✹ About Thursday 26 June 1662 Louise Hudson on 27 Jun 2015 • Link Worms in fish won't kill you. There are worms in fish even today and we've all probably feasted on them. Preservation methods being so primitive in Pepys' time would have meant most fish were infested. Rather than pickling, per se, fish were probably brined with salt--though not long enough on the day sturgeon was placed before Pepys. The refrigerator was, no doubt, a matter of simultaneous invention, like the typewriter. Everyone on earth needed to preserve food and everyone needed a reliable way to do it. Someone, somewhere was bound to come up with mechanical refrigeration sooner or later. The person(s) who got it going would have been the one(s) who got the credit, which has happened with most inventions (of which necessity is always the mother).
