Foodborne disease is a significant public health burden in Georgia, driven by traditional food practices (unpasteurised dairy, home-preserved foods, communal feasting), seasonal agricultural exposures and ongoing challenges in the cold chain and food safety inspection system. Georgia’s foodborne disease surveillance system operates through NCDC with mandatory laboratory reporting and a multi-agency outbreak investigation framework.
Major foodborne pathogens in Georgia
| Pathogen | Common vehicle | Seasonality | Incubation | Notifiable? |
|---|---|---|---|---|
| Salmonella spp. | Eggs, poultry, unpasteurised milk, raw meat; cross-contamination in food preparation | Peak summer (June–September) | 6–72 hours | Yes — weekly; clusters (≥2 linked cases) = 24 hours |
| Campylobacter spp. | Undercooked poultry, unpasteurised milk, contaminated water | Spring–summer peak | 2–5 days | Weekly reporting |
| E. coli O157:H7 / STEC | Undercooked beef, raw dairy products, contaminated water, fresh produce | Summer peak | 3–4 days | 24 hours (STEC/HUS); outbreak = immediate |
| Shigella (bacterial dysentery) | Contaminated water, unwashed produce, person-to-person | Summer; outbreak risk in institutions | 1–4 days | Weekly; outbreak = 24 hours |
| Staphylococcus aureus toxin | Cream-filled pastries, salads, sandwiches; temperature-abuse during food service | Summer peak | 1–6 hours | Cluster (≥2 cases with epidemiological link) = 24 hours |
| Clostridium botulinum | Home-preserved vegetables, fish, meat; low-acid canned foods | Year-round; autumn after harvest season | 12–36 hours | Immediate notification; antitoxin activation |
| Listeria monocytogenes | Soft cheeses (especially fresh Georgian cheeses: sulguni, imeruli), ready-to-eat deli meats, smoked fish | Year-round; higher risk in refrigerated RTE foods | 3–70 days | 24 hours; pregnancy/neonatal cases = immediate |
| Hepatitis A | Contaminated water, shellfish, fresh produce; person-to-person | Autumn–winter peak; associated with large gatherings (Georgian feasts/supras) | 15–50 days | 24 hours |
| Norovirus / viral gastroenteritis | Contaminated water, shellfish, person-to-person (highly contagious) | Winter peak; year-round outbreaks in institutions | 12–48 hours | Cluster reporting (≥2 linked cases) |
Outbreak investigation methodology
- Threshold for outbreak declaration — ≥2 cases with plausible epidemiological link (same food source, same event, same location, same time period)
- Notification — healthcare facility or laboratory notifies NCDC within 24 hours; NCDC deploys outbreak investigation team
- Epidemiological investigation — case definitions; line listing; attack rate calculation; food history questionnaire (meal-specific attack rates); hypothesis generation
- Laboratory sampling — stool specimens from ≥10 cases; food samples from implicated items; environmental swabs from food preparation areas; water samples if waterborne route suspected
- Food Safety Agency coordination — FSA inspectors deployed to implicated food premises; product recall if contaminated batch identified; international notification via WHO INFOSAN if cross-border food product involved
- Control measures — exclusion of food handlers from work while symptomatic; enhanced cleaning and disinfection; CCHF-specific measures if CCHF suspected; temporary closure of premises pending investigation
Georgian food safety regulatory framework
Food safety regulation in Georgia is led by the Food Safety Agency (FSA) — an agency of the Ministry of Environmental Protection and Agriculture (MEPA). The FSA is responsible for food safety standards, inspection, laboratory testing and product recall. Georgia has progressively harmonised its food safety legislation with European Union standards as part of the EU Association Agreement (DCFTA). The HACCP (Hazard Analysis and Critical Control Points) system is mandatory for food businesses from a specified threshold size. Import/export food safety certificates are issued by the FSA.

In plain language
Foodborne disease surveillance detects illnesses caused by contaminated food and water, investigates outbreaks to find their source and supports food safety controls along the food chain.
Key actions checklist
- Report clusters of gastrointestinal illness promptly
- Collect stool and food samples during outbreaks
- Interview cases with a standard questionnaire
- Coordinate with food safety authorities on recalls and controls
- Communicate prevention advice to the public

Questions and answers
How is an outbreak defined?
Two or more cases of similar illness linked to a common food or drink.
Who regulates food safety?
The national food safety authority, in coordination with public health services; see the regulatory framework section above.
