Cebiche dinner considered harmful
In the South Pacific it's breakfast, lunch, and dinner. I could have Fijian Kokoda for every meal for a week, yuuuum!

Pacific style is with lime and coconut, it is still very acidic and fatty so not to everyone's taste

Could be specific fish types? But I have never had a problem

Once you add the lime juice to the fish it will keep longer without refrigeration

In Peru I suspect education is still lacking in food hygiene etc, so it may be a good move! (based on commentary from friends and relatives in Peru). Peru also has very traditions based cultures
