SAO PAULO, April 17 (Reuters) -

A JBS SA beef plant in the center western state of Goias was ordered shut for two days by labor auditors over irregular work conditions, one of them who inspected the facility last week said on Wednesday.

JBS immediately presented "an adaptation plan" which has been accepted by the Ministry of Labor and Employment and is being executed, the meat company said.

Notice of the closure was posted on the national labor auditors' union (Sinait) website earlier this week.

The auditors closed the plant on Friday after finding employees were routinely subjected to "exhausting" work shifts of 10 to 16 hours a day, auditor Roberto Mendes said, confirming details in Sinait's post.

The plant, with about 970 employees, was allowed to reopen on Monday after the company presented the plan to adjust work conditions, Mendes told Reuters. Auditors will verify those conditions on weekly basis, he said.

JBS said "activities in the unit were not interrupted and continue normally."

According to the Brazilian agriculture ministry, JBS' Senador Canedo plant is authorized to export beef to Egypt, Mexico, Singapore, China and other countries. The facility can process more than 80 cows per hour and has over 20 tons of storage capacity.
