418 ANNUAL REPORT OF THE Off. Doc. 



Milk and cheese (as also Ice cream) sometimes undergo a decom- 

 position which develops a deadly poison called tyrotoxicon. Such 

 products art- so poisonous as to be totally unfit for human food. All 

 decayed or tainted animal products are unlit for human food and 

 are sometimes dangerously poisonous. Pigs sometimes suffer from
