Instead of inspectors being on site all the time, they will only check once per shift.
The union representing inspectors and some industry watchdogs are critical of the change which the Trump administration said is the first in 50 years.
There have been some huge outbreaks of food poisoning traced to eggs in the United States, including a scandal in Iowa in 2010 that ended in prison terms for Jack DeCoster, father and son, and fines of $100,000 each.
In that case, about 1,900 people were sickened with salmonella and the company recalled 500 million eggs and lost $65 million.
The Centres for Disease Control said last May that eggs and poultry products remain the highest risk for food poisoning.
There are an average of 79,000 cases and 30 deaths from food-poisoning eggs in the United States.
