Aptamil is investigating a complaint that some of its baby milk is linked to 11-week-old Roman , pictured with his mother Laura Stevens , getting food poisoning . Aptamil is investigating a complaint that some of its baby milk might be linked to an 11-week-old boy getting food poisoning . Laura Stevens found 50p-sized blood spots in her son Roman 's nappy and took him to the doctors . He was sent to hospital where he remained for a week with constant diarrhoea and a temperature . Doctors said he had a campylobacter infection but could not give a source . Miss Stevens , a first-time mum , said the only food she had given her son was Aptamil milk powder - but the company 's initial quality checks have come back clear . The 30-year-old , from Swindon , Wiltshire , said : 'Roman 's tests came back and showed he had food poisoning . ' I was gobsmacked , his insides had swollen from the food poisoning and the blood was the bacteria trying to get out of his little body . ' The insurance worker said Roman was left lethargic and pale while he was in hospital . The strain of bacteria is commonly found in meat and poultry . While Aptamil is investigating she has stopped giving Roman the product and switched to a different milk product . Miss Stevens , who lives with Roman 's dad Luke Embling , also 30 , added : 'As a first-time mum , I started panicking when I saw the fresh blood , it did n't stop for nearly a week and the diarrhoea was constant . ' I was terrified he was bleeding internally or I 'd done something wrong in pregnancy . I did n't know what to do . ' Aptamil confirmed it is investigating and said it had not had any other complaints . A spokesman said : 'We are aware of this complaint and are concerned to hear that Roman had been unwell . Miss Stevens , who lives with Roman 's dad Luke Embling ( left ) , said the only food she had given her son was Aptamil milk powder - but the company 's initial quality checks have come back clear . 'We have been in contact with her and are pleased that he is recovering . 'All our milks are manufactured to stringent quality standards including high temperature processing and a number of quality tests before they are released for sale . 'We have checked our production records and know that all of the quality checks were carried out . We have not received any other similar complaints . 'We are happy to help with any independent investigation but have not yet been contacted . ' Public Health England said it had not been asked to investigate but were aware of a confirmed case of campylobacter in a young child in the Swindon area . A spokesman said : 'Most infections are sporadic and it is difficult to trace it back to the exact source . 'Microbiological testing would have to be carried out to confirm it was the same strain that linked the patient and the implicated food . 'Without this , there is no way of confirming an association to a particular product . '
