These were not toxic.
Most larger cities have a local brand of meat packer that makes sausage, bologna, etc.
If they make pickle loaf, they are probably buying the relish for the pickles in 55 gallon, plastic barrels. These barrels are non-toxic by FDA regulation. It was cheaper to sell them to me than to ship them back to get the ten bucks. The dill and vinegar smell lasted a long time, almost a year, but it never hurt the fish or plants. The better solution is to avoid softer or flexible plastics wherever possible.
