Data center cooling systems emit low frequency sounds that travel further than higher frequency sounds such as traffic and construction noise. Although people can't always hear low frequency sounds, these sounds can still impact human health. Exposure to prolonged or high levels of noise has been linked to higher blood pressure, heart disease, and decreased quality of life. This is caused by sleep disturbance and increased levels of annoyance. Lower frequency noises are generally ranked as more annoying in research studies than higher frequency noises of the same loudness.

Kellogg’s is removing all artificial food dyes from its cereals and replacing them with natural colorings from fruit and vegetable juices and plant-based ingredients. The company will begin producing new artificial dye-free cereals this fall. The change comes after pressure from consumers to remove the dyes, which have been linked to behavioral issues like hyperactivity and irritability in children. Younger children and children with ADHD, anxiety, or other conditions may be more impacted by artificial dyes.

Missouri has reported 1,095 cyclospora cases. St. Louis County health officials confirmed that many sickened county residents interviewed reported lettuce eating at Taco Bell. Missouri was one of six states recently added to the CDC's list of states included in the outbreak, bringing the total number to 15. There is a lag between when cases occur and when they are confirmed, and many people recover without seeking care, meaning case numbers are likely an undercount. As of August 5th, there have been two deaths, both people had underlying health conditions and lived in Michigan. For most people, cyclospora infections are not deadly.

As of August 10th, there have been 345 illnesses and 36 hospitalizations across 27 states caused by jalapeños contaminated with salmonella. Jalapeños sold by Coast Citrus Distributors have been recalled. The contaminated peppers were sold at Chipotle and Qdoba stores; both companies have since stopped serving the recalled jalapeños. Several Taylor Farms products including dips, salsa, diced jalapeños, and guacamole made using the jalapeños were also recalled. The products were sold at stores nationwide including Walmart, Target, Trader Joe’s, Kroger, and Whole Foods. Customers should return recalled products for a refund.

For only the second time in history the American Red Cross declared a national blood supply crisis. The U.S. blood supply has dropped to its lowest levels since January 2022, caused by declining blood donations and increased need for blood. The Red Cross is now limiting distribution of type O blood to hospitals, with some patients having to wait for blood that they need. People can help by setting up an appointment to donate blood. Information on who can donate blood and how to schedule an appointment can be found at Redcross.org.
