I did not purchase these smoked Sprats from Amazon. However, some years back, when I was less health conscious and less educated as a consumer, I used to buy them occasionally at a local international store (for much less). Having some experience with canned Sprats from Latvia I would like to share some of the experience and give my take on this product for those who are contemplating to purchase and consume it.1) They do not specify what oil they are using. From my experience the oil is not high quality. In fact I would say it is pretty bad.2) BALTIC WATERS ARE EXTREMELY POLLUTED (Google this "Baltic waters pollution") so I would be very careful eating anything coming from there.3) They do not provide any nutritional information (calories, sodium, fat etc.).4) The can is not made from a material of acceptable quality. Actually I am not sure if the tin is food grade.5) The sprats are smoked which is not particularly good for anyone consuming them on a regular basis. They are extremely soft and mushy so that there is no need to chew them; the fish are all soaked in some thick yellow oil and smell and taste smoky almost like low quality cat food (I would never feed them to my cat, however).6) I never saw an expiration date on the tin cans.7) From my past experience many cans were damaged (perhaps in transit) which could be potentially hazardous.
