Six persons who consumed the HelloFresh meal kit bought between July 2 and July 21 ground beef, which comes in 10-ounce vacuum-sealed packages, wound up in the hospital.

According to a statement made Wednesday by the U.S. Centers for Disease Control and Prevention, experts are investigating whether any other ground beef may be contaminated.

In addition to "EST.46841" inside the USDA inspection mark and "EST#46841 L1 22 155" or "EST#46841 L5 22 155" on the side of the container, the infected packages are labeled "ground beef 85% lean/15% fat."

The CDC also recommended discarding any frozen ground beef and cleaning any surfaces and containers it came into contact with. E. coli poisoning can cause vomiting, diarrhea, and severe stomach cramps. Three to four days after ingesting the germs, they typically begin.

Although the CDC stated that "it usually takes 3 to 4 weeks to determine if a sick person is part of an outbreak." seven infections have so far been reported. It "affects a small portion of HelloFresh customers in the US who received ground beef from one specific supplier." HelloFresh stated in an email statement.
