According to fresh tuna suppliers, when fish or other types of seafood are delivered without being kept in the appropriate temperature range, bacteria will grow quickly and it may even lead to food poisoning. The risks associated with eating spoiled fish include nausea, vomiting, stomach pain and diarrhoea. In some cases, the bacteria from spoiled fish can cause serious illness and even death in certain extreme cases.
There are a few ways to ensure that seafood is kept in optimum conditions when it is being delivered. First of all, you should always be informed about which delivery methods your supplier uses. High quality seafood exporters in Sri Lanka use freezer trucks, however if they use an insulated vehicle with ice packs or dry ice then this will also keep the temperature low enough while it travels to its destination. You can also ask if they have a specific time frame for maintaining cold temperatures on their trucks during transportation times because some companies recommend a maximum timeframe after which spoiling could occur despite using cooling units. It is important to know what kind of equipment is being used and how it is being used. It really all depends on the type of seafood that you are receiving as well, and where they were harvested from, so if you are unsure about which methods your supplier uses then just ask them.
According to experienced fish processing companies, non-chilled deliveries of seafood can be very dangerous for consumers because they could cause foodborne illness. Seafood should always be kept at chilled temperatures to prevent these types of problems from occurring during transportation times. This means that generally speaking, non-chilled delivery methods pose a great risk when it comes to delivering fresh fish.
