Animal Mortalities

The purpose of mortality disposal is to prevent the spread of infectious diseases to humans and animals.

This applies to both wild and domesticated animals, birds and aquatic species. Interesting to note is that the deadly Ebola outbreaks in Central Africa resulted from handling infected carcasses. Aquatic species can be carriers of human pathogens like Edwardsiella tarda and atypical Mycobacterium. Similarly can Swine Flu and Avian Flu that infect humans, be traced back to infected birds and animals.

The effect of infectious diseases spreading among animals and birds can result in catastrophic mortalities and economic losses. Sometimes preventative culling is required to contain outbreaks. Nobody will ever forget the pictures of culled animals in order to contain Mad Cow Disease in Great Britain. Unfortunately, similar incidents gets reported every couple of months.

Prior to the development of MAAHP by Convertech, historical disposal options included incinerating, landfills, burial, rendering, composting and re-feeding to aquatic animals etc.

Mortality disposal can contaminate soil and water and lead to health risks for animals and humans. Secondary problems like rodents, insects, human and animal scavenging etc. need urgent solutions. Historical disposal methods are not very effective, or too expensive and sometimes not very eco-friendly. We sincerely believe in destroying pathogens at the source and provide cost-effective solutions to mortality disposal problems.

I need to get rid of dead fish from our hatchery. Which ecological process would be environmentally friendly and effective to use? Could I dump the remains in a pit covered with lime?
Please help.

Hi Philip,

Thank you for contacting us.
It is relatively easy to treat and recycle of any type of animal tissue waste, including fish, using a variety of methods. To give you any kind of sound advice I would need to know a bit more about the quantity of fish that you need to dispose of as well as the time interval (i.e. 200kg every second day etc.). Also of importance is if you need to control pathogens that could potentially spread disease back to your hatchery.

I presume that smell suppression is at the hart of your problem at the moment hence your question about lime. The quick answer to your question about burial with lime is it would certainly contain the smell by virtue of being covered by soil, but would not be the optimum method of getting rid of your problem on an ongoing basis. The lime, at least in theory, is supposed to assist soil dwelling bacteria in breaking down (hydrolyzing) the protein bonds more rapidly due to an increase in pH, but in practice this is not very effective method unless substantial volume of lime is used.

Please feel free to contact me on my cell 082 8414 996 if you feel that a quick discussion could help you solve this. I will be happy to assist you in any way I can.

Kind regards
Piet Kruger
