Modern Day Industrial Shechitah

After the slaughter, the chicken is placed on a conveyor system and left to hang so that the blood drains from the body. The chicken is de-feathered, but the de-feathering must be done at a cold temperature. Non kosher chicken processors de-feather with a hot scald but this is explicitly prohibited by kosher law because the hot scald is deemed to cook the blood into the meat of the chicken. Not only is the hot scald prohibited, but any equipment used to perform a hot scald for non kosher cannot be used in connection with kosher at all. This is one of the many reasons that kosher poultry cannot be killed in a facility that also kills non kosher poultry.

After the chicken is de-feathered, a mashgiach (supervisor) will examine the chicken and remove any prohibited items and check for dislocated bones or torn tendons or holes in the chicken’s intestines that would render it non-kosher.

Afterwards, the chicken is soaked, salted and rinsed to take away any remaining visible blood.

At this point the chickens are packaged and sealed with a kosher symbol on the packaging so that kosher consumers can be assured of the animal’s kosher status. As kosher is regarded with the utmost reverence, great care is taken to guarantee the integrity of the kosher process.
