Did newspapers exaggerate or downplay Wiley's poison squad test results?

Research question: How do the published Bureau of Chemistry reports on the poison squad compare with newspaper summaries of the same experiments, and did the press overstate or understate the health effects Wiley reported?

The Bureau's 1904 boric acid report attributed many test-subject illnesses to colds, influenza and grippe rather than to the preservatives 1. Its 1908 benzoic acid report instead concluded that benzoates cause serious digestive disturbances, with nausea, vomiting and headache 2, and it said the symptoms appeared in healthy people, not only the weak 6. A December 1908 New-York Tribune item quoted Wiley claiming more babies were killed by impure food than by all childhood diseases combined 21, yet the same dispatch recorded him saying it was impossible to determine what share of infant deaths patent baby foods caused 23. The facts do not include a newspaper summary of the digestion series itself, so they cannot show whether the press overstated or understated those digestive findings. A January 1909 Washington Herald item reported the referee board's finding that small daily doses of sodium benzoate were not injurious 14, a conclusion that differs from Wiley's 1908 findings 2.

The Bureau's own report attributes many of the test subjects' illnesses to colds, influenza, and grippe rather than to the preservatives.
"Unfortunately, in several cases, the members of the training table suffered severely from colds, influenza, and grippe to such an extent that their services were often lost during a whole period."

Wiley's report concluded that benzoic acid and benzoate of soda cause serious disturbances of digestion, with nausea, vomiting and headache.
"It is evident, therefore, that the administration of both benzoic acid and benzoate of soda results in serious disturbances of the digestive functions, with positive indications of illness, which may easily be increased to nausea and vomiting, while headache is a very common symptom"

Wiley argued that objections to administering the preservatives in tablets and capsules were groundless, because the preservatives in the quantities used produced no direct irritant effects.
"In the case of the preservatives employed, however, which in the quantities used produced no such effects, the objections are entirely g-roundless."

During the fifth preservative subperiod, the subject's indigestion, heartburn and burning sensation in the throat and stomach returned with renewed vigor, lasting about two hours after meals.

The report says the symptoms appeared in healthy people eating good food and living in proper sanitary conditions, not only in weakened individuals.

Wiley concluded that, from Series II, the preservative tended only slightly to reduce body weight.
"Judged by this rule, therefore, it is concluded from the data of Series II that the administration of the preservative tends in a slight degree to diminish the body weight."

The report extrapolates that children and people with weaker systems would suffer much more serious and lasting injury, though the test subjects were not such people.
"It is only fair to conclude, therefore, that under similar conditions of administration of benzoic acid or benzoate of soda in the case of weaker systems, or less resistant conditions of health, much more serious and lasting injury would be produced."

In Series II, every subject lost weight while receiving the preservative compared with the preliminary period.

The subjects were young, healthy men, so the report itself notes that effects on less resistant people would likely be stronger than those observed.

Wiley himself described the Series II weight data as contradictory and said too much weight should not be placed on it.

Only three men could take the largest doses of benzoic acid (about 35 grams total), and most others had to have the preservative partly or fully withdrawn.
"The maximum quantities of benzoic acid, therefore, given during the entire preservative period are 35 and 34.9 grams, and only three men were able to take these amounts."

The article reported that the Bureau's baby-food results were not yet published, and that the 'poison squad' label was not needed to show a food was unfit, since analysis showing harmful ingredients was enough.
