Health Minister Earl Howe repeated a statement on the Winterbourne View scandal on 10 December 2012.
The statement was made earlier in the Commons by Care Minister Norman Lamb and came on the day the government published a report on the scandal.
Mr Lamb told MPs the government was planning a "dramatic reduction" in the number of people with learning disabilities kept in hospitals in England.
Boards, directors and senior managers at private hospitals who allow abuse to take place will face tougher sanctions - including possibly criminal prosecutions, he said.
The move follows the abuse of patients by staff at the Winterbourne View private hospital, near Bristol, which was uncovered by BBC Panorama.
In the Lords, UK Independence Party peer Lord Pearson of Rannoch urged the government to examine the training offered to care workers.
He asked: "Are care workers proud of what they do or are they just in it for the money?"
Responding on behalf of the government, Health Minister Earl Howe said it was important healthcare workers were properly trained.
He told peers: "Contracts with learning disability and autism hospitals should be dependant on assurances that staff are signed up to the proposed code of conduct...and that there should be minimum induction and training standards for unregistered health and social care assistants."
