According to Australian health authorities, a 68-year-old New South Wales man died from listeriosis late last month linked to the cheese made from pasteurized milk that has caused the death of two others and a miscarriage.  A further 23 people have also been infected with listeriosis.

Yesterday, the U.S. Food and Drug Administration today announced a draft quantitative assessment of the risk of listeriosis from soft-ripened cheese consumption in the United States and Canada. The risk assessment is a joint effort between FDA and Health Canada. View the Federal Register Notice for the assessment.

The new FDA/Health Canada draft risk assessment found that the risk of listeriosis from soft-ripened cheeses made with raw milk is estimated to be 50 to 160 times higher than that from soft-ripened cheese made with pasteurized milk. This finding is consistent with the fact that consuming raw milk and raw milk products generally poses a higher risk from pathogens than do pasteurized milk and its products.

While raw milk and raw milk products put all consumers at risk, the bacteria they may contain can be especially dangerous to people with weakened immune systems, older adults, pregnant women and children. View guidelines for avoiding illness by choosing milk and milk products carefully.

FDA invites comments that can help FDA and Health Canada improve:

  • the approach used;
  • the assumptions made;
  • the modeling techniques;
  • the data used; and
  • the clarity and transparency of the draft quantitative risk assessment documentation.
