US health officials have confirmed that the full-fat dry milk used by 'By Heart' to manufacture infant formula could be the source of contamination that led to a food poisoning outbreak affecting dozens of children. Officials stated that tests conducted by the US Food and Drug Administration (FDA) found a type of bacteria that can cause illness in two samples linked to the infant formula. The agency found that the bacteria in an unopened can of milk matched a sample from a sick child and also matched the contamination discovered in samples of the full-fat organic dry milk used by 'By Heart', which were collected and tested by the company itself. Furthermore, FDA tests found contamination in a sample of full-fat dry milk supplied to 'By Heart', which matched the germ found in the company's final product. The agency stated in a press release that the results are not conclusive and that the investigation is ongoing 'to determine the source of the contamination'.
