Drew Barrymore and Hugh Grant are among the latest batch of celebrities to be warned they may have contracted liver disease Hepatitis A.

The stars have been alerted of the threat in the form of a letter from the Los Angeles County Department of Public Health.

The warning comes after health officials were alerted to a sick member of celebrity chef WOLFGANG PUCK's catering staff, who may have inadvertently infected guests at a party following the launch of new movie MUSIC & LYRICS on 7 February (07).

The letter, obtained by website TMZ.com, asks party guests to contact health bosses or doctors if they ate uncooked food served at the event.

The health officials list "Mini Potato Skins Bar: Sour Cream, Chives and Vermont Cheddar, Taco/Fajita Bar: Shredded Lettuce, Chopped Tomatoes, Shredded Cheese, Guacamole, and Sour Cream and 80's Comfort Station: Peanut Butter Fluffer Nutters" among the potentially contaminated items.

SANDRA BULLOCK and ADAM BRODY, who were also among the guests at the party, have received the letter.

The latest health alert comes after BEYONCE KNOWLES and the supermodel stars of the Sports Illustrated Swimsuit Issue were urged to get health checks last month (FEB07) after attending another Puck party, which featured the unnamed Hepatitis A carrier among the catering staff.
