roducts is combined with the results of 190 evaluations of foreign objects
in food that were conducted by the FDA Health Hazard Evaluation Board over
a period of 25 years. Hard or sharp objects 7 mm or longer in size were fou
nd to be a potential health hazard from laceration, perforation wound, and
possible secondary infection. Objects less than 7 mm in size represent a po
ssible hazard, especially if a special-risk group (e.g., infants, elderly)
is among the intended consumers of the product. The results proved consiste
nt with U.S. Department of Agriculture guidance concerning foreign objects
in food. Hazard Analysis Critical Control Point applications for physical h
azards in food are discussed.
