Foodborne Illnesses A foodborne illness is a disease transmitted to people through food. An illness is considered an outbreak when: Two or more people have the same symptoms after eating the same food An investigation is conducted by state and local regulatory authorities The outbreak is confirmed by laboratory analysis 1-2
Slide 3-

Challenges to Food Safety Challenges include: Time Language and culture Literacy and education Pathogens Unapproved suppliers High-risk customers Staff turnover 1-3
Slide 4-

The Costs of Foodborne Illnesses Costs of a foodborne illness to an operation: 1-4 Loss of customers and sales Loss of reputation Negative media exposure Lowered staff morale

How Food Becomes Unsafe Five risk factors for foodborne illness: Purchasing food from unsafe sources Failing to cook food correctly Holding food at incorrect temperatures Using contaminated equipment Practicing poor personal hygiene 1-10
Slide 11-

How Food Becomes Unsafe 1-11 Time-temperature abuse Cross-contamination Poor personal hygiene Poor cleaning and sanitizing
Slide 12-

How Food Becomes Unsafe Time-temperature abuse: When food has stayed too long at temperatures good for pathogen growth 1-12
Slide 13-

How Food Becomes Unsafe Food has been time-temperature abused when: It has not been held or stored at correct temperatures It is not cooked or reheated enough to kill pathogens It is not cooled correctly 1-13 Pg 1.5 SSF 6e Pg 1.5 SSF 6e Pg 1.5 SSF 6e
Slide 14-

How Food Becomes Unsafe Cross-contamination: When pathogens are transferred from one surface or food to another 1-14 Pg 1.5 SSF 6e
Slide 15-

How Food Becomes Unsafe Cross-contamination can cause a foodborne illness when: Contaminated ingredients are added to food that receives no further cooking Ready-to-eat food touches contaminated surfaces Contaminated food touches or drips fluids onto cooked or ready-to-eat food A food handler touches contaminated food and then touches ready-to-eat food Contaminated wiping cloths touch food-contact surfaces 1-15 Pg 1.5 SSF 6e
Slide 16-

How Food Becomes Unsafe Poor personal hygiene can cause a foodborne illness when food handlers: Fail to wash their hands correctly after using the restroom Cough or sneeze on food Touch or scratch wounds and then touch food Work while sick 1-16 Pg 1.5 SSF 6e
Slide 17-

How Food Becomes Unsafe Poor cleaning and sanitizing: Equipment and utensils are not washed, rinsed, and sanitized between uses Food-contact surfaces are wiped clean instead of being washed, rinsed, and sanitized Wiping cloths are not stored in a sanitizer solution between uses Sanitizer solutions are not at the required levels to sanitize objects 1-17 Pg 1.5 SSF 6e
