy training, the topics covered were more consistently reported. Preventing allergen cross-contact was included according to 96.7% of trained managers, 98.8% of trained food workers, and 84.6% of trained servers. Training on the major food allergens was reported by 92.7% of trained managers, 86.0% of trained food workers, and 86.5% of trained servers.
Training about the response to a customer reporting a food allergy was reported by 80.5% of trained managers, 90.7% of trained food workers, and 94.2% of trained servers. The denominator matters: these topic percentages apply to the trained subgroup, not to all managers, workers, or servers in the study.
Taken together, the 2014 allergy figures distinguish training availability from training content. Fewer than half of the surveyed role groups reported allergy training at their current restaurant, but among those who had received it, most reported coverage of cross-contact, major allergens, or customer-response procedures. The findings are historical and site-specific; they should not be described as independently verified current coverage rates.
