HIV has not been spread through food. The virus does not live long outside the body. You cannot get it from consuming food handled by an HIV-infected person; even if the food contained small amounts of HIV-infected blood or semen, exposure to the air, heat from cooking, and stomach acid would destroy the virus.

HIV is not spread through saliva
There is no evidence that people get infected with HIV by having their food prepared by HIV positive people. There are two main reasons for this:
1) HIV is only known to be transmitted in three ways: sexual transmission, blood-to-blood contact (injection needles and health care settings), and from mother to infant. Other routes of transmission are theoretical only. See "Can I get HIV from casual contact?" (http://www.cdc.gov/hiv/pubs/faq/faq31.htm).
2) HIV does not survive long enough in the environment to pose a real risk through contact of this sort. Scientists found that drying fluids containing very high concentrations of HIV(concentrations that are not normally encountered in day-to-day life) reduced the number of infectious virus by 90% to 99%. It is safe to say, based on these laboratory studies, that HIV would become uninfectious realitively quickly when exposed to the environment, making transmission through indirect contact with another person's fluids remote. See "Survival of HIV in the Environment" for more information (http://thebody.com/cdc/survival.html).
