Must have been a really long time ago, or maybe just in a way different part of the country. I worked for Wonder Bread (Continental Baking) in the mid 80's and there was no formaldehyde anywhere around the plant.

Might be he smelled something else in the embalming compounds that smelled similar to what was used in baking?

I said I USED to know...like 30 or 40 years ago used to. There have been a lot of changes in the world since then.



Yep, there most certainly has been a few changes.

Have used a lot of it in the fish industry. Egg treatment, parasites. Nasty crap if you ask me.

One place I had to show the bosses I could get the same and better results with salt on our fry and cut back on using the stuff in the hatchery building. Resistant to change they were, at the expense of my health and anyone else around when I was treating. I like salt!


Saltwater is definitely a better option! Wish we could use it here but we are quite a ways up the creek from good saltwater. A few of the hatcheries I've worked at have pumps though and they utilize it. Hatch is so much easier with some saltwater in the mix.



I bet. I just used salt on the fry once hatched in the hatchery troughs. Turn down the water, put in the short standpipe, empty a 50lb bag of salt in with most of it at the head, wait for them to start losing balance, turn the water on, put in the tall standpipe again.

No dragging a jug of formalin from the 55 gal drum through the building, filling chicken waterers, breathing fumes etc. You probably know the routine.

Potassium Permanganate impregnated zeolite works for air. Not sure how it works in a contact situation.

We used to use chicken waterers on our heath tray stacks but we use a peristaltic pump on the head boxes that feed the nopads. Pretty slick deal but I don't miss the fumes. I had to treat the adults today but luckily that raceway is outside so its not too bad. I still wear a respirator though when I pump it out of the barrel. Some of the hatcheries in PWS still use hydrogen peroxide which is nasty crap too.

The issue with using saltwater straight out of the ocean is you have to run it through a UV system before it goes to any eggs or fish to kill anything in the water.

I'm very sensitive to form. and have found that lemon scented ammonia in a glass bowl left in a sealed area will help.
After that run an ionizer.

I've developed a sensitivity to Betadine too, along with Argentine and Ovadine.

You let your Doctors know, right.

Not good if you need to get operated on and some imaging requires an "iodine contrast" injection. Likely they have something else.

Amazed me I never developed the sensitivity to all those things. Tried my best to avoid it as much as possible. Bosses always seemed to want to use the strongest option first, I tended the other way.

I hear you on the raw water. That was our problem at the one place, our eggs were hatched in jars using raw river water, the jars sat in the indoor raceways they were going into when hatched, and the problem with using the formalin was that there were other things going on in the bldg and other people working there. No nasty fumes from salt, but bosses being bosses, things didn't always go my way. Never could figure out all the money they used for other crap, why not put some UV units on the hatching/rearing water inside?

If you saw how much we had to move our fish it would make your head explode.
