Washington ( CNN ) -- The House Energy and Commerce Committee requested documents and information Monday from Wright County Egg and Hillandale Farms of Iowa related to the recent salmonella outbreak and egg recalls , according to a news release from the office of the committee 's chairman , Rep. Henry Waxman , D-California . Waxman and Oversight and Investigations Subcommittee Chairman Bart Stupak , D-Michigan , sent letters to the two Iowa-based egg producers asking for details on the contamination of their egg products , including when government officials and customers of the affected egg products were first notified of the contamination . The committee also asked for the inspection records for the companies ' facilities , the companies ' internal protocols and standards for monitoring and analyzing their products , and documents related to allegations of health , safety , environmental , or animal cruelty violations for the companies or any related companies , the news release said . Responses from each egg company are expected by Tuesday , September 7 , according to the letters . Hillandale Farms said it shared `` a number of common suppliers '' with Wright County Egg , including a company called Quality Egg , which provided feed and young birds . `` We are devastated that our eggs have been implicated in making people sick , '' Hillandale farms said in a statement Sunday . `` We have never had a product recall in our 45-year history , and it flies in the face of our mission to provide wholesome , nutritious food for the American public . We regret that anyone might have become ill , and the concern and disruption this has caused our customers . '' Both Wright County and Quality Egg are owned by the DeCoster family , which has a string of agribusiness interests in the Midwest and Northeast . Those companies ' records have come under new scrutiny since the recalls were announced earlier this month . In June , company owner Austin `` Jack '' DeCoster admitted to 10 civil counts of animal cruelty in Maine after a nonprofit animal welfare group conducted an undercover video investigation and forwarded its findings to Maine animal welfare officials . In a statement issued Monday morning , Wright County Egg said it was working with the Food and Drug Administration on the current recalls and defended its record . `` Wright County Egg strives to operate our farms in the most responsible manner , and our management team has worked closely with FDA through their review of our farms . We have reviewed [ FDA ] Commissioner [ Margaret ] Hamburg 's comments to the media , but because we have not received any written reports from FDA to date , it would be inappropriate to respond to her remarks . It is important to note that any concerns raised verbally during FDA 's on-farm visit were immediately addressed or are in the process of being addressed , '' the statement said . `` When issues have been raised about our farms , our management team has addressed them swiftly and effectively , working with recognized outside experts to identify and implement corrective measures for our operations , '' it said . `` We are approaching our work with FDA in the same forthright manner . '' The Energy and Commerce Committee is n't the only group on Capitol Hill looking for answers . The chairwoman of the House FDA and Agriculture Appropriations Subcommittee , Rep.Rosa DeLauro , D-Connecticut , sent a letter Monday to Agriculture Secretary Tom Vilsack and Hamburg , asking questions about the recent egg recall . In the letter , DeLauro asked the United States Department of Agriculture and the FDA , which share jurisdiction in this area , about the investigation into the DeCoster farm 's safety record and the oversight of its operations . She also inquired about the possibility of the tainted eggs being used by federal nutrition programs .
