AT LEAST 80 cattle have died from botulism linked to the landspreading of poultry litter as a pure fertiliser on close by farms, data launched to Noteworthy reveal. 

As a part of our FACTORY FARM investigation in collaboration with The Element and The Guardian into the poultry business on the island of Eire, we analysed the potential illness impression from poultry litter because the business continues to broaden.

Poultry manure is wealthy in nitrogen, phosphorus, & potassium and may act as a strong fertiliser, used for compost within the mushroom business and landspreading on tillage and vegetable farms to encourage crop progress. 

Nonetheless, there’s a draw back to the manufacturing of such portions of litter that, if poorly managed, could cause environmental impacts and human well being dangers, corresponding to water, air and soil air pollution, unfold of antimicrobial residues and pathogens corresponding to botulism.

80 cows lifeless from botulism

In line with information launched to our crew by the Division of Agriculture (DAFM), 16 farms have been inspected between 2011 and 2021 on account of issues over potential breaches of the codes of excellent follow for poultry litter. 

Breaches have been recognized throughout seven of the inspections, together with one case as just lately as 2021. A complete of 80 cows died or have been euthanised within the circumstances, 61 of which have been dairy cows. 

Botulism linked to the landspreading of poultry litter on close by farms was recognized because the trigger in every case. In a single case, three cattle have been euthanised or died on a farm the place there have been additionally poultry current and the litter got here from the farm itself. 

In one other case from 2019 in Cork, litter was faraway from poultry homes and piled within the tillage discipline about 500 metres from the grazing floor. In essentially the most impactful case recognized within the DAFM data, 19 dairy cows died throughout two farms in Cork in 2010.

Origin of the litter

In a press release, the Division mentioned that it may be troublesome to determine the farm of origin as tillage farmers usually obtain litter from a number of sources, with deliveries typically on to fields.

That is seen in a botulism case from 2018 wherein seven dairy cows died in Kilkenny after poultry litter was unfold on a neighbouring farm. The inspection report said the farm the place the litter originated from needs to be inspected “to determine if correct procedures are being adhered to”. 

When requested if this inspection passed off, DAFM advised Noteworthy that, as there have been a lot of litter deliveries from a number of poultry farms, “the definitive farm of origin couldn’t be recognized”. 

In half considered one of this investigation, we revealed that there are critical issues over the regulation of the poultry litter commerce on the island of Eire.
