Safety Tips
What to Look For
-
Prawns cooked thoroughly until opaque and curled
Properly cooked prawns change from translucent to opaque white with pink/red edges and naturally curl into a 'C' shape. This indicates they've reached a safe temperature to kill potential bacteria.
-
Fresh seafood storage on ice or refrigeration
Before cooking, prawns should be stored cold to prevent bacterial growth. Good vendors keep their seafood chilled until the moment of preparation.
-
Made-to-order preparation
Quality Isso Devil is cooked fresh upon ordering. Watch for vendors who prepare each dish individually rather than serving from a pre-made batch.
-
Clean, hot cooking equipment
A very hot wok or pan is essential for properly caramelizing the sauce and quickly cooking the prawns without making them rubbery. Clean equipment prevents cross-contamination.
-
Separate utensils for raw and cooked seafood
Responsible vendors use different utensils for handling raw prawns and the finished dish to prevent cross-contamination.
What to avoid
-
Gray or slimy-looking prawns
Discoloration or sliminess indicates spoilage. Fresh prawns should look firm and glossy with a clean sea smell.
-
Strong ammonia or fishy odor
Fresh seafood has a mild ocean scent. A strong ammonia or overly fishy smell suggests the prawns are past their prime.
-
Pre-cooked dishes sitting at ambient temperature
Isso Devil should be prepared fresh or kept properly hot. Seafood dishes sitting out can develop harmful bacteria, especially in warm climates.
-
Vendors with poor hygiene practices
Avoid vendors who handle money and food without washing hands, or who have visibly unclean cooking areas.
-
Undercooked prawns (translucent or mushy center)
Prawns must be fully cooked to a firm, opaque consistency throughout. Undercooked seafood poses significant food safety risks.
