Lesions of gizzard by formaldehyde

The use of salmonids based on formaldehyde in food is prohibited in many countries, but not in all of them and that is why increasingly more often produce pathologies such as shown in the photos. The fight against salmonellosis is a global priority, but the resistance of this microorganism to many biocides, causes the increase of doses of levels that produce local toxicity in the gizzard of the birds. It is due to an exothermic reaction between formaldehyde and gaseous hydrochloric acid with the formation of formic acid.
