Bloodworms

  • We are currently upgrading MFK. thanks! -neo
I had an allergic reaction to bloodworms. My hands started to peel wicked bad. I know just feed them with gloves and I'm fine
 
I always thaw mine first in a bowl of tank water. Is it really ok to throw them in still frozen?

Yes. The fish will do just fine pulling apart the frozen bloodworms.
 
i take a plastic cup of tankwater and let it dissolve in there before pouring in the tank. otherwise, ill have one or two fish grab the cube before anyone else can get any.
 
I've read that you shouldn let any frozen food thaw by itself in the air and then add water and feed, something about losing nutrients if you just add tank water. I don't know how true this is but just letting you know.
 
Scientists Describe Bloodworm Allergen


Medical scientists have described an allergen found in bloodworms that may affect fishkeepers.

The paper, which has just been published in the Journal of Investigational Allergology and Clinical Immunology, describes the case of a 23-year old Spanish patient who became ill after feeding bloodworms to his fish.

His symptoms, which included a rash, rhinoconjunctivitis (a combination of rhinitis and conjunctivitis), breathlessness and difficulty swallowing, led to doctors trying to determine the cause of the allergic reaction.

After investigating a number of other allergens, ranging from mussel, squid, house dust and dust mites to prawns and mosquitos, the study eventually revealed that the man was allergic to Chironomid midges, and their larvae - bloodworms.

The study says that Chironomid allergies are rare and are only seen in those who handle bloodworms used for fish foods.

Practical Fishkeeping has previously printed a letter in the Ask the Experts column from a reader who suffered from the condition.

For more details see the paper: Cabrerizo Ballesteros S, de Barrio M, Baeza ML, Rubio Sot鳠M (2006) - Allergy to chironomid larvae (red migde larvae) in non professional handlers of fish food. J Investig Allergol Clin Immunol. 2006; 16(1): 63-8.




The principle allergin hasn't been definitively identified, yet. It is most likely an amino acid sequence of the monomeric hemoglobin component from the bloodworm.

Which, if I remember my biochemistry correctly, would stem from a protein in the amino acid sequece that has a tertiary structure which inhibits neuroreceptors, causing the allergic reaction. This would take quite some time to narrow down the specific cause.
